An electric steel sheet is filled between the divided magnets of each of the permanent magnets of the rotor. | 06-12-2014 |
20140159540 | BOBIN AND ROTOR OF WOUND ROTOR SYNCHRONOUS MOTOR USING THE SAME - A rotor of a wound rotor synchronous motor is manufactured by forming a rotor core using a plurality of core blocks, and fitting bobbins with a coil wound onto the core blocks. In particular, the core blocks are connected such that tops of the bobbins extend from bobbin bodies and are connected with tops of other bobbins fitted on the adjacent core blocks. Additionally, a molding material may be injected into spaces between the core blocks. | 06-12-2014 |
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 |
20140184005 | ROTOR FOR DRIVE MOTOR - A rotor is provided that includes a rotor core formed in a cylindrical shape so as to be disposed and rotatable in a hollow portion of a hollow cylinder of a stator and a rotating shaft that penetrates a rotational center of the rotor core and rotates together with the rotor core accordingly. Furthermore, permanent magnets are disposed along a circumference of the rotor core and are each divided into a plurality of individual units along an axial direction of the rotor core. In particular, the plurality of individual units includes an intermediate permanent magnet positioned at a center portion in the axial direction. This intermediate permanent magnet is made of a material having coercive force higher than that of the other individual units. | 07-03-2014 |
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 |

20150103711 | METHOD FOR INTERNET PROTOCOL-BASED SLEEP MODE CONTROL USING SYNCHRONIZATION INFORMATION - A method for Internet Protocol based sleep mode control using synchronization information includes setting some of the IP-based internal hosts of a sleep mode control network to a sleep mode, providing, by a base station, a synchronization signal with respect to the overall network, thereby transferring the synchronization information of a PHY/MAC layer based on a response thereto to an internal router, and updating, by the internal router having received the synchronization information of the network layer from the base station, the state of the corresponding hosts to a sleep mode, and then transmitting, by the internal router, information about the internal hosts in a sleep mode to the external hosts of a history information list because the internal router stores the history information of the external hosts that have communicated with the internal hosts in a sleep mode in the form of a list. | 04-16-2015 |
20150103712 | INTERNET PROTOCOL-BASED SLEEP MODE CONTROL METHOD - A method for Internet Protocol (IP)-based sleep mode control is disclosed. The method includes, when a request for a sleep mode is made from any one of internal hosts, transmitting a sleep mode request message to an internal router, updating the state of the corresponding host to a sleep mode, transmitting a sleep mode ACK message to the internal host requiring a sleep mode, switching to a sleep mode, and transmitting information about the internal hosts in a sleep mode to the external hosts of a history information list because the internal router stores the history information of the external hosts that communicated with the internal hosts in a sleep mode in the form of a list. | 04-16-2015 |
