1, X structure and principle is different: brush motor is a more traditional type of motor, mainly by the stator, rotor, commutator and brush and other parts. Its working principle is through the brush and commutator contact, realize the current commutation, so as to drive the rotor rotation. Brushless motor is a new type of motor, mainly composed of stator, rotor and electronic commutator. Its working principle is to realize the current commutation through the electronic commutator, so as to drive the rotor to rotate. Compared with brushed motors, brushless motors have a simpler structure and are easier to maintain.
2, the application of different areas: brush motors, due to its lower cost, simple structure, easy to maintain and so on, brush motors are widely used in many areas, such as electric bicycles, electric tools, household appliances. Brushless motors, on the other hand, are widely used in high-end equipment and precision instruments, such as aerospace, medical equipment, industrial automation, etc., due to their high efficiency, long life and low noise.
3, motor (commonly known as "motor") refers to the law of electromagnetic induction to realize the conversion or transmission of electrical energy, a kind of electromagnetic device. Divided into electric motors (symbolized by M) and generators (symbolized by G).
