DC Brush motor
First let us look at the stator. As the name implies, the stator generates a stationary magnetic field that surrounds the rotor and this magnetic field is generated by either permanent magnets or electromagnetic windings.
It uses carbon brushes as the two contacts of the motor power
supply, uses speed control knobs and controllers to control, and
achieves infinite speed regulation of 0-20 km/h for electric
bicycles through secondary gear reduction and overrunning clutches.
The brushed high-speed motor used has a high gold content, strong
motor reduction gear strength, good wear resistance, and reasonable
design, resulting in a low repair rate; Moreover, the cost of
repairing and replacing gears and motors is relatively low,
effectively reducing the maintenance cost of electric bicycles; And
the brush motor can achieve easy manual cycling through the
overrunning clutch and flywheel.
Brushed motors use brush mechanical commutation.
DC brush motor is a rotating motor that contains a brush device to convert electrical energy into mechanical energy (electric motor) or mechanical energy into electrical energy (generator). Brushed motors are the foundation of all motors, with characteristics such as fast start, timely braking, smooth speed regulation over a large range, and relatively simple control circuits.
DC brush motor do not require a controller to switch current in the motor windings.
Instead, it uses a mechanical commutation of the windings. A copper sleeve ( commutator ), resides on the axle of the rotor. As the motor turns, carbon brushes slide over the commutator, coming in contact with different segments of the commutator. The segments are attached to different rotor windings, therefore, a dynamic magnetic field is generated inside the motor when a voltage is applied across the brushes of the motor. The brushes and commutator are the parts of a brushed DC motor that are most prone to wear.
