Abstract

The invention relates to an asynchronous motor with axial adjacent segment same-direction and reverse-direction power-on windings, and the motor comprises a stator seat, a stator core, a stator winding, a rotor core, a rotor shaft, a bearing, and a rotor mouse cage winding. The interior of the stator seat is fixedly provided with the stator core, and the stator winding is fixedly disposed on the stator core. The rotor core is fixedly disposed on the rotor shaft, and the rotor shaft is fixedly disposed in the stator seat through the bearing. The external periphery of the rotor core is provided with the rotor mouse cage winding. The motor is characterized in that a stator is axially divided into two segments or more; the stator core and the stator winding are respectively arranged to have two segments or more, and the stator winding of the stator core of each segment employs an axial adjacent segment same-direction power-on coil and an axial adjacent segment reverse-direction power-on coil according to a power-on mode; the axial adjacent segment same-direction power-on coil employs a same-direction current for power supply; and the axial adjacent segment reverse-direction power-one coil employs a reverse-direction current for power supply.

Description

technical field [0001] The invention relates to an asynchronous motor, in particular to an asynchronous motor with axially segmented stators and axially adjacent segments with same-direction and reverse-current energized windings. Background technique [0002] Modern society cannot do without motors, and motors are used in transportation, industrial and agricultural production, information processing, and various fields of daily life. There are many types of motors with different structures, such as asynchronous motors, permanent magnet motors, electric excitation motors, etc. All kinds of motors will generate vibration and noise during the rotation process. Vibration noise is a kind of environmental pollution, which will have adverse effects on people's health and daily life; vibration and noise are more important in the military field. Therefore, it is of great significance to reduce the vibration and noise of the motor. [0003] The fundamental magnetic field and a seri...
