  • Rotor for an electric machine comprising recesses in magnet pockets
    Patent number: 9369016
    Abstract: A rotor (1) for an electric machine, in particular a permanently excited synchronous machine. At least one recess (20) is formed on the outer wall (12) of the receiving space (6) and forms a non-magnetizable space (29) adjacent to the lengthwise surface (10) of the permanent magnet (7). Due to this non-magnetizable space (29), iron losses in the stator teeth can be reduced in particular during operation of the electric machine in the field weakening range, which may result in a rise in efficacy of up to 3% for the electric machine.
    Type: Grant
