Abstract: A driving device for a washing machine includes: a shaft including an inner shaft and an outer shaft surrounding the inner shaft; a motor assembly including a stator, a rotor that surrounds the stator, a modulator that surrounds the rotor, and a magnetic gear rotating body that surrounds the modulator; a first fixation body that connects between the inner shaft and the magnetic gear rotating body; a second fixation body having one end connected to the stator and the other end connected to a tub; and an electronic clutch that disconnects the outer shat and the rotor or connects the inner shaft and the rotor according to an operation mode of the washing machine. The modulator adjusts a speed and torque of the magnetic gear rotating body. The driving device may make a motor drive area highly efficient and may reduce electric consumption.

Abstract: The present invention relates to an electronic braked-integrated in-wheel motor driving device. According to one embodiment of the present invention, an apparently complicated driving device structure, which is formed due to the installation of a brake, can be avoided, and a product appearance of a wheel-chair, to which the in-wheel motor driving device is applied, can be simplified, whereby the driving device improves the visual appearance as well as the brake function and can thus enhance production competitiveness.

Abstract: The present invention relates to a variable-flux motor comprising: a stator having stator coils; and a rotor disposed to be rotatable with respect to the stator with an air gap interposed therebetween, wherein the rotor comprises: a rotor core; a fixed magnet disposed along the radial direction of the rotor core, and of which one end portion is disposed adjacently to the air gap; and a variable magnet disposed inside the fixed magnet along the radial direction of the rotor core, and the variable magnet is formed such that a magnetic flux thereof varies when a preset current is applied to the stator coils. Therefore, use of an expensive permanent magnet can be excluded.
