WIPO Patent Application WO/2017/056768
Kind Code:
A1
Abstract:
Provided is a motor that includes: a stationary part having a shaft which extends vertically along a central axis; a rotating part that rotates about the central axis; and a bearing that supports the rotating part so as to be rotatable with respect to the shaft. The rotating part includes, on the radial outer side from the stationary part, the following: a cylindrical motor casing that extends in the axial direction with the shaft as the center of such extension; and a magnet disposed on the inner circumferential surface of the motor casing. The stationary part includes: a base plate disposed so as to be perpendicular to the shaft; and a stator positioned on the axial-direction lower side of the base plate or the axial-direction upper side of the bearing. The stator includes: a stator core having an annular core back having as the center thereof the central axis and a plurality of teeth that extend from the core back towards the radial-direction outer side thereof; and a coil having conductor wires which are wound onto the teeth. A first conductor wire which is led out from the coil is connected to the base plate, and a second conductor wire is connected to the axial-direction upper surface of the base plate.
