Brushless DC Motor Series 70BL
The 70BL high speed brushless dc electric 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
- Square shape
- 3 phases
- Hall sensors
- 8 poles, Sintered NdFeB Magnets
- Rated torque up to 1.5 Nm
