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.

With features of small size, compact structure, smooth speed
control and high cost-performance, the DK22RBL series of round
brushless motor is widely used in the advertising industry. For
example, it is used for large projectors.
