  • Magnetically reconfigurable robot joint motor
    Patent number: 11251689
    Abstract: A magnetically reconfigurable robot joint motor includes a coil stator, a permanent magnet rotor and a magnetic reconfiguration unit. The magnetic reconfiguration unit is arranged around an outer periphery of the permanent magnet rotor, and a coil connected to a control circuit is wound on an outer layer of the magnetic reconfiguration unit. When it is necessary to execute low rotation speed or zero rotation speed operating conditions, the control circuit inputs current pulses of different strengths, so that the magnetic reconfiguration unit obtains permanent magnetization of corresponding degree, and generates a magnetic field which acts together with a magnetic field of the permanent magnet rotor, so as to maintain a torque required for output.
