What Is A Brushless Motor
- Dec 13, 2018 -

The brushless DC motor is controlled by the speed controller and the controller, and the stepless speed regulation of the electric bicycle is 0-20 km/hour through the gear secondary deceleration and the overrunning clutch. The high-speed motor currently used has high gold content, strong motor reduction gear strength, good wear resistance, reasonable design, so the repair rate is low; and the cost of repairing and replacing gears and motors is less, effectively reducing the maintenance of electric bicycles. Cost; and brushed motors can be easily manned by overrunning clutches and flywheels. Brushed motors are mechanically commutated by brush.

A brushless motor refers to a brushless DC motor consisting of an electric motor, its main body and a driver. It is a typical mechatronic product. Since the brushless DC motor is operated in a self-controlled manner, the starting winding is not added to the rotor like the synchronous motor with heavy-load starting under the variable frequency speed regulation, and the oscillation and the out-of-step are not generated when the load is abrupt. The permanent magnets of the medium and small capacity brushless DC motors are now mostly made of rare earth neodymium iron boron materials with high magnetic energy products. Therefore, the volume of the rare earth permanent magnet brushless motor is reduced by one frame number compared with the same capacity three-phase asynchronous motor.
