Basic structure
The structure of one-phase and three-phase asynchronous motor consists of stator, rotor and other accessories.
second, the DC motor adopts octagonal fully laminated structure and series excitation winding, which is suitable for automatic control technology that needs forward and reverse rotation. According to the needs of users, it can also be made into a series winding. Motors with center height of 1 ~ 28mm have no compensation winding, but motors with center height of 25mm and 28 mm can be made with compensation winding according to specific conditions and needs, and motors with center height of 315 ~ 45 mm have compensation winding. The installation dimensions and technical requirements of the motor with a center height of 5 ~ 71 mm meet IEC international standards, and the mechanical dimension tolerance of the motor meets ISO international standards.
a Motor is a device that converts electrical energy into mechanical energy. It uses electrified coil (that is, stator winding) to generate rotating magnetic field and act on rotor (such as squirrel-cage closed aluminum frame) to form magnetoelectric rotating torque. Motors are divided into DC motors and AC motors according to different power sources. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the stator magnetic field speed of the motor does not keep synchronous with the rotor rotation speed). The motor is mainly composed of stator and rotor, and the direction of the energized conductor in the magnetic field is related to the direction of current and magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field acts on the current to make the motor rotate.
