20140305172 | MOTOR FOR WASHING MACHINE, METHOD FOR MANUFACTURING SAME, AND WASHING MACHINE HAVING SAME - Provided is a motor for a washing machine including: an inner rotor connected to a dehydrating tub rotating shaft and rotated together; an outer rotor connected to a pulsator rotating shaft and rotated together; and a double stator having a first coil arranged to leave a gap between the inner rotor and the outer rotor and which interacts with the outer rotor, to thereby form a first magnetic circuit and a second coil which interacts with the inner rotor to thereby form a second magnetic circuit, in which a first drive signal is applied to the first coil and a second drive signal different from the first drive signal is applied to the second coil. | 10-16-2014 |
20140312729 | MOTOR HAVING INTEGRAL STATOR CORE - Provided is a motor having an integral stator core, which includes: stators including a plurality of split stator cores that are annularly disposed, bobbins that are surrounded on respective outer circumferential surfaces of the stator cores, and coils wound on an outer circumferential surface of each bobbin; and rotors that are arranged with a gap from each stator, in which the stator core is integrally molded to include a yoke around which the coils are wound, and a first flange and a second flange that are formed at both ends of the yoke, and in which coil winding grooves that are formed at height lower than those of the upper and lower surfaces of the first and second flanges, are formed on the upper and lower surfaces as well as the left and right surfaces of the yoke in order to reduce height of the stator core, to thereby enable the motor to be slimmed. | 10-23-2014 |

20150303780 | STATOR HAVING THREE-LINE CONNECTION STRUCTURE, BLDC MOTOR USING SAME, AND DRIVING METHOD THEREFOR - Provided are a stator having a three-coil wiring structure, a BLDC motor using the same, and a driving method thereof, in which coils are wound by using a three-coil wiring method, to thus minimize a ratio between slots and poles, and to thereby reduce cogging noise, and a gap between cores is set small, to thus increase an effective area between a magnet and a core and to thereby reduce leakage magnetic flux. The BLDC motor includes: a stator having a plurality of split cores that are disposed between an inner rotor and an outer rotor, and on which coils of three phases are connected and wound in a three-phase drive method, in which the plurality of split cores include a number of core groups in which the coils of the respective phases are wound on three consecutive split cores in sequence of a forward direction, a reverse direction, and a forward direction, and the three consecutive split cores generate magnetic flux in opposite directions to each other. | 10-22-2015 |
