MOTOR

摘要

PURPOSE: A motor is provided to improve the efficiency of the motor by providing the thrust directional load through a sliding support means to a hob rotated about a shaft. CONSTITUTION: A lower end portion of a shaft(200) is fixed to the upper surface of the center of a housing(100). A stator(300) which comprises a core and a coil is fixed to the outer peripheral surface of the lower portion of the shaft(200). A hob is slidably supported though a plurality of bearing surfaces in the radial direction. A rotor(500) which comprises a yoke(510) and a magnet(520) is installed on the inner peripheral surface of the lower portion of the hob. A sliding support means supports the hob(400) to be rotatable in the thrust direction.
