20100219816 | RESOLVER - A resolver is provided with a rotor plate fitted to a key groove in a rotating shaft and connected to the rotating shaft, and also with a resolver stator for detecting the rotational position of the rotor plate. The resolver stator is provided with a resolver cover for protecting a coil board of a stator core and fixed to the stator core. The coil board is provided with holes fitted to stator pins which are projections of the stator core, coil patterns each formed so as to center on each of the holes, and lead wires connected to the coil patterns formed on the coil board. The outer peripheral portion of the stator core is provided with long mounting holes for fixing the resolver to the housing of a rotating machine, such as an electric motor or a generator, and also with engaging holes engaging with claws of the resolver cover. | 09-02-2010 |
20110048092 | APPARATUS FOR PRODUCING MOTOR COIL - An apparatus for producing a motor coil is to produce a coil to be used for a stator of a motor by automatically winding a flat rectangular conductive wire by use of a winding machine. This apparatus comprises: an uncoiler for feeding the conductive wire wound and accumulated on a bobbin to the winding machine; an inertia measuring device for measuring inertia of the uncoiler when feeding the conductive wire; chucks and for measuring a resistance value of the conductive wire; and an operating console for setting the winding condition of the rectangular wire to be wound by the winding machine based on the measured inertia and the measured resistance value. The operating console controls the winding machine based on the set winding condition to wind the conductive wire. | 03-03-2011 |
20120017425 | STATOR AND METHOD FOR MANUFACTURING THE SAME - A stator core is fixed by a centering jig, and in this state, a fixing hole is formed in a flange portion provided on a fastening ring for the stator core, using a central position as a reference for positioning, by drilling with a drill. The fixing hole is opened to be located at a distance relative to the central position. In a plan view, the fixing hole is opened at a predetermined central angle interval (for example, intervals of 120°) relative to the central position. | 01-26-2012 |
