YB series electromagnetic brake motor
YB series electromagnetic brake motor Overview
HM Motor has always adhered to the philosophy of “convenience, innovation, and excellence,” delivering high-quality, reliable, and intelligent products to customers. The YB series motor, equipped with an electromagnetic brake, represents an innovative achievement by HM Motor. When handling vertical loads or requiring rapid stops, the electromagnetic brake quickly locks the motor, ensuring the absolute safety of the mechanical structure. Even during power outages or interruptions, the fail-safe electromagnetic brake guarantees the safe operation of the mechanical system.
For user convenience, the YB series motor can only be speed-adjusted via a frequency inverter. However, for those needing speed control through a governor, HM Motor also offers the YF series speed-adjustable electromagnetic brake motor as an alternative option.
Moreover, HM Motor maintains stringent quality control, utilizing premium raw materials and cutting-edge manufacturing techniques. Every product undergoes rigorous testing and inspection. Additionally, we provide comprehensive after-sales service, offering technical support and solutions to our customers.

Characteristics of YB series electromagnetic brake motor
Safe and Reliable: The electromagnetic brake is designed for stability and rapid response, with a braking response time of less than 200ms and a total braking work lifespan of up to 4.6×10⁸ joules, ensuring user safety during operation.
Simple and Ingenious Design: When the brake loses power, the armature is released, and the spring resets it to press against the friction disc, locking the motor shaft as the friction disc grips it, holding the load in place. This straightforward and comprehensible structure is easy to maintain and service.


The electromagnetic system of the motor is optimized through ANSYS finite element analysis and simulation, ensuring stability, reliability, higher efficiency, and lower temperature rise.
Powerful and Efficient Performance: During rated operation, the winding temperature rise, measured using the resistance method, is kept below 70K, enhancing reliability. The motor noise level is ≤50dB, ensuring user comfort during operation. With a maximum efficiency of 74.1%, the motor delivers high-performance operation.
The motor can operate smoothly and reliably for extended periods under harsh conditions such as high temperatures, low temperatures, and high altitudes, ensuring its dependability and stability.
Designed for Demanding Conditions with the Following Adaptability Features:
- Suitable for a minimum ambient temperature of -10°C, ensuring effective performance in low-temperature environments;
- Suitable for altitudes up to 2000m, enabling reliable use in high-altitude settings;
- Suitable for a maximum ambient temperature of 45°C, supporting operation in high-temperature conditions;
- Suitable for environments with a maximum humidity of 90%, ensuring reliability in humid conditions;
