Embodiment Construction

[0014] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0015] Such as figure 1 with figure 2 As shown, the rotor of the electric excitation double salient pole motor of the present invention includes a rotor central shaft 4, a rotor iron core 3, a rotor punching piece 2, and a rotor core filling block 5. The rotor iron core 3 is located at the outer ring of the rotor central axis 4, and the rotor punching piece 2 is located on the periphery of the rotor core 3, and the rotor core filling block 5 is fixed on both ends of the rotor punch 2 with rivets 1.

[0016] The material of the rotor iron core filling block 5 is polytetrafluoroethylene, and the cost of this material is the lowest. A layer of insulating varnish is coated on the periphery of the rivet 1, and the insulating varnish plays an insulating role to prevent the surface of the ro...

Abstract

The invention discloses an electro-magnetic dual-salient-pole motor rotor which includes a rotor center shaft, a rotor iron core, rotor stamped sheets, and rotor iron core filling blocks. The rotor iron core is located at the outer ring of the rotor center shaft. The rotor stamped sheets are located at the periphery of the rotor iron core. The iron core filling blocks are fixed at the two ends of the rotor stamped sheets through rivets. The electro-magnetic dual-salient-pole motor rotor is applicable to a normal operating work condition of a high-speed large-power electro-magnetic dual-salient-pole motor so as to improve the stability, security and operating performance of the motor.

Description

technical field [0001] The invention relates to an iron core design seat, in particular to an electrically excited double salient pole motor rotor. Background technique [0002] Electric excitation doubly salient motor is a new type of product developed on the basis of switched reluctance motor. It has significant advantages such as high stability, low cost, simple process and suitable for high temperature operation. Because the motor is running at a normal high speed, the centripetal force generated due to the high linear speed of the rotor is also relatively large, which will cause accidents such as rotor breakage and motor burnout. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric excitation double salient pole motor rotor, which is suitable for the normal operation and working conditions of the high speed and high power electric excitation double salient pole motor, so as to improve and improve the ...
