Brushless DC Motor Series 57BLY
The 57BLY Brushless DC motor is a synchronous electric motor which is powered by direct-current electricity (DC) and which has an electronically controlled commutation system, instead of a mechanical commutation system based on brushes. In such motors, current and torque, voltage and rpm are linearly.
Motor Highlights
- Round shape
- 3 phases
- Hall sensors
- 4 poles, Bonded NdFeB Magnets
- Rated torque up to 440 mNm
