4.6.2 3-phase BLDC Low Voltage Motor with Motor Brake
The Low Voltage BLDC motor-brake set incorporates a 3-phase Low
Voltage BLDC motor EM Brno SM40N and attached BLDC motor brake
SG40N. The BLDCmotor has six poles. The incremental position
encoder is coupled to the motor shaft, and position Hall sensors are
mounted between motor and brake. They allow sensing of the position if
required by the control algorithm, which is not required in this sensorless
application. Detailed motor-brake specifications are listed in
,
