Brushed motor
The brushed motors are one of the simplest types of motors, it is a rotating electric machine that contains a brush device that converts electrical energy into mechanical energy.
A brushed motor is a rotating electric machine that contains a brush device that converts electrical energy into mechanical energy. The brush motor is the basis of all motors. It has the characteristics of fast starting, timely braking, smooth speed regulation in a large range, and relatively simple control circuit.
Brushless motor
The brushless motor is composed of the motor body and the driver, and it runs in a self-controlled manner. Therefore, it will not add a start winding on the rotor like a synchronous motor that is started under heavy load under variable frequency speed regulation, and will not cause oscillation and loss when the load changes suddenly.
There are no brush in the brushless motor. But their design differences are more sophisticated. A brushless motor mounts its permanent magnets, usually four or more, around the perimeter of the rotor in a cross pattern. Brushless motor have four permanent magnets mounted to the top of its rotor, don’t need for connections, a commutator, and brushes.
Efficiency is a primary selling feature for BLDC motors. Because the rotor is the sole bearer of the magnets, it requires no power, no connections, no commutator, and no brushes. In place of these, the motor employs control circuitry. To detect where the rotor is at certain times, BLDC motors employ, along with controllers, rotary encoders or a Hall sensor.
