2results about How to "Increase reluctance torque" patented technology

The application provides a rotor structure and a motor. The rotor structure comprises: a rotor core (1) provided with a magnetic steel slot (11); a first permanent magnet (2) installed in the magnetic steel slot (11), wherein the first permanent magnet (2) is radially magnetized; and a second permanent magnet (3) arranged at an axial end of the rotor core (1), wherein the second permanent magnet (3) is axially magnetized, and the second permanent magnet (3) comprises a plurality of polarity regions, and an included angle a between a geometric center line of one of the polarity regions and a d-axis of a polarity region adjacent to the one of the polarity regions and radially outside the one of the polarity regions and having the same polarity satisfies a >= 360° / 4p, and p is a pole pair number of the motor. According to the rotor structure, the inductance difference and the reluctance torque of the motor can be improved.
