PRODUCT DETAILS

Brushless DC Motor Series 57BL NEMA23  

The 57BL 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

- Square shape

- 3 phases

- Hall sensors

- 8 poles, Sintered NdFeB Magnets

- Rated torque up to 600 mNm
