1. The iteration speed of automated equipment has accelerated, and the braking components of electric motors are experiencing an upgrade wave.
With the continuous iterative upgrading of industrial automation and intelligent equipment industries, various drive devices such as servo motors, stepper motors, variable frequency motors, and reduction motors are widely used in intelligent manufacturing lines, precision machine tools, logistics transportation, light industry manufacturing, and robot equipment, among many other fields. As the core driving unit of industrial equipment, the stability of the motor's start and stop, the accuracy of positioning, and the safety during operation directly determine the operation accuracy and production efficiency of the entire automated equipment. The electromagnetic brake, as the core safety control component of the motor, is responsible for locking the motor during shutdown, precise positioning, emergency braking, and overload protection.
Currently, industrial equipment is showing a trend of miniaturization, integration, high-speed operation, and energy conservation. The overall structure of the equipment is continuously simplified and compact, leaving less installation space for the supporting braking components. At the same time, the load demand of automated equipment is steadily increasing, and scenarios of frequent start and stop, high-speed operation, and precise positioning are becoming more common. Traditional electromagnetic brakes gradually reveal many shortcomings in compatibility. Common braking products on the market generally have problems such as large size, high weight, and insufficient torque density. To achieve high braking torque, large-volume equipment is required, which cannot meet the installation needs of miniaturized motors and compact equipment; while traditional small and lightweight braking devices have problems such as insufficient torque output, performance fluctuations in high-temperature conditions, and poor durability during frequent start and stop, making it difficult to meet the dual requirements of lightweight assembly and high-load braking.
In addition, traditional electromagnetic brakes have a single adaptability and mostly can only match specific specifications and types of motors. Manufacturers need to purchase multiple braking products for different motors and different working conditions, which increases the cost and difficulty of component procurement, storage, and maintenance, and restricts the standardization and integration upgrade of the equipment whole. Under the development trend of industry lightweighting, generalization, and high performance, electromagnetic brakes with high torque output, ultra-lightweight structure, and multi-machine compatibility have become the core upgrade direction in the field of motor components. At the recent large-scale industry equipment exhibition, a new high-torque lightweight electromagnetic brake was officially released, specifically addressing the industry pain points such as the inability to balance torque and size of traditional braking products, narrow motor compatibility range, and poor installation adaptability, providing a new domestic solution for multi-category motor components.
II. Core Weaknesses of Traditional Electromagnetic Brakes, Restricting the Upgrade and Development of Motor Equipment
Based on the data from the automation equipment industry and the feedback from terminal operation, traditional electromagnetic brakes have obvious performance and structural shortcomings when adapting to the operation of modern industrial motors. They cannot meet the current requirements for equipment upgrade and have become an important factor restricting the efficient, stable, and lightweight operation of motor equipment.
Firstly, the torque density is low, and the volume and performance are out of balance. The structural design of traditional electromagnetic brakes is outdated, and the utilization rate of the magnetic field and the efficiency of friction work are limited. Under the same volume specification, the output torque value of the braking force is low. In the case of medium and high-load motor conditions, problems such as insufficient braking force, positioning deviation, and excessive sliding buffer occur easily. To meet the braking requirements of heavy-load motors, only larger-sized and heavier brake models can be selected, resulting in an increase in the overall equipment weight, an overly bulky structure, and non-compliance with the design standards for lightweight equipment. It also affects the flexibility of equipment operation and energy consumption control.
The structure is heavy, and the integration adaptability is poor. The design of the shell, magnetic circuit, and spring group of traditional products has a high redundancy. The overall axial and radial dimensions are large, and the self-weight is high. Currently, most precision automation equipment, small robots, and compact conveying equipment have limited internal space. The heavy brake is difficult to be installed and embedded, and the integrated design of the equipment is restricted, unable to meet the assembly layout requirements of new motor equipment.
The model is not adaptable to multiple types, and the generalization is weak. Most electromagnetic brakes on the market are designed and developed for a single type of motor. The interface specifications, torque parameters, and installation dimensions have a narrow adaptation range, and they can only match conventional ordinary motors. They cannot be compatible with servo motors, high-speed variable-frequency motors, and large-torque reduction motors, etc., which are differentiated models. Equipment manufacturers need to match different braking accessories for different motor models, which makes the supply chain management cumbersome and the spare parts storage cost high, which is not conducive to standardized batch production of equipment.
The stability in high-frequency conditions is insufficient, and the maintenance frequency is high. The magnetic circuit design of traditional brakes is unreasonable. Long-term high-frequency start-stop operations are prone to serious coil heating, magnetic field attenuation, and torque fluctuations. The friction plate wears out faster, and after long-term operation, it is prone to problems such as delayed braking response and unstable locking. Frequent shutdowns for maintenance and component replacement are required, increasing equipment downtime losses and maintenance costs, and it is not suitable for the continuous and uninterrupted production mode of automated production lines.
