High-efficiency electric motor stator assembly

Abstract

An electric motor stator assembly includes a stator core and a stator winding unit disposed thereon. The stator winding unit includes a first winding and a second winding. The first winding includes a first conductor with a rectangular or square cross-section and a first rated output power. The second winding includes a second conductor with a circular cross-section and a second rated output power equal to or less than the first rated output power. During the motor's startup phase, both the first and second windings are simultaneously connected to the power supply, thereby combining their rated output power as the total output power required for motor startup. Once the motor reaches normal operating conditions, only the first winding is connected to the power supply, allowing the motor to operate at the output power of the first winding.
