In a wobble removal shaft coupling device including a wobble removal gear having an internal gear with a first central axial line and an external gear meshing with the wobble removal gear and having a second central axial line. The first and second central axial lines are in parallel with and offset from each other, and the external gear teeth are identical in number to the internal gear teeth of the wobble removal gear. At least one of the two sets of the gear teeth are resiliently deformable in a circumferential and/or radial direction so as to allow the two gears to be meshing with each other while permitting an eccentric wobbling movement of the external gear relative to the internal gear without requiring a play or a sliding engagement. The wobble removal shaft coupling device can be incorporated in a hypocycloid reduction gear device.

Wobble removal shaft coupling and hypocycloid reduction gear device using same

A stator includes: a plurality of divided cores disposed to have a ring shape; a stator winding toroidally wound on the stator; and a holding member that holds the divided cores in the ring shape. Each of the divided cores includes: a bobbin part for the stator winding; a yoke extending from the bobbin part in the circumferential direction; a connection part extending from the yoke outwardly in a radial direction with a connection face that is connected to the holding member; and a tooth extending from the yoke inwardly. The connection part has a magnetic gap to increase a magnetic resistance in a path of magnetic flux, generated by the stator winding, leaked to the holding member through the connection face. The magnetic gap is a notch or a weld.

Stator for electrical rotating machine

An armature coil for a rotary electric machinery includes a plurality of identical coil blocks each formed by a plurality of turns of and elongated conductor. Each of the coil blocks includes two groups of axial sections which are diametrically opposed to each other, and curved sections joining the two groups to each other at each axial end. The axial sections of one of the groups is disposed in an inner cylindrical layer while the axial sections of the other of the groups are disposed in an outer cylindrical layer which is coaxial with the inner cylindrical layer. The coil blocks are combined with each other by circumferentially shifting one coil block from another in such a maimer that the axial sections are arranged circumferentially along the inner and outer cylindrical layers, one next to another.
