Motor rotor punching sheet and synchronous reluctance motor

Abstract

The invention provides a motor rotor punching sheet and a synchronous reluctance motor. The motor rotor punching sheet comprises a punching sheet body (1), wherein the punching sheet body (1) comprises a plurality of magnetic barrier groups which are arranged along the circumferential direction; each magnetic barrier group comprises magnetic flux barriers (2) which are arranged at intervals alongthe radial direction, magnetic conduction channels (3) are formed between the adjacent magnetic flux barriers (2) under the same pole, each magnetic flux barrier (2) comprises a first part (4) and a second part (5) in a plane perpendicular to the central axis of the punching sheet body (1), the first part (4) is perpendicular to the Q-axis, and the second part (5) is bent outwards in the radial direction relative to the first part (4). According to the motor rotor punching sheet, the rotor reluctance torque can be effectively increased, and the operation efficiency of the motor is improved.

Description

technical field [0001] The present application relates to the field of motor technology, in particular to a motor rotor stamping and a synchronous reluctance motor. Background technique [0002] With the rapid development of modern society, how to save energy and resources has become an important consideration for the future development direction of all walks of life. Motors are an important component of modern society. The annual power consumption of motors accounts for more than 30% of the electricity consumption of human society. High-efficiency permanent magnet synchronous motors need to use rare resources and rare earth metals. It is difficult for asynchronous motors that mainly use conventional materials to achieve greater energy efficiency. breakthrough. [0003] The synchronous reluctance motor is a feasible solution because the rotor only needs to process various groove shapes with silicon steel sheets without adding any filling. The efficiency of synchronous relu...
