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.
