Abstract
A motor may include a shield member that screens a magnetic field between a stator and a rotor, and a moving member that controls a position of the shield member in response to an electromagnetic interaction with the stator such that the screening of the magnetic field is configured to be selectively performed. The motor may prevent a generation of a counter electromotive force or regenerative braking.
Claims18
A motor comprising:
- a stator;
- a rotor configured to rotate inside the stator in response to a first electromagnetic interaction with the stator;
- a shield member comprising a plurality of shield elements configured to screen a magnetic field between the stator and the rotor;
- and
- a moving member configured to control a position of the shield member in response to a second electromagnetic interaction with the stator such that screening of the magnetic field is configured to be selectively performed,
- wherein the moving member comprises:
- a support element configured to integrally rotate with the shield member,
- a magnetic element disposed on the support element, and rotating the support element in a first direction in response to the second electromagnetic interaction with the stator, and
- an elastic element disposed on the support element, and rotating the support element in a second direction opposite to the first direction in response to a compression restoring force.
