The WSB-3XX electromagnetic power-off brake is a compact, high-performance fail-safe component designed for servo and stepper motors. With a rated torque of 3N·m, 77mm housing, and 10×8.5 D shaft, this brake engages automatically when power is cut off, providing instant, secure holding torque to prevent equipment movement, making it ideal for vertical and precision applications. Constructed with high-quality copper coils, wear-resistant brake pads, and a corrosion-resistant chrome-plated housing, this brake offers long service life, low noise operation, and stable performance. The 10×8.5 D shaft design ensures a secure fit with the motor shaft, and the compact form factor allows for easy integration into robotics, medical equipment, CNC machines, and automation actuators requiring reliable power-off holding and braking.
