Problems solved by technology

[0002] The permanent magnet synchronous motor is equipped with permanent magnets on the rotor, and its structure is evenly distributed on the outside of the rotor. The rotor of the synchronous reluctance motor is distributed with closed slots, and there is no need to install permanent magnets, resulting in a lower power density of the motor and a smaller volume of the motor. Large, poor starting performance, for this reason, we propose a synchronous reluctance permanent magnet motor rotor structure

Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0012] like figure 1 As shown, a synchronous reluctance permanent magnet motor rotor structure includes a permanent magnet 1, a salient pole 2, a punching plate closed slot 3, a magnetic steel slot 4, a rotor 5 and a housing 6, and the inner side of the housing 6 is provided with a punching The sheet closed slots 3, the magnetic steel slots 4 are arranged between the punched sheet closed slots 3, the housing 6 is provided with a rotor 5 and the rotor 5 is provided with a permanent magnet 1.

[0013] Wherein, a salient pole 2 is provided outside the rotor 5 and the salient pole 2 is located in the axial direction of the rotor 5 .

[0014] In this example, if figure 1 As shown, the salient pole 2 can better increase the difference between the d-ax...

Abstract

The invention discloses a synchronous reluctance permanent magnet motor rotor structure. The structure comprises a permanent magnet, a salient pole, punching sheet closed grooves, magnetic steel grooves, a rotor and a shell, the punching sheet closed grooves are formed in the inner side of the shell, the magnetic steel grooves are formed between the punching sheet closed grooves, the rotor is arranged in the shell, and the permanent magnet is arranged in the rotor. According to the invention, the permanent magnet is placed in the rotor, and the salient pole is added in the axial direction of the rotor to better increase the difference between the d-axis inductance and the q-axis inductance, so that the reluctance torque of the motor is more effectively improved, the power density of the motor is higher, the size of the motor is reduced, the starting performance of the motor is better, and the motor is suitable for wide popularization and application.

Description

technical field [0001] The invention relates to the technical field of motor structure, in particular to a synchronous reluctance permanent magnet motor rotor structure. Background technique [0002] The permanent magnet synchronous motor is equipped with permanent magnets on the rotor, and its structure is evenly distributed on the outside of the rotor. The rotor of the synchronous reluctance motor is distributed with closed slots, and there is no need to install permanent magnets, resulting in a lower power density of the motor and a smaller volume of the motor. Large, poor starting performance, for this reason, we propose a synchronous reluctance permanent magnet motor rotor structure. Contents of the invention [0003] The main purpose of the present invention is to provide a synchronous reluctance permanent magnet motor rotor structure, by putting permanent magnets into the rotor, a salient pole is added in the axial direction of the rotor, and its function is to bett...
