Abstract
The utility model discloses a rotor punching plate with magnetic field sine control and quadrature axis reactance control. The rotor punching plate comprises a punching plate body, a rotating shaft hole, a key slot and a plurality of groove shapes arranged on the punching plate body. A magnetic track proportional control slot is arranged toward the punching plate body of two sides at 1/3-1/4 position of the groove shape length at one side of the groove shape close to an air gap in a direction vertical to the groove shape, so as to control the sine distribution effect of an air gap field. The punching plate body is radially provided with a quadrature axis flux control slot at one side adjoining the air gap between two groove shapes, so as to change the magnetic circuit and resistance of a quadrature axis and control the quadrature axis reactance of a motor. The rotor punching plate with the magnetic field sine control and the quadrature axis reactance control not only has a simple structure, but also realizes the sine control and the quadrature axis reactance control in the magnetic field of the motor. The harmonic distortion degree of the magnetic field of the motor is lower than 3%, therefore, the quadrature axis reactance of the motor is smaller, the internal power factor angle of the motor is reduced and the dynamic characteristic of the motor becomes better.
Description
Technical field
The utility model relates to a kind of motor rotor punching sheet, especially relates to the rotor punching of sinusoidal control in a kind of tool magnetic field and quadrature axis reactance control.
Background technology
At present, common motor can not be controlled the Sine distribution of air-gap field, cause the total harmonic distortion of motor-field higher, and the quadrature axis reactance of motor is big, and the dynamic characteristic of motor is poor.
The utility model content
The purpose of this utility model is to provide the rotor punching of sinusoidal control in a kind of tool magnetic field and quadrature axis reactance control, and it has simple in structure, can carry out the characteristics of sinusoidal control and quadrature axis reactance control to motor-field.
The purpose of this utility model is to be achieved through the following technical solutions:
The rotor punching of sinusoidal control in a kind of tool magnetic field and quadrature axis reactance control, it comprises punching body, shaft hole, keyway and is opened in several flute profiles on the punching body, wherein, in close air gap one side of flute profile, 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 between two flute profiles, radially offer the magnetic cross flux control flume on the described punching body near air gap one side, change and hand over axle magnetic circuit magnetic resistance, the motor quadrature axis reactance is controlled.
Especially, described magnetic track proportional control groove is a strip.
Especially, described magnetic cross flux control flume is oval.
The beneficial effects of the utility model are, the rotor punching of sinusoidal control in described tool magnetic field and quadrature axis reactance control is simple in structure, be provided with magnetic track proportional control groove and changed the feature that magnetic field is " trapezoidal " distribution, make motor-field have " sine " distribution character, total harmonic distortion is less than 3%.Adopt the 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 adjusts the perunit value size of groove width with regard to the may command quadrature axis reactance.
