STATOR, MOTOR, AND VEHICLE

WIPO Patent Application WO/2021/056853

A1

A stator, a motor, and a vehicle. The stator comprises: a stator core (1), which is provided with a plurality of stator teeth (11), the plurality of stator teeth (11) being arranged at intervals along the circumference of the stator core (1); a first coil (2), which is wound around one of the stator teeth (11), the first coil (2) comprising a first lead wire (21) and a second lead wire (22); and a second coil (3), which is wound around another stator tooth (11), the second coil (3) comprising a third lead wire (31) and a fourth lead wire (32); the second lead wire (22) extends to the third lead wire (31) and is connected to the third lead wire (31) by means of a connection part (4), such that the first coil (2) is connected in series to the second coil (3). By means of extending the second lead wire (22) of the first coil (2), the second lead wire (22) of the first coil (2) is used to serve as a bridge wire between the first coil (2) and the second coil (3). Thus, bridge wires that are additionally provided in the prior art are omitted, and operations of connecting a bridge wire to the first coil (2) are reduced, thereby improving the production and fabrication efficiency and reducing the number of connection points, which is beneficial to the improvement of connection reliability between coils.
