High-voltage motor convenient to adjust magnetic path characteristic of motor

Abstract

A high-voltage motor convenient to adjust magnetic path characteristic of a motor comprises a stator and stator grooves, wherein coils are embedded into the stator grooves, and the high-voltage motoris characterized by also comprising groove wedges, the groove wedges are arranged at groove openings of the stator grooves and are in T shapes, each groove wedge comprises a protruding tenon end and groove cover ends, the groove cover ends are arranged at two sides of the tenon and respectively extend along opposite directions, a central line of the tenon end and a connection line of the two groove cover ends are basically in an orthogonal relation, a tenon groove is formed between adjacent stator grooves in the stator, the tenon end is embedded into the tenon groove in the stator in a matching way, coil fixing in the stator grooves is jointly completed by the groove cover ends of adjacent groove wedges, a magnetic path gap is arranged between the groove cover ends of two adjacent groove wedges, a first cushion plate, a coil, a second cushion plate and thermal expansion glass felt are sequentially arranged in each stator groove. By the high-voltage motor, the surface loss and the pulsevibration loss of the motor are reduced, the motor efficiency is improved, the tenon ends of the groove wedges and the stator are closely embedded to each other, the high-voltage motor is difficult to loose and is high in limitation reliability and long in service lifetime, and vibration and noise of motor running are favorably reduced.

Description

technical field [0001] The invention relates to a motor, in particular to a high-voltage motor which is convenient for adjusting the magnetic circuit characteristics of the motor. Background technique [0002] With the increasingly wide application of medium-sized high-voltage motors and the continuous increase in the pressure to reduce the manufacturing cost of motors, reducing the loss of corresponding auxiliary materials for motors has become an important issue for all motor manufacturers. At present, the commonly used motor auxiliary materials are mainly insulating materials and slot wedges. The insulating materials are used for the insulation protection of the formed coil. fixed. Slot wedges mostly use non-magnetic slot wedges and magnetic slot wedges. The application of magnetic slot wedges has the following problems: Under the action of electromagnetic force and mechanical stress, "mechanical corrosion" or "electrical corrosion" occurs on the magnetic slot wedge, an...

AI Technical Summary

Problems solved by technology

The application of magnetic slot wedges has the following problems: Under the action of electromagnetic force and mechanical stress, "mechanical corrosion" or "electrical corrosion" occurs on the magnetic slot wedge, and there are alternating main magnetic flux and magnetic flux leakage on the magnetic slot wedge If it passes through, it will be subjected to electromagnetic pulling force in the magnetic field of the motor. This force will directly destroy the magnetic slot wedge and affect the service life of the magnetic slot wedge; it will cause the slot wedge to loosen or even fall off during the long-term operation of the motor. The phenomenon seriously affects the normal use of the motor
