Abstract

The invention discloses a stator core assembly, a stator assembly, a motor device and a method thereof. The stator core assembly includes a plurality of core units, each core unit including a yoke portion and a tooth portion, the yoke portion extending in a first direction, the tooth portion being connected to the yoke portion and extending in a second direction, the tooth portion including a tooth tail disposed away from the yoke portion, each core unit engaging an adjacent core unit such that the plurality of core units are in a chain configuration. A stator assembly, an electric machine arrangement and a method thereof are also disclosed. According to one or more embodiments of the stator core assembly, the stator assembly, the motor device and the method thereof, the motor performance can be improved, the service life is prolonged, the application occasion is expanded, the process is simple, and cost benefits are achieved.

Description

technical field [0001] The present invention relates to the field of electric machines, and more particularly to stator core assemblies, stator assemblies, electric motor devices and methods thereof. Background technique [0002] Motor or motor refers to an electromagnetic device that realizes the conversion or transfer of electrical energy based on electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. A motor usually includes a stator and a rotor, and under the action of a magnetic field, the rotor rotates relative to the stator, thereby generating torque. [0003] Many existing motor devices or systems suffer from a number of drawbacks, such as the presence of unwanted electromagnetic noise, magnetic imbalance, and vibration, which affect the performance and application of force motors. Many existing motor devices or systems are also complicated in process, not only expensive to manufa...
