Abstract
The invention discloses a rotor punching sheet with magnetic field sine control and quadrature axis reactance control, which comprises punching sheet bodies, a rotating shaft hole, a key groove and a plurality of grooves, wherein the grooves are arranged on the punching sheet bodies; magnetic track proportion control grooves are arranged at one sides of the grooves near an air gap in the position which is one third to one fourth of the length of the groove to the punching sheet bodies at both sides in the vertical groove direction so as to control the air gap magnetic field sine distribution effect; one sides of the punching sheet bodies, which are near the air gap, are radially provided with quadrature axis magnetic flow control grooves between two grooves and so as to change the quadrature axis magnetic circuit reluctance and control motor quadrature axis reactance; the rotor punching sheet with magnetic field sine control and quadrature axis reactance control not only has simple structure but also realizes the aim of carrying out sine control and quadrature axis reactance control by a motor magnetic field; and the harmonic distortion of the motor magnetic field is smaller than 3 percent, the quadrature axis reactance of a motor is reduced, an inner power factor angle of the motor is reduced, and the dynamic characteristics of the motor get better.
Description
Technical field
The present invention relates to a kind of motor rotor punching sheet, especially relate to the rotor punching that a kind of tool magnetic field sine controls and quadrature axis reactance controls.
Background technology
At present, common motor can not control the Sine distribution of air-gap field, causes the total harmonic distortion of motor-field higher, and the quadrature axis reactance of motor is large, the poor dynamic of motor.
Summary of the invention
The object of the present invention is to provide the rotor punching that a kind of tool magnetic field sine controls and quadrature axis reactance controls, it is simple that it has structure, can carry out the feature that sine controls and quadrature axis reactance controls to motor-field.
The object of the invention is to be achieved through the following technical solutions:
The rotor punching that a kind of tool magnetic field sine controls and quadrature axis reactance controls, it comprises punching body, shaft hole, keyway and is opened in several flute profiles on punching body, wherein, in flute profile near air gap side, be positioned at the 1/3-1/4 place of flute profile length, with vertical flute profile direction, punching body to both sides offers magnetic track proportional control groove, control air-gap field Sine distribution effect, and described punching body offers magnetic cross flux control flume near air gap side radial direction between two flute profiles, change quadrature axis magnetic circuit reluctance, motor quadrature axis reactance is controlled.
Especially, described magnetic track proportional control groove is strip.
Especially, described magnetic cross flux control flume is oval.
Beneficial effect of the present invention is, the rotor punching structure that described tool magnetic field sine controls and quadrature axis reactance controls is simple, be provided with magnetic track proportional control groove and change the feature that magnetic field distributes in " trapezoidal ", make motor-field be provided with " sine " distribution character, total harmonic distortion is less than 3%.Adopt magnetic cross flux control flume, the quadrature axis reactance of motor is diminished, the internal power factor angle of motor reduces, and the dynamic characteristic of motor improves, and adjustment groove width just can control the perunit value size of quadrature axis reactance.
