Second, what is the motor
A motor is a device that converts electrical energy into mechanical energy. It uses a coiled coil (that is, a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric rotational torque. The electric motor is divided into a direct current motor and an alternating current motor according to the use of the power source. The electric motor in the electric power system is mostly an alternating current motor, and may be a synchronous motor or an asynchronous motor (the stator magnetic field speed of the motor and the rotational speed of the rotor are not kept at the synchronous speed). The motor is mainly composed of a stator and a rotor, and the direction in which the energized wire is subjected to the force in the magnetic field is related to the direction of the current and the direction of the magnetic induction line (the direction of the magnetic field). The working principle of the motor is that the magnetic field acts on the current to force the motor to rotate.
Third, the basic structure of the motor
1. The structure of a three-phase asynchronous motor consisting of a stator, a rotor and other accessories.
2. The DC motor adopts an octagonal full laminated structure and a series-excited winding, which is suitable for automatic control technology that requires forward and reverse rotation. It can also be made with series excitation winding according to user needs. The motor with a center height of 100 to 280 mm has no compensation winding, but the motor with a center height of 250 mm and 280 mm can be made with a compensation winding according to the specific conditions and needs. The motor with a center height of 315 to 450 mm has a compensation winding. The shape and technical requirements of the motor with a center height of 500-710mm are in line with IEC international standards, and the mechanical dimensional tolerances of the motor comply with ISO international standards.
Is there a difference between a motor and a motor?
The motor includes an electric motor and a generator. It is a general term for generators and motors, and the two are conceptually different. The motor is only one type of motor running mode, except that the motor runs in the electric mode, which converts the electric energy into other forms of energy; the other mode of operation of the motor is the generator, which is operated in the power generation mode and will be in other forms. The energy is converted into electrical energy. However, some motors, such as synchronous motors, are generally used as generators, but they can also be used directly as motors. Asynchronous motors are more used for electric motors, but they can also be used as generators by adding simple external components.
