What Are The Types Of Commonly Used Motors? The Characteristics Of Different Types Of Motors
1. DC motor A DC motor generates a magnetic field by winding an excitation coil on the main magnetic pole of the stator and applying direct current to it. The armature winding of the rotor is also connected to direct current. The energized winding is placed in the magnetic field to output electromagnetic torque to drive the load. It is used in energy vehicles, and it is basically not used in new models. Advantages︰ 1. Good control performance 2. The speed is easy to adjust 3. Mature technology 4. Low cost Disadvantages: 1. The converter and the brush are independent, and the speed is not improved well 2. The brush is prone to failure 3. High maintenance costs 2. Asynchronous AC motor Three-phase alternating current is input into the stator windings, and the excitation current in the stator windings generates a rotating magnetic field in the stator core. At this time, the induced current in the rotor windings passes and pushes the rotor to rotate. Although this kind of motor is fast, bu...
