Abstract

The invention relates to an asynchronous motor with co-direction and reverse energization windings of axially adjacent sections, which includes a stator frame, a stator core, a stator winding, a rotor core, a rotor shaft, a bearing and a rotor squirrel cage winding; The stator core is fixedly arranged in the stator frame, the stator winding is fixedly arranged on the stator iron core; the rotor iron core is fixedly arranged on the rotor shaft, and the rotor shaft passes through the bearing It is fixedly arranged in the stator frame, and the rotor squirrel-cage winding is arranged on the outer circumference of the rotor core; it is characterized in that: the stator is divided into more than two sections in the axial direction, and the stator core and the stator winding are both The stator winding on the stator core in each section adopts the same direction energization coil of the axially adjacent section and the reverse energization coil of the axially adjacent section according to the energization mode, and the axially adjacent section is the same as The energized coils are powered by current in the same direction, and the axially adjacent sections of opposite energized coils are powered by reverse currents.

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...
