WIPO Patent Application WO/2017/221994
Kind Code:
A1
Abstract:
The present invention provides a coreless motor in which a unit is coupled to the end of a rotating shaft within the coreless motor and the unit is incorporated without increasing the length in the direction in which the rotating shaft of the coreless motor extends. The coreless motor is provided with: a cylindrical coil that is arranged concentrically with a central shaft serving as the center of rotation, that extends in the direction in which the central shaft extends, and in which the end surface on one side of said cylindrical coil is supported by a stator; a cylindrical inner yoke and a cylindrical outer yoke that have the coil sandwiched therebetween in the radial direction and that form a magnetic circuit therebetween; a rotor that is arranged concentrically with the central shaft and that is supported on the central side thereof in the radial direction by the central shaft; and a housing that is cylindrical, said housing being either a housing that is provided with a cylindrical section arranged on the exterior of the outer yoke in the radial direction and that is capable of rotating with respect to the central shaft or a housing that is provided with a cylindrical section arranged on the exterior of the outer yoke in the radial direction and in which the cylindrical section is made to rotate by rotation of the central shaft. A unit coupled to the end of the rotating shaft within the coreless motor is provided to a space within the coreless motor.
