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
The present invention relates to a kind of crystallization kettle, particularly relate to a kind of magnetic slot wedge for motor.
Background technology
Slot wedge is commonly employed in motor, the manufacture of slot wedge also needs through various operation, in manufacturing process, usually need to carry out cutting process to slot wedge, the slot wedge of finished product is cut into the length of needs, the slot wedge length of different demand can be cause very large trouble to people, and a kind of cutting-off method easily and fast is also the problem that people need to solve simultaneously.
In view of the defect existed in above prior art, be necessary it to improve further, make it have more standby practicality, could realistic service condition.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of invention is to provide a kind of magnetic slot wedge for motor.
The present invention takes following technical scheme to realize: a kind of magnetic slot wedge for motor, comprise electric stator punching, upper stator coil, lower stator coil, arranging below stator punching is upper stator coil, middle pad is provided with in the middle of described upper stator coil and lower stator coil, heelpiece above described upper stator coil, between the bottom of described lower stator coil and expansion block, device has adjusting pad, magnetic slot-seal is provided with below described lower stator coil and electronics punching, it is rectangle that the cross section of this slot wedge of described top is rectangle bottom, and described expansion block is thermal expansion pad.
Particularly, described magnetic slot-seal top end face contacts with expansion block bottom.
Particularly, magnetic slot-seal adopts plastic optical fibre compacting to form.
The present invention has following beneficial effect in sum: the invention has the beneficial effects as follows and provide one can effectively improve magnetic potential of air gap waveform, reduce exciting curent, improve motor power factor, efficiency, reduction motor heats up, province's vibration of making an uproar, magnetic slot-seal can ensure in motor operation course, to be fixed on reliably in stator slot shape no longer occur loosening, cracking organizes loose, thus avoid because of magnetic slot-seal cracking, loose, the electric machine rotor phase sassafras produced such as come off.
