A slip ring device includes a pair of slip rings, a pair of connecting conductors, and an insulating molded body in which the slip rings and the connecting conductors are provided. The insulating molded body includes a molded body main body portion disposed in a position further from a rotor main body than a bearing provided on a shaft, the slip rings being provided in the molded body main body portion, an opposing portion disposed between the bearing and the rotor main body, and a pair of beam portions that connect the molded body main body portion to the opposing portion, the connecting conductors being provided respectively in the beam portions. A pair of shaft grooves respectively accommodating the pair of beam portions are provided in the shaft. A spreading suppression portion for preventing resin with which a field coil is impregnated from spreading into the shaft grooves is provided in the opposing portion.

An axial flux rotating electrical machine is disclosed, the machine comprising a stator (10), a cooling jacket (22, 100) inside the stator for cooling the stator, and stator windings (24) around the stator and the cooling jacket. The cooling jacket comprises a plurality of independent protrusions (76) which extend radially outwards through the stator windings and which secure the stator to the machine. This can allow the stator to be secured without the need for direct contact with the stator.

The electric motor includes a rotor and a stator, the stator having a conductive wire wound thereon via a stator core and insulators. The insulators include an annular outer peripheral wall portion with the conductive wire run on an outer periphery side of the peripheral wall portion, a plurality of winding body portions protruding radially from the outer peripheral wall portion, and an inner flange portion. The outer peripheral wall portion on the winding body portion side includes an outer peripheral surface formed in an arc shape. The radial thickness of the outer peripheral wall portion is increasingly greater toward the circumferential center of the winding body portions.

Provided are a stator for an aspiration motor, an aspiration motor and an in-car sensor using the same, in which a bobbin is integrally formed with a stator, to thus use an inexpensive insulation wire and enhance a productivity and lower an inferiority using an insert-molding technology. The stator for the aspiration motor includes a stator support plate, a support boss which is vertically extended from the central portion of the stator support plate, a bobbin which is bent and formed on the lateral surface of the support boss, and which is separated from the upper side surface of the stator support plate, to thereby provide a space, and a stator coil which is formed by making a wire wound in the space provided by the bobbin.

A power tool has a motor having a stator made by separately forming pole pieces, return path pieces and field coils. The field coils are placed over necks of the pole path pieces and the return path pieces are affixed to the pole pieces. An armature having an outside diameter of at least 0.625 the outside diameter of the stator is placed in the stator. The field coils may be formed so that they extend beyond pole tips of the pole pieces.
