Abstract

In order to reduce the air-gap eccentricity of the horizontal motor caused by rotor gravity, a new stator core is designed and studied in this paper. The 90° area at the top of the stator core has different stator slots and coil turns from other areas. When the motor is running, an unbalanced electromagnetic force opposite to the gravity is generated in the 90° area at the top of the rotor component, so as to offset the rotor gravity to a certain extent and reduce or even eliminate the air-gap eccentricity of the motor caused by the rotor gravity. The feasibility of the design is verified by electromagnetic simulation.
