WIPO Patent Application WO/2022/179315

A1

The present invention relates to a motor, a household appliance, a gardening tool, and a vehicle. The motor comprises: a rotor core, wherein the peripheral surface of the rotor core comprises a first arc surface and a second arc surface that are alternately distributed in the circumferential direction, a first equivalent cylindrical surface is formed by taking the center of the rotor core as a first axis, the first arc surface is tangent to the first equivalent cylindrical surface, and the second arc surface deviates towards the center of the rotor core with respect to the first equivalent cylindrical surface; and a stator core, wherein the stator core is sleeved outside the rotor core; the end of a pole shoe close to the rotor core comprises a first end face, a second end face, and a third end face that are sequentially connected in the circumferential direction; a second equivalent cylindrical surface is formed by taking the first axis as an axis; the second end face is tangent to the second equivalent cylindrical surface; and both the first end face and the third end face deviate in the direction away from the center of the rotor core with respect to the second equivalent cylindrical surface. The motor is more stable in operation, vibration can be reduced, and generated vibration noise is lower.
