Abstract

The invention discloses a motor. The motor comprises a rotatable reluctance rotor and a stator, wherein the reluctance rotor is in a closed loop shape extending in the circumferential direction of the motor; the stator comprises a plurality of stator sections arranged in the circumferential direction of the motor; the number of the stator sections is equal to or smaller than the number of stator sections connected to form the closed loop shape extending in the circumferential direction of the motor; one of the two adjacent stator sections comprises an outer winding excitation stator block located on the outer side of the reluctance rotor in the radial direction of the motor and an inner permanent magnet excitation stator block located on the inner side of the reluctance rotor in the radial direction of the motor; and the other of the two adjacent stator sections comprises an outer permanent magnet excitation stator block located on the outer side of the reluctance rotor in the radial direction of the motor and an inner winding excitation stator block located on the inner side of the reluctance rotor in the radial direction of the motor. The motor provided by an embodiment of the invention is simple and compact in structure, low in material cost, high in system efficiency, suitable for occasions of household appliances, electric vehicles, wind power generation and the like, and wide in application range.

Description

technical field [0001] The present invention relates to the technical field of motors, and more specifically, to a motor. Background technique [0002] Because the direct drive motor eliminates the transmission device, the system efficiency is effectively improved. This technology has been more and more applied to industry and life. However, the most demanding applications in the direct drive mode are low-speed and high-torque applications. Therefore, in order to increase the motor efficiency in low-speed and high-torque driving situations as much as possible, the outer diameter or axial length of the motor needs to be increased as much as possible, which will easily lead to an increase in the cost of the motor. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a motor, which has the characteristics of high torque d...
