Technical Field

[0001] The utility model relates to the technical field of motor windings, in particular to an aluminum wire motor stator winding. Background Art

[0002] The stator windings of traditional motors are made of round enameled copper wire. Copper wire has a high specific gravity, which increases the overall weight of the motor. Furthermore, when winding round wire, the wires cannot be wound tightly together, resulting in large gaps between the wires. This results in low slot utilization in the stator core.

[0003] Existing motors use aluminum wire windings, which greatly reduces the cost of the motor. However, the thermal stability of aluminum wire windings may not be as good as that of copper wire windings, and the performance of aluminum wire may deteriorate at high temperatures.
