Compact Structure Mini Brushless DC Motor 22mm Round For Large Projectors
22mm Round Brushless dc motor using for Advertising Instrument
A 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 related.
