The Permanent Magnet Power Off Brake is a reliable and robust braking solution designed for use with 86mm NEMA34 stepper motors. Operating on 24V DC, this brake delivers a rated torque of 4.5N·m and draws a rated current of just 0.5A, making it an efficient choice for precision motion control applications. Featuring an 8mm shaft diameter, it is engineered to fit securely onto compatible motor shafts. The working principle is straightforward: when power is cut, the permanent magnet's strong magnetic force firmly holds the iron friction plate in place, providing immediate and secure braking. When power is applied, the coil generates a magnetic field that cancels out the permanent magnet's force, allowing the friction pad to rotate freely with the shaft. This power off braking mechanism makes it ideal for emergency stopping situations. It is widely used across a range of industries, including automation equipment, chemical processing, food processing, machine tools, printing, and packaging applications.
