Abstract

The invention discloses a motor stator assembly for electromobiles, comprising a stationary shaft, a stator bracket and a plurality of groups of detached magnetic core units which are evenly distributed on the stator bracket and have the same structure, wherein the stator bracket is connected with the stationary shaft, each group of detached magnetic core units comprises an magnetic core block and an electromagnetism winding coil; the magnetic core block is connected with the stator bracket, and the electromagnetism winding coil is winded on the magnetic core block; the magnetic core block of each group of detached magnetic core units and the inner circle surface of an outer rotor form an air gap. Because of adopting the structure, the motor stator assembly for electromobiles of the invention can improve the working efficiency of the motor, lower energy consumption, lighten motor weight and reduce the use amount of the silicon steel sheet for a single electromobile.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor stator assembly for an electric vehicle. Background technique [0002] The existing electric vehicle motor comprises a stator assembly, a rotor frame and an outer rotor, the stator assembly has a fixed shaft, the rotor frame is composed of a first rotor bracket and a second rotor bracket, and the outer rotor is fixed on the first rotor bracket and the second rotor bracket. Between the second rotor brackets, the first rotor bracket and the second rotor bracket have central holes respectively, and the outer rings of the two bearings are respectively placed in the central holes of the first rotor bracket and the second rotor bracket, and the inner rings of the two bearings are placed in the fixed on the shaft. The stator core of the stator assembly is made of silicon steel sheet. Its structure is to open a semi-closed slot on the silicon steel sheet. After the stator winding is energi...
