Permanent magnet brakes, due to their relatively small construction size, are used particularly in the MICROSTEP stepping motors of the design series SHS 39/200–xxxx.
Permanent magnet brakes are electromagnetic-ventilating brakes for dry run with non-positive, torsional-backlash-free effect, whose flux pattern is generated by permanent magnets.
The principle is based on a single planetary gearing which offers a high torque throughput with compact construction design.
- Coaxial arrangement of the input and output shaft
- Input rotation direction = Output rotation direction
- High efficiency
- Compact construction design
- Low sensitivity to impact loading
