Abstract
The present disclosure relates to an electronic clutch-coupled motor assembly and a driving device for a washing machine having the same. The electronic clutch-coupled motor assembly includes a motor including a stator defining a space having a predetermined size at an inner center thereof and a rotor spaced a predetermined distance from an outer circumference of the stator, disposed to surround the stator and configured to rotate, and an electronic clutch including an electronic clutch insert core having a circular shape and an electronic clutch bobbin fixed and coupled to an inside of the electronic clutch insert core, and press-fitted and coupled to the stator through the space and integrated with the stator.
Claims20
An electronic clutch-coupled motor assembly, comprising:
- a motor comprising:
- a stator that defines an inner space at a center of the stator, and
- a rotor that surrounds the stator and is spaced apart from an outer circumference of the stator, the rotor being configured to rotate relative to the stator;
- and
- an electronic clutch that is inserted into and coupled to the stator through the inner space of the stator, the electronic clutch comprising:
- an electronic clutch insert core having a circular shape, and
- an electronic clutch bobbin coupled to an inside of the electronic clutch insert core.
A driving device for a washing machine, the driving device comprising:
- a motor comprising:
- a stator that defines an inner space at a center of the stator, and
- a rotor that surrounds the stator and is spaced apart from an outer circumference of the stator, the rotor being configured to rotate relative to the stator;
- an electronic clutch that is press-fitted into and coupled to the stator through the inner space, the electronic clutch comprising:
- an electronic clutch insert core having a circular shape, and
- an electronic clutch bobbin coupled to an inside of the electronic clutch insert core;
- a sun gear shaft configured to receive rotational force from the motor and to rotate based on the rotational force from the motor;
- a sun gear coupled to an upper end of the sun gear shaft;
- a plurality of planetary gears that surround an outside of the sun gear;
- and
- a planetary gear shaft configured to receive rotational force from the plurality of planetary gears and to rotate based on the rotational force from the plurality of planetary gears.
