Problems solved by technology

[0002] Existing drive motors for vehicles are generally AC asynchronous motors and permanent magnet synchronous motors. AC asynchronous motors are simple in structure and reliable in operation, but have low power density and narrow constant power speed regulation range. The heat generated by the rotor is transmitted to the bearing, which will greatly reduce the life of the bearing, thereby shortening the overall life of the motor; although the permanent magnet synchronous motor has high efficiency, high power density, and a wide range of constant power speed regulation, the heat generated by the rotor is relatively low....

Embodiment Construction

[0024] The concrete implementation method of the present invention is as follows:

[0025] The synchronous reluctance motor rotor provided by the present invention has multiple sets of permanent magnet slots, and each set of permanent magnet slots includes a multi-layer grid. The so-called "grid" in this article refers to the groove-like structure set on the rotor core or the structure penetrating through the rotor core in the axial direction, similar to the magnetic pole slot of the permanent magnet synchronous motor, but the grid can be filled or not filled Permanent magnet material; the so-called "saliency ratio" in this article refers to the ratio of the motor's quadrature axis inductance to the direct axis inductance. The magnetic properties of the permanent magnets in the same permanent magnet slot group of the motor rotor of the present invention are the same, and the magnetic properties of the permanent magnets between adjacent permanent magnet slot groups are opposite...

Abstract

The invention discloses a synchronous reluctance motor rotor applied to a hybrid power system. The synchronous reluctance motor rotor applied to the hybrid power system comprises a rotor core and magnetic steel. The rotor core is formed by rotor punching sheets in an overlying mode. Each rotor punching sheet comprises a plurality of symmetrical magnetic poles, and the polarities of every two adjacent magnetic poles are opposite. Each magnetic pole comprises a plurality of layers of grids, wherein the magnetic steel is placed in the grids. Grooves are formed in the excircle of the rotor in the straight axes in the direction facing the circle center of the rotor.

Description

technical field [0001] The invention relates to a synchronous reluctance motor structure, in particular to a synchronous reluctance motor rotor structure applied to a hybrid power system. Background technique [0002] Existing drive motors for vehicles are generally AC asynchronous motors and permanent magnet synchronous motors. AC asynchronous motors are simple in structure and reliable in operation, but have low power density and narrow constant power speed regulation range. The conduction of heat from the rotor to the bearing will greatly reduce the life of the bearing, thereby shortening the overall life of the motor; although the permanent magnet synchronous motor has high efficiency, high power density, and a wide range of constant power speed regulation, the heat generated by the rotor is relatively low. Low, but because it is dominated by permanent magnet torque, its counter electromotive force is too high at high speed, and loss of control will damage the system, wh...