III. New Product Core Technology Breakthrough, Achieving Dual Consideration of Light Weight and High Torque
The newly released high-torque electromagnetic brake at this exhibition, developed by the research team, focuses on the core pain points of the motor equipment industry. Relying on years of electromagnetic braking technology accumulation, the research team completed technological innovation from four dimensions: magnetic circuit optimization, structural reconstruction, material upgrading, and process improvement. It broke through the performance constraints of traditional products and improved the output torque capacity and operational stability while reducing the equipment volume and self-weight. At the same time, it expanded the motor compatibility range and achieved universal matching for various types of industrial motors.
(1) Optimize the magnetic circuit structure design, increase torque density
The new product abandons the rough magnetic circuit layout of traditional brakes and adopts precise closed-loop magnetic circuit optimization design. It re-plans the arrangement of electromagnetic coils, magnetic path, and magnetic field distribution, effectively improving the magnetic field utilization rate and reducing magnetic energy loss. Through precise calculation of coil turns, wire diameter, and magnetic gap spacing, the electromagnetic attraction force concentrates on the friction braking area. Under the same volume condition, the output torque capacity of the braking force is significantly improved, effectively solving the shortcoming of insufficient torque in traditional lightweight brakes. Under standard specifications and dimensions, this product performs better than the same type of conventional products and can easily match the braking requirements of medium and high-load motors, achieving the operation effect of small volume carrying large torque.
At the same time, the electromagnetic response logic was optimized, shortening the excitation and demagnetization time of the magnetic circuit, making the braking response faster, and enabling smooth start-stop switching. It can adapt to the high-frequency and high-precision start-stop operation mode of the motor, effectively reducing the positioning error during the motor start-stop process and improving the operational accuracy of the equipment.
(2) Integrated lightweight structure, simplifying redundant design
The R&D team reconfigured the overall structure in a modular way, eliminating the redundant external fixation structure and redundant protective components of traditional products. The spring braking unit, electromagnetic drive unit, and friction transmission unit were highly integrated and designed as a whole. By optimizing the mechanical structure of the housing, the axial and radial dimensions were significantly reduced while ensuring the structural strength and impact resistance of the entire machine. Compared with traditional products of the same torque level, the overall weight of the machine was significantly lower, and the ultra-thin and compact structure met the embedded and external installation requirements of various compact motor equipment.
The lightweight structure design not only reduced the weight of the brake itself but also effectively reduced the overall load of the motor equipment, reduced equipment operating energy consumption, improved the flexibility of the machine's movement, and was particularly suitable for mobile automation equipment, lightweight robots, and high-speed conveying equipment that require weight reduction of the entire machine. At the same time, the simple modular structure design made equipment disassembly, maintenance, and repair more convenient. Without complex disassembly procedures, it was possible to replace easily damaged parts, reducing the difficulty of operation and maintenance.
(3) New type of wear-resistant friction material, suitable for high-frequency and long-term operation conditions
The product adopts a new self-developed composite wear-resistant friction material, replacing the traditional general friction materials. After multiple rounds of high-temperature wear resistance, high-frequency start-stop, and anti-decay tests, it has the characteristics of stable friction coefficient, low wear and consumption, and strong high-temperature resistance. In the high-frequency start-stop and continuous braking conditions that generate high temperatures in the motor, there will be no obvious thermal decay, and the braking torque remains stable, eliminating problems such as braking slip and positioning deviation.
The new friction material is suitable for long-term continuous operation scenarios, effectively extending the service life of the friction plate, reducing the frequency of component replacement, and reducing equipment downtime for maintenance. At the same time, the excellent noise reduction performance of the material ensures a smooth braking process and low noise, meeting the noise requirements of precision workshops and indoor intelligent equipment.

The universality and compatibility of the design have been significantly improved.
The electrical control parameters are compatible with the conventional industrial 24V and 220V universal voltage system. It can directly connect to various motor control systems and equipment PLC systems, with high signal matching degree, no need for additional circuit modification, and convenient debugging and installation. It can quickly adapt to the upgrading and transformation needs of various new and old motor equipment.

It comprehensively verified the torque performance, durability performance, compatibility performance, and environmental adaptability performance of the product. The R&D team built a professional testing platform and conducted millions of high-frequency start-stop durability tests, simulating the 24-hour continuous high-frequency operation conditions of industrial motors. They continuously monitored core parameters such as torque output, response speed, coil temperature, and friction loss of the products. In response to the subtle performance fluctuations during the tests, they continuously optimized the magnetic circuit and structural parameters to ensure the stable long-term operation performance of the products. At the same time, they completed high and low temperature environment tests, dust environment tests, and load shock tests to verify the adaptability of the products in complex conditions such as temperature fluctuations, slight dust, and load fluctuations, ensuring stable operation in multiple scenarios.
During the on-site adaptation tests, the product was equipped with different specifications of servo motors, reduction motors, and stepper motors for real machine trial operation, covering various real working conditions such as precision processing, material transportation, automated sorting, and light industrial packaging. It verified the matching degree, braking accuracy, and operation stability of the product with various motors. Based on the feedback from the real machine operation, the interface accuracy and torque output logic were optimized to further improve the overall adaptability.
In the mass production stage, a standardized quality inspection system was established. Each downline product must complete multiple detection processes such as torque calibration, insulation performance testing, sealingity testing, response speed testing, and appearance size verification to achieve full-process control of product quality and ensure uniform performance and stable quality of batch products.
