Patent ID: 10630124

Abstract:
The invention discloses an electric motor and a tangential type permanent magnet rotor. The tangential type permanent magnet rotor includes a rotor iron core (2) and permanent magnets (1) provided on the rotor iron core (2); a width of one side, close to the outer edge of the rotor iron core (2), of each of the permanent magnets (1) is H2; and a width of one side, close to the center of the rotor iron core (2), of each of the permanent magnets (1) is H1, wherein H2>H1. The tangential type permanent magnet rotor enables the width H2 of a permanent magnet part close to the outer edge of the rotor iron core to be larger, and enables the width H1 of a permanent magnet part close to the center of the rotor iron core to be smaller.
