Abstract
A tangential motor, a tangential motor rotor and a rotor core thereof are provided. The rotor core includes a rotor body and magnetic steel grooves provided on the rotor body. 2N magnetic isolation holes are provided in a rotor magnetic pole between every two adjacent magnetic steel grooves. The 2N magnetic isolation holes are symmetrically provided at two sides of a magnetic pole center line of the rotor magnetic pole. A width of each of the magnetic isolation holes increases from a circle center of the rotor body to an outer side of the rotor body. Outer side hole surfaces, close to the outer side of the rotor body, of the magnetic isolation holes are arc-shaped surfaces which are concentrically arranged with the rotor body. The rotor core is able to reduce the vibration noise of the motor and increase the efficiency of the motor.
