Abstract: The present disclosure relates to a stator for an electric rotating machine, the stator comprising a stator core comprising teeth and slots, and a stator coil comprising a plurality of hairpins configured to be inserted into the slots of the stator core in a predetermined pattern. Each of the plurality of hairpins comprises a conductor and a coating layer surrounding an outer surface of the conductor. The plurality of hairpins comprise a first hairpin configured to be placed in a first section of the stator coil predetermined from an end to which power is to be input, and a second hairpin placed in a section after the first section. The first hairpin provides better insulation performance than the second hairpin, and the first section has a higher voltage distribution ratio than the section including the second hairpin.

Abstract: A laundry treating apparatus includes a tub, a drum, and a rotator. The rotator includes a bottom portion positioned on a bottom surface of the drum, a pillar protruding from the bottom portion toward an open surface of the drum, and a blade disposed on an outer circumferential surface of the pillar. The blade extends obliquely with respect to a longitudinal direction of the pillar from one end thereof facing toward the bottom portion to the other end thereof facing toward the open surface, and a first mold line at least partially extending in parallel with a circumferential direction of the pillar is formed between said one end and the other end.

Abstract: Disclosed is a laundry treating apparatus having a rotator. The rotator includes a bottom portion positioned on a bottom surface of a drum, a pillar protruding from the bottom portion toward an open surface of the drum, and a blade protruding from an outer circumferential surface of the pillar, wherein the blade extends from one end thereof facing toward the bottom surface to the other end thereof facing toward the open surface, and the blade is disposed such that said one end thereof is spaced apart from the bottom portion. As such, a washing power may be increased regardless of an amount of laundry, and a torque load of a driver may be reduced.
