PROBLEM TO BE SOLVED: To provide a PM stepping motor with a claw pole capable of reducing the outside diameter size . SOLUTION: A PM stepping is configured such that a first motor segment 300 and a second motor segment 400 are arranged in a symmetrical structure to form a module corresponding to a first pole teeth segment 520 and a second pole teeth segment 530 provided so as to face a main yoke member 500, respectively, which are incorporated so as to substantially divide into two halves the interior of a housing 100, into which a rotation shaft 200 is penetrated and supported in a rotatable state. The first motor segment 300 and the second motor segment 400 include magnet rotors 310, 410, and auxiliary yoke members 320, 420, and coil bobbins 340, 440, arranged on the same shaft so as to produce mutual electromagnetic force, respectively. With such a configuration, the coil bobbins are provided on the same shaft remaining to be separated from each other at a predetermined spacing, the outside diameter size of a motor can be further reduced, as compared with a structure in which the coil bobbins are arranged concentrically.

Abstract:
A rotary actuating device having a unit for compensating a friction force is provided to control actuating force to rotate a rotary plate by increasing or decreasing an amount of the friction force of each micro moving unit for the rotary plate. A rotary actuating device having a unit for compensating a friction force includes a base(100), a rotary plate(110), a plurality of micro moving units(120), a variable supporting unit(130), and a supporting plate(131). The base(100) is a plate type, supports other components, and forms a lower part of the rotary actuating device. The rotary plate(110) is rotatably installed on an upper part of the base(100). The plurality of micro moving units(120) are installed on a lower plane of the rotary plate(110). The variable supporting unit(130) supports the plurality of micro moving units(120) and controls for each micro moving unit to have uniform friction force for the rotary plate(110). The supporting plate(131) has an upper plane where the plurality of micro moving units(120) are installed and includes through holes(131a) upward and downward on at least three points thereof.
Abstract:
A motor assembly for driving the blower of a fuel cell system is provided to absorb and inhibit the vibration of a rotation axis due to high speed rotation, thereby stabilizing the operation of a blower. A motor assembly for driving the blower of a fuel cell system comprises a hollow cylinder-shaped fixed cover(100); a stator core(110) installed at the outer circumference of the fixed cover and having a wound coil; a rotation axis(120) so as to inserted into the hollow of the fixed cover; a first bearing(141) inserted into the one end of the hollow of the fixed cover to support the rotation axis; a second bearing(142) inserted into the other end of the hollow of the fixed cover to support the rotation axis; an elastic member compressing the first bearing to the one end of the hollow; a rotation cover(130) having a penetration hole where the one end of the rotation axis is inserted and surrounding the core; a permanent magnet(170) fixed so as to face with the core each other at the rotation cover; a hole sensor(180) sensing the rotation displacement of the permanent magnet; and a control board(200) for controlling the power applied to the coil of the stator core according to the rotation displacement.
Abstract:
A method and system for providing a Network-based User Interface (NUI) is provided. The method for providing the NUI includes: selecting one from among devices connected to a network; acquiring a UI regarding the selected device through the network; and interacting with the device by using the acquired UI. Accordingly, the user terminal can acquire the UI regarding the device connected to the network through the network and interact with the device, so that the user can easily manipulate the device at a remote distance and can easily grasp the statue of the device.
