Claims10
A motor comprising:
- a motor control circuit having a ground terminal;
- and
- a current limiting part disposed on a path electrically connecting the ground terminal and an external ground terminal included in an external circuit disposed outside the motor.
A motor comprising:
- a motor control circuit having a ground terminal;
- a current limiting part disposed on a path electrically connecting the ground terminal and an external ground terminal included in an external circuit disposed outside the motor;
- a stator and a rotor radially opposed to the stator, wherein
- the stator includes a metal housing that covers a part of the stator, and
- the metal housing is disposed on the path, wherein
- the part of the stator is electrically connected to the metal housing, and
- the motor further comprises a ferrite bead disposed on a path between the metal housing and the ground terminal;
- a stop command determination circuit that determines presence or absence of a rotation stop command for the rotor;
- and
- a switch element as the current limiting part that is controlled to be turned on and off by the stop command determination circuit.
