20120181894 | ROTOR FOR ROTARY ELECTRIC MACHINE - A rotor for a rotary electric machine, the rotor being arranged to face a stator and being roratably attached to a housing, the rotor includes a core body formed by a plurality of core sheets laminated in a direction of a rotational axis of the rotor, first and second end plates arranged at both end surfaces of the core body in a direction where the core sheets are laminated, and a fixing member fixing the first and second end plates to the core body to hold the core body by the first and second end plates, wherein at least one of the first and second end plates is formed by a plurality of composition members overlapping in a thickness direction of the first end plate and the second end plate. | 07-19-2012 |
20120299436 | STATOR FOR ROTATING ELECTRICAL DEVICE AND STATOR RETAINING RING - A stator for a rotating electrical device includes a stator retaining ring for the stator in a cylinder form that retains a plurality of cores. The stator retaining ring includes the cylinder portion where the cores are attached, and a plurality of fixing flanges where the stator retaining ring retains the housing with screws. A pair of through-holes representing a group of through-holes arranged near to one another extends through each of the fixing flanges. A separation distance β in the circumferential direction defined between the pair of the through-holes belonging to the same group of the through-holes is smaller relative to a separation distance γ in the circumferential direction defined between adjacent through-holes belonging to different groups of the through-holes. | 11-29-2012 |
20130076197 | ROTOR FOR ELECTRIC ROTATING MACHINE AND METHOD FOR MANUFACTURING THE SAME - A rotor for an electric rotating machine includes a core body member formed, first and second end plates provided at respective side faces of the core body member, and a fixing member inserted into through holes provided at the core body member and the end plates. The end plates include positioning portions at an outer or inner circumferential surface, wherein when the fixing member is engaged with the end plates, the positioning portion is engageable with positioning receive portions corresponding to the positioning portions and positioning at radially outer or inner portion of the end plate. When one of the end plates is placed facing the side face of the core body member in a reversed state, the end plate and the core body member are not assembled each other by positional relationship between the positioning portions, the positioning receive portions and the through holes. | 03-28-2013 |
20130076198 | ROTOR FOR ELECTRIC ROTATING MACHINE AND METHOD FOR MANUFACTURING THE SAME - A rotor for an electric rotating machine includes a core body member formed with laminated core plates and a pair of end plates sandwiching opposing ends of the core body member. An output member is connected to an inner peripheral portion of one of the end plates with a connecting member. A first through-hole for allowing an insertion of the connecting member is press formed from the direction opposite to the direction outer and inner peripheral portions of the one of the end plates are press formed. Shear-droops formed at the outer and the inner peripheral portions of the one of the end plates during the press forming are arranged on the surface opposite to the surface thrusting the core body member. A shear-droop formed at the first through-hole during the press forming is arranged on the surface of the one of the end plates thrusting the core body member. | 03-28-2013 |
20130140939 | ROTOR OF ELECTRIC MOTOR AND MANUFACTURING METHOD THEREOF - A rotor of an electric motor comprises a rotor core composed of laminated steel plates and having pin holes; a pair of end plates having insertion holes of a diameter being greater than or equal to the diameter of the pin holes of the rotor core and arranged on opposite sides of the rotor core; and fastening members inserted into the pin holes of the rotor core, fitted in the insertion holes of the pair of end plates, and pressed by staking at opposite end portions thereof, wherein each fastening member has a body portion, main radially-expanded portions continued from the body portion and being larger in diameter than the insertion holes of the end plates, and protrusions continued from the main radially-expanded portions and protruding from the main radially-expanded portions. | 06-06-2013 |
20130154427 | STATOR OF ROTARY ELECTRICAL MACHINE - A stator of a rotary electrical machine, includes a core unit configured by a plurality of core assemblies each including a laminated steel plate, an insulator, and a coil; a bus ring facing the core unit; and an accommodating box arranged at the insulator, accommodating an end portion of the coil, and including radially inward and outward engaged portions, the insulator including radially inward and outward extending portions, the radially inward extending portion including a radially inward engagement portion about which the accommodating box rotates in a radial direction of the core unit from an initial attachment position to an attached position and which engages with the radially inward engaged portion, the radially outward extending portion including a radially outward engagement portion which engages with the radially outward engaged portion in accordance with the rotation of the accommodating box to move the accommodating box in the radial direction. | 06-20-2013 |
