Abstract

The invention discloses a brushless hybrid excitation motor for an electric skateboard, which belongs to the technical field of electric vehicles. The brushless hybrid excitation motor for the electric skateboard is composed of a shaft, a hub, a stator iron core, armature windings, permanent magnets, a rotor iron core and a bearing, wherein the inner circumference of the hub is fixed with 4K rotorteeth, and K is a positive integer; the stator iron core is formed by 3K uniformly-distributed [-shaped sub stator iron cores, and two sides of each sub stator iron core are provided with stator teeth; all stator teeth face the outer side of the circumference, and the two stator teeth of the same sub stator iron core are arranged at two sides of the rotor tooth of the rotor iron core; the middleyoke part of each sub stator iron core is embedded with the permanent magnet; and the middle yoke part of each sub stator iron core is wound with a centralized armature winding. Centralized excitationcan be effectively realized, the magnetic path is short, and iron and copper consumption is little; the advantage of high power density of a disc motor can be thoroughly exerted, and high applicationvalue is realized in the micro electric vehicle such as the electric skateboard.

Description

Technical field [0001] The invention relates to a brushless hybrid excitation motor for an electric skateboard, belonging to the technical field of electric vehicles. Background technique [0002] Electric scooter is another new product form of skateboarding after traditional skateboarding. Electric scooters are very energy-saving, fast charging and long range capability. The vehicle has beautiful appearance, convenient operation and safer driving. As a pollution-free green and environmentally friendly transportation product, electric scooters are increasingly being valued by enterprises. [0003] The electric motor is an important part of the electric scooter, and the performance of the drive system affects the performance of the electric scooter. From the currently disclosed technology, most common motors for electric skateboards are hub motors. Among the similar patents, such as the patent application with the application number of 201610717416.4: a hub motor applied to elec...
