The motor includes: a stator with a coil wound therearound; and a control board coupled to one side of the stator, the coil being electrically connected to the control board, wherein the control board includes a coupling recess in which the coil is fixedly bonded and a guide recess allowing the coil to be moved into the coupling recess from the outside of the control board.

Abstract: Disclosed herein is an electric blower including: an impeller; a driving module including a rotor part coupled to the impeller in order to driving the impeller and a stator part, the rotator part including a magnet and the stator part including an armature formed of a core positioned so as to face the magnet and a coil; a motor housing having the driving module mounted thereon; and a control module mounted on the motor housing and controlling the driving module.

Abstract: Disclosed herein are a controller embedded switched reluctance motor assembly and a method of assembling thereof. Particularly, according to the present invention, a controller controlling the motor unit is installed in a housing, such that a separate process of installing the controller may be omitted, thereby facilitating assembling of the switched reluctance motor assembly. In addition, since a separate installation space of the controller is not required, a vacuum cleaner including the switched reluctance motor assembly may be miniaturized, and since the controller is installed in a state in which a motor unit and an insulator are coupled to each other and then installed in the housing, intermediate tests of the controller or the motor to unit may be easily performed, such that defects may be reduced. Further, the controller is in the housing, such that the controller may be protected from external disturbance.

Abstract: Disclosed herein is a switched reluctance motor assembly including: a shaft forming the center of rotation of a motor; a rotor part rotatably coupled to the shaft; a balancing member including the rotor part and formed so as to enclose the shaft; a sensor magnet coupled to a lower end portion of the balancing member in an axial direction; and a printed circuit board having a hall sensor attached thereto so as to face the sensor magnet at a lower portion of the sensor magnet in the axial direction. According to the present invention, the coupling precision of the sensor magnet for sensing the position of the rotor part forming the rotor of the switched reluctance motor assembly may be improved.

Abstract: Disclosed herein is a switched reluctance motor assembly capable of reducing an assembling error that is generated according to separate assembling and improving precision of assembling of bearing parts by forming a diffuser part and a motor housing integrally with each other. In the switched reluctance motor assembly, the diffuser is coupled integrally with the housing, such that a separate member for fixing the diffuser is omitted, thereby making it possible to reduce vibration according to driving of a motor and noise according to the vibration.

Abstract: Disclosed herein is a motor housing including: a housing body accommodating a stator and a rotor therein; and a supporting frame coupled to the housing body and supporting a shaft of the rotor, wherein an end portion of the housing body is provided with a fixing part that is extended inwardly, such that the supporting frame is coupled to the fixing part.

Abstract: An automatic hinge module and apparatus for opening and closing a toilet bowl. The module includes: a motor, which generates a driving force; a housing, of which one end is coupled to a body of the motor; a drive shaft, which is rotatably coupled to the housing, and which has one end coupled to an output shaft of the motor, such that the centers of rotation of the drive shaft and the output shaft coincide, to allow the drive shaft to transfer the driving force to the exterior; and a spring, one end of which is coupled to the housing, and the other end of which is coupled to the drive shaft, such that the spring provides an elastic force to the drive shaft in a direction of rotation of the drive shaft. Using this module, the cover and seat of a toilet can be opened and closed automatically.
