Problems solved by technology

Such a design structure is not only inconvenient for the miniaturization of the motor, but also because the position of the lead wire and the neutral wire and the relative position of each magnetic pole winding are unevenly distributed, and then the resistance of each phase is unbalanced, causing the relative unevenness of the current of each phase, thus affecting motor performance

Abstract

The invention provides a stator assembly, a motor, a power assembly and a vehicle, including a stator core and a stator winding. The stator core is provided with a plurality of stator slots, and the plurality of stator slots are distributed along the circumferential direction of the stator core. The winding part of each phase and one winding wire is set in the stator slot, and the leading end of each phase and one winding wire is located on the radial inner side of the winding part based on the stator core, and the leading end of each phase and one winding wire is along the circumference of the stator core. to a uniform distribution. By setting the lead-out ends on the radially inner side of the winding part and evenly distributed along the circumferential direction, the star-point ends can be arranged on the outer or inner side and can be connected in star or delta according to requirements, which not only balances the resistance of each phase, Equalizes the current in each phase, thereby improving the operational stability and related performance of the motor.

Description

technical field [0001] The present invention relates to the technical field of electric motors, and in particular, to a stator assembly, an electric motor, a power assembly and a vehicle. Background technique [0002] Because new energy vehicles do not burn gasoline or diesel to generate power, they have many characteristics such as environmental protection and low pollution, and under the vigorous promotion and application of new energy power generation such as hydropower, wind energy, solar energy and nuclear energy, many new energy vehicles are gradually being used. Promotion and application, such as new energy electric cars, new energy electric buses, new energy electric trucks, new energy electric clean vehicles, new energy electric rail vehicles, new energy electric flying vehicles, new energy electric shipping vehicles, etc. [0003] New energy vehicles are generally equipped with a battery, a motor control device, a motor and a power generation device. The power tube...
