In fact, many customers are not clear about the different advantages of dc motor and ac motor. These advantages play a decisive role in choosing dc motor or ac motor.

Dc motor is a kind of motor to realize the conversion of dc electrical energy and mechanical energy. When the motor is running, it is a dc motor that converts direct current energy into mechanical energy. A generator is a direct current generator that converts mechanical energy into electrical energy. Dc motor consists of stator and rotor, with a certain air gap. The main feature of the structure is the armature of the commutator. The stator of dc motor is composed of base, main magnetic pole, commutator pole, front and rear end cover and brush frame. Main magnetic pole is the main component of air gap magnetic field of dc motor. It is composed of a permanent magnet or laminated iron core with dc excitation winding. Armature consists of two parts: armature core and armature winding. The armature core is composed of silicon steel sheets, and the groove armature windings distributed evenly on the outer circle are embedded in the groove. A commutator is a mechanical rectifier. The back piece is folded into a cylinder, and the metal clip or plastic is formed into a whole. Mutual insulation between commutators. The quality and reliability of the commutator are very important.

 

Ac motor is used to realize mechanical energy conversion and ac motor. Due to the great development of ac power system, ac motor has become the most commonly used motor. Compared with dc motor, because there is no commutator, it has simple structure, convenient manufacturing, easy to achieve high speed, high voltage, large current, large capacity. Ac motor power coverage is very large. According to its function, ac motor is usually divided into ac generator, ac motor and synchronous camera. Ac motors can also be used as generators and motors. But basically the ac motor the motor is running as a motor.
