Abstract
The utility model discloses a magnetic wedge for electric motor. A magnetic conductive material layer is arranged between two layers of insulation material. The insulation material layer is compression molding fiber material. The magnetic conductive material layer is molded by iron powder, benzene anhydride, quartz sand and resin. The granularity of the iron powder is 100 item. The utility model has several characteristics. The first character is energy-saving; the electric motor adopts the magnetic wedge to reduce field current and improve power factor, thereby improving efficiency by 1 to 2 percent. The second character is long life-span of the electric motor: the electric motor adopts the magnetic wedge to reduce the loss of iron core by more than 40 percent, thereby reducing temperature increase of the electric motor, electromagnetic noise and vibration. The third character is reduction of starting torque: the magnetic wedge is the magnetic conductor; therefore, the magnet leakage of the electric motor is increased and the starting torque is reduced. The fourth character is convenient mounting and maintenance: the magnetic wedge is applicable to electric motor of all openings; the mounting method is same to the bamboo wedge and epoxy cloth plate wedge; the repair is superior to the magnetic mud; once whole wedge exit or injured wedge exit can be adopted; the residue in the wedge is easy to clean out.
Description
Technical field.
The utility model relates to the slot wedge that uses on a kind of motor.
Background technology.
At present, the slot wedge that uses on motor has bamboo slot wedge and epoxy fabric swatch slot wedge, and this non magnetic slot wedge has following some shortcomings part with the motor of this non magnetic slot wedge: the one, and the empty load of motor electric current is big; The 2nd, electric machine iron core loss height; The 3rd, stator heats up high.The employing magnetic mud that also has is filled out groove, but when repairing motor, destructiveness to move back groove, and residue is difficult to clean out in groove.
The utility model content.
The purpose of this utility model is to provide a kind of whole magnetic slot-seal.
The purpose of this utility model is achieved through the following channels: a kind of magnetic slot-seal has one deck magnetic conductive material layer between the two layers of insulation material layer; Insulation material layer is the compression moulding fiber material; Magnetic conductive material layer is that iron powder, phthalic anhydride, quartz sand, mixed with resin mold pressing form; Iron particle size is 100 orders.
The utility model has following characteristics: the one, and energy-conservation, motor adopts magnetic slot-seal to reduce exciting current, improves power factor (PF), and efficient improves 1-2%; The 2nd, prolong electrical machinery life, motor adopts magnetic slot-seal, can reduce core loss more than 40%, reduces motor and heats up, and reduces electromagnetic noise and vibrations; The 3rd, reduce detent torque, because magnetic slot-seal is a magnetic conductor, the leakage field of motor is strengthened, detent torque descends to some extent; The 4th, simple installation is convenient to maintenance, and magnetic slot-seal is suitable for using on all opening motors, installation method with bamboo, epoxy fabric swatch slot wedge is identical, be better than magnetic mud during repairing, can take disposable integral to move back groove or destructiveness is moved back groove, residue is cleaned out in groove easily.
