摘要： An electrically operated vehicle driving controller has an electrically operated machine driving section for operating an electrically operated machine; a driving section temperature detecting section for detecting the driving section temperature of the electrically operated machine driving section; a limit ratio calculating processor for calculating a limit ratio for limiting the torque of the electrically operated machine on the basis of the driving section temperature; a rotating speed calculating processor for calculating the rotating speed of the electrically operated machine; and a limit torque calculating processor for calculating an electrically operated machine limit torque corresponding to an electrically operated machine maximum torque set corresponding to the rotating speed on the basis of the limit ratio. Because the torque of the electrically operated machine is limited in a limit ratio corresponding to the temperature of the electrically operated machine, it is possible to prevent the characteristics of the electrically operated machine from being reduced.

摘要： A stator includes a stator core, a stator winding, and insulation paper sheets. The stator winding is constructed by forming a Y connection of phase windings each of which is constructed by inserting conductor segments into slots from a lower end side of the stator core and joining distal end portions of the conductor segments which protrude from an upper end side of the stator core. One of the insulation paper sheets is disposed between radially adjacent ones of joint portions that constitute a group of joint portions in a U-phase winding that are the nearest to a U-phase terminal. In the same manner, the other insulation paper sheets are disposed with respect to a V-phase winding and a W-phase winding. Surfaces of the other joint portions are covered with an insulation resin. Insulation paper sheets are disposed between joint portions that need long creepage distances and the insulation resin is used to cover surfaces of the other joint portions that do not need a long creepage distance.

摘要： An object is to provide a rotor manufacturing method capable of reducing a rotor unbalance amount by controlling a magnet arrangement position in a rotor core and improving work efficiency when fixing a magnet to the rotor core by using resin. A lower surface of a rotor core is arranged in a lower mold. A magnet is arranged in a lower mold. A magnet is contained in each of magnet containing holes formed in the rotor core in such a manner that a predetermined space is assumed between an upper surface of the rotor core and an upper surface of the magnet. An upper mold is arranged on the upper surface of the rotor core. The upper mold and the lower mold apply a pressure to the rotor core and a molten resin is supplied with pressure from an internal diameter side via the predetermined space into the plurality of magnet containing holes from respective cylinder arranged in the upper mold. Thus, the magnets are molded by resin while pressing the magnets toward the outer diameter side of the magnet containing holes.
