A motor assembly includes a stator including a stator core, a stator coil, and an insulator, and a rotor. The stator core includes a yoke, a plurality of teeth, and a shoe. The insulator includes an insulator body wrapping and insulating an outer surface of the shoe so that an inner end of the shoe is exposed to outside, and a creepage distance extension portion extending a creepage distance between the stator coil and the inner end of the shoe. The creepage distance extension portion includes an inner extension section extending from the end of the shoe along the circumferential direction, and an outer extension section extending outwardly from the inner extension section. Accordingly, the creepage distances between the stator coil and the stator core in the circumferential direction and the radial direction may be increased, respectively, without increasing the size of the stator in the radial direction.

Motor assembly

An electric motor assembly includes an outer housing, an impeller rotatably disposed in the outer housing, an inner housing that is disposed in the outer housing and defines an air flow path at an outside of the inner housing, a stator disposed in the inner housing, a rotor disposed in the inner housing, the rotor comprising a rotating shaft coupled to the impeller, a first bearing that is disposed in the inner housing and supports a first side of the rotating shaft, a second bearing that disposed in the inner housing and supports a second side of the rotating shaft, and a bracket that is disposed at the second bearing and that is in contact with an end of the stator. The bracket is coupled to the inner housing in an axial direction of the inner housing.

Electric motor assembly and hair dryer having the same

A motor includes: an inner housing defining an accommodation space, an outer housing defining a flow path with the inner housing, an impeller disposed at a first side of the inner housing, a power portion that is disposed in the accommodation space and that includes a rotation shaft coupled to the impeller so as to be rotated together with the impeller, a bracket coupled to the inner housing at a second side of the inner housing and rotatably supporting the rotation shaft, and a printed circuit board (PCB) that is spaced apart from the bracket by a predetermined distance and that is electrically connected to the power portion. A circumference of the PCB includes a plurality of concave portions that are spaced apart from each other, and the plurality of concave portions are recessed toward a center of the PCB.

Motor having an impeller and a printed circuit board

An electric motor assembly includes an outer housing with two sides open, an impeller provided in the outer housing, an inner housing disposed concentrically in the outer housing and spaced apart from the impeller, a stator provided in the inner housing, a rotor rotatably disposed in the stator, a first air flow path through which air flows in an axial direction between the inner housing and the outer housing based on rotation of the impeller, and a second air flow path through which air is joined with the air of the first air flow path via an inside of the inner housing and a gap between the impeller and the inner housing based on rotation of the impeller. Accordingly, cooling of the stator can be facilitated by the air flow paths.

Electric motor assembly

An electric motor assembly for, for example, a hair dryer, includes an impeller, an outer housing in which the impeller is accommodated, an inner housing concentrically disposed in the outer housing, a stator having one side thereof accommodated in the inner housing, a rotor provided with a rotating shaft having one end coupled to the impeller and rotatably accommodated in the stator, a first bearing disposed at one side of the rotor, a second bearing disposed at another side of the rotor, and a bracket coupled to the stator and the outer housing so as to support the second bearing. Accordingly, initial alignment of the stator and the rotor may be securely maintained.

Provided are a method for transreceiving a beam reference signal or a beam refinement reference signal and transreceiving feedback information for same between a terminal and a base station in an ultra-high frequency mobile communication system, and to an apparatus for same. The method may include identifying a preferable symbol based on reference signal received power or reference signal received quality in a subframe in which the beam reference signal is received and transmitting radio resource management information or channel status information for an antenna port or an antenna array to the base station with respect to the preferable symbol.

Disclosed are a mobile device and controlling method thereof. The present invention includes a memory configured to register a first iris image, an illumination sensor configured to sense an external illuminance of the mobile device, a display configured to emit a light from a preset region, a camera configured to detect either a second iris image or a pupil image, and a controller configured to control the memory, the illumination sensor, the camera and the display and control the display to display a message for guiding a change of an eye according to the external illuminance sensed by the illumination sensor, wherein the message for guiding the change of the eye is changed according to the sensed external illuminance.

Mobile device for iris based authentication and controlling method thereof

A driver state monitoring (DSM) system includes an image obtainment apparatus configured to obtain image information of a user driving a vehicle; a biological information obtainment unit configured to be worn on a specific portion of the user's body and to obtain biological information from the specific portion of the user's body; and a controller configured to detect a dangerous driving-state in which the user drives the vehicle, based on the image information and the biological information of the user.

Driver monitoring system

The present invention relates to an autofocus device, and to a method therefor, whereby the delay necessary for auto focus can be reduced according to circumstances and a clear image of a subject can be obtained in a timely fashion by suitably adjusting the precision and speed of autofocus, as auto focus settings are differently applied in accordance with the photography mode when autofocus is being implemented in a camera. To this end, the autofocus method according to an embodiment of the present invention comprises: a step of inputting a photography mode for a subject; a step of deciding which auto focus setting corresponds to the input photography mode; a step of determining the lens step with the highest focal value among lens steps set according to the distance of the subject and the lens on the basis of the auto focus setting decided upon; and a step of moving the lens to the determined lens step.
