Title:
MOTOR, COMPRESSOR, AND FAN
Document Type and Number:
WIPO Patent Application WO/2022/217824
Kind Code:
A1
Abstract:
A motor, a compressor, and a fan. The motor (8) comprises a rotor core (4), rotor slots, and a stator core (1). The rotor slots are arranged through the rotor core (4), and the rotor slots are inclined with respect to the axial direction. The stator core (1) is disposed on one side of the rotor core (4). The stator core (1) comprises stator teeth (10) facing the rotor core (4), air gaps (13) are provided between the stator teeth (10) and the rotor core (4), and at least some of the air gap (13) are not equal. Inclined rotor slots are provided on the rotor core, and air gaps that are not completely equal or completely unequal are formed between the stator teeth and the rotor core, so as to satisfy the requirements of reducing the low-speed harmonic torque fluctuation and improving the output performance of the motor, so that the starting additional torque and rated performance of the motor can be matched with each other.
