Permanent-magnet motor

Abstract

The embodiment of the invention discloses a permanent-magnet motor. The permanent-magnet motor comprises an annular stator structure and an annular rotor structure, wherein a stator core is provided with a plurality of stator modulation teeth, armature teeth and armature slots on an annular surface close to the rotor structure along the circumferential direction; the plurality of stator modulationteeth, armature teeth and armature slots are circularly arranged according to the order of one stator modulation tooth, one armature slot, one armature tooth and another armature slot; a first statorpermanent magnet corresponds to each armature tooth and is located at one end, close to the rotor structure, of the corresponding armature tooth; the first stator permanent magnets are magnetized along the radial direction; second stator permanent magnets are located in notches of the corresponding armature slots; the second stator permanent magnets are magnetized along the circumferential direction; and the second stator permanent magnets corresponding to two adjacent armature slots are opposite in magnetization direction; and a rotor core is alternately provided with a plurality of rotor teeth and rotor slots on the annular surface close to the stator structure along the circumferential direction. The permanent-magnet motor disclosed by the embodiment of the invention is capable of directly driving load to get rid of an intermediate transmission device in a traditional transmission system.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a permanent magnet motor. Background technique [0002] The traditional low-speed transmission system is realized by using a high-speed motor with a reduction gearbox or a belt reduction device. The existence of reduction gearbox or belt reduction device will inevitably bring many troubles, such as: low transmission efficiency, bulky, heavy equipment, noise pollution, need for lubrication, need for regular maintenance, etc. [0003] Therefore, it is necessary to manufacture a direct drive motor to directly drive the load, so as to get rid of the intermediate transmission device in the traditional transmission system and eliminate all kinds of troubles caused by the intermediate transmission device. Contents of the invention [0004] An embodiment of the present invention provides a permanent magnet motor that can directly drive a load, so as to get rid of the intermediate tr...
