An electric balance car permanent magnet motor

Abstract

The invention provides an electric self-balancing scooter permanent magnet motor, and belongs to the technical field of electric vehicles. The electric self-balancing scooter mainly comprises an outer rotor core, a stator core, a permanent magnet, an armature winding, a stator fixing block and a shaft, wherein 15 convex rotor electrodes are arranged on the outer rotor core, 4 sector-shaped sub cores are arranged on the stator core, two armature stator electrodes and a permanent magnet stator electrode are arranged on each sub core, the electrode arc length of each armature stator electrode is equal to the electrode arc length of each rotor electrode, and the electrode arc length of each permanent magnet stator electrode is equal to 1.5 times of the electrode arc length of each rotor electrode. The permanent magnet motor disclosed by the invention is provided with the 15 convex rotor electrodes which are evenly distributed and the 12 stator electrodes which are unevenly distributed, the different electrode arc mechanical angle matched relations of the stator electrodes and the rotor electrodes can enable the motor to work efficiently and stably, and the separated stator sub cores can enable the motor to have high reliability.

Description

technical field [0001] The invention relates to a permanent magnet motor of an electric balance car, belonging to the technical field of special motors. Background technique [0002] With the strengthening of people's awareness of environmental protection, the number of electric vehicles is increasing day by day. At the same time, the researchers developed a new type of electric balance car according to market demand. The electric balance car is a new type of transportation, mainly supported by two wheels, powered by a battery, and driven by a brushless motor. Life is developing in the direction of intelligence and convenience. The self-balancing vehicle conforms to this trend, conforms to the trend of the times, and has a good development prospect. [0003] As a new type of transportation, the electric balance car will inevitably have many problems. For example, when the self-balancing car stops suddenly during driving, the body is driven by inertia and falls, causing fa...
