Abstract

The invention relates to a motor stator for a vehicle. The stator (1) comprises a plurality of stamped and superposed silicon steel sheets (2), wherein phase grooves (3) are formed in the silicon steel sheets (2); a plurality of three-phase winding groups (4) of the stator are arranged in the phase grooves (3); hall slots (5) are reserved in the silicon steel sheets (2); hall elements (6) are placed into the hall slots (5); a hemispherical structure is adopted by the stator (1); each three-phase winding group (4) of the stator comprises a plurality of branches (9); any branch (9) is connected with an enameled coil; a center point connection end of any enameled coil is connected through a copper ring (7) coated with an insulating ring (8); and each copper ring (7) is located in the inner wall of the hemispherical stator (1).

Description

technical field [0001] The invention relates to the field of motors, and in particular provides a motor stator for automobiles. Background technique [0002] The stator in the automobile generator in the prior art includes a stator base and a winding. The stator base is provided with a cylindrical inner cavity. The inner wall of the stator base is provided with a plurality of grooves parallel to the axial direction. The windings are respectively arranged in these grooves. in the slot. The windings of some automotive generators are star-connected, and each branch in each winding is connected to a central point. In the prior art, it is relatively difficult to weld the enameled wire joint in the branch to one point, and a larger welding joint takes up more space. For example, CN203911712 separates a high-efficiency motor for electric vehicles, including a motor shaft, an inner stator is fixed in the middle of the motor shaft, an outer rotor is sleeved on the outer circumferen...
