WIPO Patent Application WO/2024/007709

Kind Code:

A1

Abstract:

The present invention provides a stator, a flat wire motor, a power assembly, and a vehicle. The stator comprises: a stator iron core, the inner wall of the stator iron core being provided with s stator slots; and a stator winding comprising three phases of windings, each phase of winding comprising b parallel branches, and each parallel branch comprising a plurality of hair-pin coils connected by a connecting wire; wherein the plurality of hair-pin coils comprise a third hair-pin coil having a pitch of s/(2p)+a, a first hair-pin coil having a pitch of s/(2p), and a second hair-pin coil having a pitch of s/(2p)+a-4, and a is an integer greater than or equal to 2 and less than or equal to 4; in each parallel branch, a first support leg and a second support leg of the second hair-pin coil are respectively located in a kth slot layer and a (k+1)th slot layer, a first support leg and a second support leg of the third hair-pin coil are respectively located in the (k+1)th slot layer and a (k+2)th slot layer, and a first support leg and a second support leg of the first hair-pin coil are both distributed on a first slot layer or an nth slot layer. In this way, according to the stator provided by the present invention, the manufacturing costs of stators can be reduced.
