Magnetic slot wedge of motor

Abstract

The invention discloses a magnetic slot wedge of a motor. The magnetic slot wedge comprises an electric stator plate, an upper stator coil and a lower stator coil, wherein the lower surface of the stator plate is provided with the upper stator coil, a middle pad is arranged between the upper stator coil and the lower stator coil, and an upper pad is positioned at the upper surface of the upper stator coil; an adjustable pad is arranged between the bottom end of the lower stator coil and an expansion pad, magnetic slot wedges are arranged below the lower stator coil and the electric stator plate, and the sections of the slot wedges of the upper part are oblong; the sections of the slot wedges of the lower part are rectangular, and the expansion pad is a thermal expansion pad. The magnetic slot wedge of the motor is capable of effectively improving the air gap magnetomotive waveform, decreasing the magnetizing current, improving the power coefficient and efficiency of the motor and lowering the motor warming and noise vibration; the magnetic slot wedge is capable of ensuring that the motor is fixedly arranged in a stator slot without loosening and cracked tissue loosening during an operation process, so that motor stator / rotor friction generated by cracking, loosening, falling and the like of the magnetic slot wedge is avoided.

Description

technical field [0001] The invention relates to a crystallization kettle, in particular to a motor magnetic slot wedge. Background technique [0002] Slot wedges are widely used in motors, and the manufacture of slot wedges also needs to go through various processes. During the production process, it is often necessary to cut the slot wedges to cut the finished wedges into required lengths. The wedge length can cause great trouble to people, and a convenient and fast cutting method is also a problem that people need to solve. [0003] In view of the defects in the above prior art, it is necessary to further improve it to make it more practical, so as to meet the actual use conditions. Contents of the invention [0004] In order to overcome the above-mentioned defects in the prior art, the object of the invention is to provide a magnetic slot wedge for a motor. [0005] The present invention is realized by adopting the following technical proposals: a magnetic slot wedge ...
