The present invention discloses a motor comprising: a stator part; and a rotor assembly rotatably disposed with respect to the stator part, wherein the rotor assembly comprises: a ring magnet including an insertion hole with a shaft disposed therein and a plurality of first grooves formed at one side thereof along a first imaginary circle; and a core member including a body portion disposed between the shaft and the insertion hole, and an extension portion covering the plurality of first grooves, wherein the extension portion comprises a plurality of second grooves deviated from a plurality of first imaginary straight lines which pass from a center of the first imaginary circle respectively through the plurality of first grooves.

Rotor assembly, motor and dual clutch transmission

An embodiment relates to a stator and a motor comprising same, the stator comprising: a stator core comprising a yoke and multiple teeth protruding from the inner surface of the yoke; an insulator surrounding a part of the stator core; a coil wound around the insulator; and a molding portion disposed to cover the stator core, the insulator, and the coil. The insulator comprises a first insulator and a second insulator. The first insulator comprises: a body portion around which the coil is wound; and inner guide extending from the inside of the body portion in the perpendicular direction; a first outer guide extending from the outside of the body portion in the perpendicular direction; a second outer guide disposed to be spaced apart from the first outer guide in the outward direction; and a protrusion protruding from the second outer guide in the inward direction. The protrusion has an end portion disposed such that a predetermined gap (G) is formed between same and the first outer guide. The coil has a part disposed between the first outer guide and the second outer guide through the gap (G). Accordingly, it is possible to inhibit the coil from contacting the housing due to injection molding pressure during over-molding of the stator.

Stator and motor comprising same

The present invention provides a rotor comprising: a rotor core; a plurality of magnets disposed outside the rotor core; and a molding part disposed outside the plurality of magnets, wherein the rotor core includes a plurality of guide protrusions disposed between the plurality of magnets, and the distance from the center of the rotor core to the outer surface of the molding part passing across the center of one of the guide protrusions is shorter than the distance from the same to the outer surface of the molding part passing across the center of one of the plurality of magnets.

Rotor and motor comprising same

An embodiment relates to a motor comprising: a shaft; a rotor which is coupled to the shaft; and a stator which is disposed outside the rotor, wherein the rotor comprises a first can, a rotor core which is at least partially disposed in the first can, a plurality of magnets which are coupled to the rotor core, and a second can in which another portion of the rotor core is disposed, the plurality of magnets are spaced apart in the circumferential direction by a plurality of spacing spaces, the first can comprises a first plate portion, a first protrusion portion which is formed by bending at an edge of the first plate portion, and a plurality of first protrusions which are disposed on at least two of the plurality of spacing spaces and spaced apart from each other, the second can includes a second plate portion, a second protrusion portion which is formed by bending at the edge of the second plate portion, and a plurality of second protrusions which are disposed on at least two different spaces of the plurality of spacing spaces and spaced from each other, and the first protrusion and the second protrusion are arranged to be offset from each other.

Rotor and motor having same

A mobile terminal including a memory configured to store data; a wireless communication unit configured to perform wireless communication with a counterpart terminal; a display unit configured to display messages communicated with a counterpart of the counterpart terminal; and a controller configured to receive a selection signal selecting a first message included in the displayed messages, extract data including at least one of counterpart contact information, time information and memo information from the selected first message in response to the received selection signal, and update or add information stored in the memory of the mobile terminal using the extracted data.

Mobile terminal and controlling method thereof

A mobile terminal and method of controlling data transmission and reception therein are disclosed. In a mobile terminal selectively performing a data transceiving operation or a signal transceiving operation, the present invention includes performing the data transceiving operation, determining whether the data transceiving operation in the course of being performed meets a prior execution condition, if the data transceiving operation in the course of being performed by the wireless communication unit meets the prior execution condition, setting up a data prior mode for enabling the data transceiving operation to be performed prior to the call signal transceiving operation, wherein as the data prior mode is set up, if the call signal transceiving operation is detected, the data transceiving operation is preferentially performed. Accordingly, a data transceiving operation can be performed prior to a call signal transceiving operation despite that a hybrid mode is set.

Mobile terminal and method of controlling data transmission and reception therein

A method of executing an instant messaging service using a wireless terminal in a wireless communication system includes associating at least one user as a messenger group, activating messenger communication with a server, transmitting a messenger group status activation message to the server, receiving status data associated with the messenger group, and displaying information representing an updated status of the at least one user of the messenger group based on the status data.
