摘要: A synchronous reluctance motor is described. The synchronous reluctance motor includes a core configured to rotate about a central axis and having first and second groups of flux barriers formed therein. Each flux barrier is defined as an opening in the core. Each of the first and second groups includes a first flux barrier and a second flux barrier with the second flux barrier disposed outside the first flux barrier in a radial direction from the central axis of the core. Each of the second flux barriers of the first and second groups has at least two connection parts crossing the opening of the second flux barrier.

摘要: A power brush assembly for vacuum cleaners is disclosed. In the power brush assembly, a casing is set in the suction part of a vacuum cleaner and defines a suction nozzle used for sucking dust-laden air under pressure into the suction part of the vacuum cleaner. A power brush is set within the casing such that the brush is rotatable and reciprocable to the left and right. This power brush is used for brushing dust and impurities on a target surface. A drive motor generates a rotating force for allowing the power brush to rotate and reciprocate to the left and right within the casing. A power transmission mechanism connects the drive motor to the power brush so as to transmit the rotating force of the drive motor to the power brush. In this power brush assembly, the brush body of the power brush performs a linear reciprocating action in addition to a rotating action, and so the brush assembly effectively and actively brushes a target surface at areas corresponding to the gaps between opposite ends of the brush body and opposite sidewalls of the casing. This brush assembly thus improves the dust cleaning effect of a vacuum cleaner.

摘要: A washing machine, with an inner tub designed to be linearly reciprocable along its vertical axis in addition to being rotatable on the vertical axis during the washing or rinsing process, is disclosed. In the washing machine, a washing tub is suspended within a cabinet forming the profile of the washing machine and having an openable cover at its top end. The washing tub consists of an outer tub suspended within the cabinet and containing water therein, and a perforated inner tub set within the outer tub. This inner tub contains laundries therein, and washes or rinses the laundries during the washing or rinsing process. A drive unit is mounted to the bottom of the outer tub, and rotates and vertically reciprocates the inner tub within a predetermined stroke. The washing machine of this invention thus forms vertical moving currents of water in addition to active swirling currents of water within the inner tub, and prevents laundries from being twisted during the washing or rinsing process. The washing machine is also improved in its rinsing and detergent dissolving performance, and is improved in its overall laundering effect.

摘要: A clutch apparatus of a washing machine is provided. The clutch apparatus includes a coupling unit comprising a magnetic unit at least in one part, combined around the basket shaft, and combined with a rotor of the driving motor in a state where the coupling unit moves downward, the coupling unit for transmitting the rotary power of the driving motor to the basket shaft and a solenoid actuator comprising a solenoid coil and fixed to the lower portion of the tub, the solenoid actuator for supplying electromagnetic repulsive force between the solenoid actuator and the coupling unit so that the coupling unit is separated from the rotor of the driving motor, to thus push the coupling unit upward. The clutch apparatus is formed to have a repulsive type structure unlike a conventional attractive type clutch apparatus. Accordingly, it is possible to collision noise generated when the coupling unit rises and to reduce the amount of consumption of power for maintaining a state where the coupling member rises.
