Abstract
The motor unit includes a motor and a resolver that detects a rotation angle of the motor. The motor includes a stator and a rotor disposed inward of an inner circumferential surface of a stator core and rotatably supported, and the resolver includes a resolver rotor attached to a rotor shaft that is a shaft of the rotor and configured to rotate together with the rotor shaft, and a resolver stator. The motor unit further includes a shielding plate that is made of a magnetic material and is disposed between the rotor and the resolver stator while maintaining a predetermined distance from the resolver stator.
Claims5
A motor unit comprising:
- a motor;
- and
- a resolver configured to detect a rotation angle of the motor, wherein:
- the motor includes
- a stator including a stator core and a coil attached to the stator core, and
- a rotor disposed inward of an inner circumferential surface of the stator core and rotatably supported;
- the resolver includes
- a resolver rotor attached to a rotor shaft that is a shaft of the rotor and configured to rotate together with the rotor shaft, and
- a resolver stator including a resolver stator core having an annular shape and disposed to surround an outer circumferential surface of the resolver rotor, and a resolver coil attached to the resolver stator core;
- and
- the motor unit further includes a shielding plate that is made of a magnetic material and is disposed between the rotor and the resolver stator while maintaining a predetermined distance from the resolver stator.
