Abstract

The invention discloses a flat wire winding structure and a stator and a motor comprising the flat wire winding structure, the flat wire winding structure is arranged in a stator core, a tooth part of the stator core is provided with a plurality of wire slots, each wire slot is provided with an even number of mounting positions which are arranged in the radial direction and are used for accommodating pins of a plurality of flat wire coil conductors, and the flat wire winding structure is arranged in the stator core. Wherein the flat wire winding structure comprises a first phase winding, a second phase winding and a third phase winding, each phase winding comprises four parallel branches, and the first phase winding, the second phase winding and the third phase winding are each of a double-layer winding structure; and in a circle of winding around the stator core, each parallel branch is led in from the upper layer of one wire slot and led out from the lower layer of the other wire slot, and the two different parallel branches of the same-phase winding are overlapped in the wire slots to form the double-layer winding structure. The motor disclosed by the invention has relatively good torque output performance and relatively high power factor.

Description

technical field [0001] The invention relates to the field of motors in electric vehicles, in particular to a flat wire winding structure, a stator and a motor including the same. Background technique [0002] With the development of electric vehicle technology, its requirements for the running performance of the drive motor are getting higher and higher. As a key component of an electric vehicle, the output performance of the drive motor directly affects the efficient operation of the whole machine. [0003] Compared with the traditional round wire motor, the current flat wire motor has the advantages of higher slot full rate, better temperature performance and wider high efficiency area. The number of square conductors in the core slot is generally 2, 4 or 8, and the number of parallel branches is generally 1 or 2. [0004] A four-way parallel type flat wire motor winding structure in the prior art, which reduces the high-speed skin effect of conductors by increasing the ...
