Abstract: A stator for a rotary electric machine with wedge members insertable into slots without being bent or folded is provided. A coupling portion is integrally formed at a non-inserted end portion, which is not inserted into a slot, of a wedge member, the coupling portion extending across an end of a partition wall portion and an end of a block portion. The wedge member and the coupling portion are formed of a synthetic resin material. Two or more coupling portions of two or more adjacently disposed wedge members are integrally formed as a continuous coupling portion.

Abstract: An airtight-type electric motor capable of reducing vibration is provided. Inside ribs of a pair of end brackets and are respectively fitted into core end portions of a stator core. Outside ribs of the pair of end brackets and are respectively brought into contact against end surfaces of the core end portions of a yoke of the stator core. With this arrangement, the pair of end brackets and are fixed to the stator core, and a housing and the stator core are arranged, without being coupled together.

Abstract: A leading end portion of a lead wire holder located in a direction opposite to a direction in which six lead wires extend is inserted toward concave surfaces through an insertion opening. After the leading end portion has entered toward the concave surfaces and gotten out therefrom, the leading end portion is situated between opposed surfaces of hooks and a holder receiving portion bottom surface. With this arrangement, a back surface of a rear end portion located opposite to the leading end portion of the lead wire holder comes into contact with end surface portions of partitioning wall portions. An end surface portion of the rear end portion faces projecting portions. Then, the six lead wires are partially received in six lead wire receiving portions, respectively.

Abstract: Depressed portions for being fitted with two rotor collars 51, 52 are formed in two rotor stacks 72, 71 opposed to each other in an axial direction of the rotating shaft 1 with the rotor collars 51, 52 therebetween. Each of the rotor collars 51, 52 includes a central portion 5a and a pair of fitting portions 5b. Shapes of the depressed portions 8A and fitting portions 5b are both defined so that there occurs no relative displacement in the radial direction of the rotating shaft 1 between the rotor stacks 72, 71 and the rotor collars 51, 52 with the fitting portions 5b fitted into the depressed portions 8A. With this arrangement, position alignment of rotor collar and rotating shaft can easily be performed.

Abstract: The present invention provides a rotary electric machine, of which the occupied volume can be reduced and which allows a space in an electric apparatus equipped therewith to be utilized effectively. A slot insulator 15 is integrally formed with a holder mounting portion 25, a whole or major part of which is positioned on one of end faces of a yoke 11 of a stator core 7. A lead wire holder 27 includes a connection holding portion 27a for disposing a plurality of connections 30, in which lead-out wires of windings are connected with corresponding core wires 29a of lead wires 29, at a predetermined interval so that the connections do not contact with each other. The lead wire holder 27 is arranged so that the connection holding portion 27a is positioned over a part of the windings 9 and the holder mounting portion 25 when the lead wire holder is attached to the holder mounting portion 25.

Abstract: The present invention provides a rotor for a hybrid type stepping motor in which position alignment of rotor collar and rotating shaft can be easily performed and relative displacement in a radial direction of the rotating shaft can be prevented from occurring between rotor stacks and a rotor collar. Depressed portions for being fitted with a rotor collar 8A are formed in two rotor stacks 7B, 7A opposed to each other in an axial direction of the rotating shaft 1 with the rotor collars 5A, 5B therebetween. Each of the rotor collars 5A, 5B includes a central portion 5a extending in the radial direction of the rotating shaft 1 and a pair of fitting portions 5b which are disposed at both sides of the central portion 5a in the axial direction of the rotating shaft 1 and are fitted into the depressed portions 8A.
