Abstract
Provided is a field winding type motor capable of having high efficiency and reinforcing a portion having low stiffness during high speed rotation by respectively assembling metal cores in axial directions of a stator bobbin and a rotor bobbin.
Claims10
A field winding type motor comprising:
- a rotor rotatably coupled in a hollow of a housing;
- a first stator core coupled along an inner peripheral surface of the housing;
- a first rotor core coupled along an outer peripheral surface of the rotor in a state of being spaced apart from an inner peripheral surface of the first stator core;
- a bobbin assembly coupled along a gap between the first stator core and the first rotor core and generating a magnetic flux when power is applied thereto;
- a second stator core fixedly disposed on an one side of the bobbin assembly in an axial direction in a state of being coupled along the inner peripheral surface of the first stator core;
- and
- a second rotor core disposed on the other surface of the bobbin assembly so as to correspond to the second stator core and rotated together with the first rotor core when the power is applied to the bobbin assembly.
