20140167535 | MOTOR UNIT HAVING COOLING CHANNEL - A motor unit for a vehicle is provided with a cooling channel cooling channel formed within a motor housing of the motor unit, and forming a flow channel that allows coolant to flow through the flow channel. The cooling channel includes: a supply channel portion having an inlet; an exhaust channel portion having an outlet; and a flow channel changing portion connecting the supply channel portion and the exhaust channel portion to allow a coolant supplied through the inlet of the supply channel portion to be discharged through the outlet of the exhaust channel portion, where at least one of inner protrusion portions and outer protrusion portions are formed on an inner circumferential surface and an outer circumferential surface, respectively, of the supply channel portion or the exhaust channel portion, protruding toward the motor shaft, and extending in a circumferential direction. | 06-19-2014 |
20140184013 | STATOR FOR SYNCHRONOUS MOTOR - A stator for a motor that includes an armature coil that generates an N-pole and an S-pole by applying a current and forty-eight slots radially formed at which the coil is disposed and in which the armature coil alternately implements N-poles and S-poles by arranging six slots as a single unit as the current is applied to the coil. The slot includes a plurality of phase drawing out slots, and when the order of the phase drawing out slots is determined in a clockwise direction by setting one phase drawing out slot as a first phase drawing out slot, at least two methods of winding the armature coil to turn around the slot may be used to decrease a distance from the first phase drawing out slot to the last phase drawing out slot to a minimum value by setting a cell between neighboring slots as a unit. | 07-03-2014 |
20140184014 | STATOR BOBBIN FOR DRIVE MOTOR - In a stator bobbin for a drive motor, a bobbin body is coupled to a stator core divided into a number of sections across an entire area of the stator, and a coil is wound on the bobbin body. The trailing portion of the coil wound on the bobbin body is fixed to a fixing slot formed at one side of the bobbin body. | 07-03-2014 |
20140327345 | NOISE SHIELD UNIT IN WOUND ROTOR SYNCHRONOUS MOTOR (WRSM) MOTOR - A noise shield unit in a WRSM drive motor has a rotor wound with coils with a slip ring disposed thereon. A brush is mounted to a brush holder to be in contact with the slip ring, and a position sensor is mounted to an end portion of the rotor. The noise shield unit may include a shield plate of a magnetic material mounted between the brush holder and the position sensor. | 11-06-2014 |
20140339952 | ROTOR STRUCTURE OF DRIVE MOTOR - A rotor structure of a drive motor is provided. In the rotor structure of a driving motor, a rotor core is divisionally formed in a plurality of core blocks and the core blocks may be combined around an outer side of a rotary shaft. | 11-20-2014 |
20150077099 | STRUCTURE OF MEASURING IRON LOSS OF MOTOR STATOR CORE - A structure for measuring iron loss of a motor stator core is provided. The structure includes an auxiliary core whose both end surfaces in a longitudinal direction come in contact with inner end surfaces of two adjacent stator teeth among a plurality of stator teeth in a radial direction in order to measure iron loss of a stator core in which a plurality of slots and the plurality of stator teeth are alternately formed on an inner circumferential surface of a stator yoke in a circumferential direction. A pair of excitation windings is provided at portions of the auxiliary core in the longitudinal direction spaced-apart from each other. A B-coil that is a sensor coil is provided at the auxiliary core so as to be positioned inside any one excitation winding of the pair of excitation windings. Fixing protrusions protrude from the both end surfaces of the auxiliary core to extend in the longitudinal direction, and inserted into the slot between the two adjacent stator teeth to be fitted and fixed in the circumferential direction. Accordingly, it is possible to quantitatively and accurately measure iron loss of the motor stator core for each manufacturing process. | 03-19-2015 |
