摘要： A control device for a switched reluctance motor includes an inverter having a switching circuit that switches a magnetic pole to provide a first winding pattern or a second winding pattern. With respect to a boundary dividing a driving range of the switched reluctance motor into two ranges, the control device performs switching to the first winding pattern when the torque and the rotational speed are located in the first range on the low load side, performs switching to the second winding pattern when the torque and the rotational speed are located in the second range, allows switching of the magnetic pole in a case where a current of the phase whose magnetic pole is to be switched among the three-phase coils is 0, and prohibits switching of the magnetic pole in a case where the current of the phase whose magnetic pole is to be switched is not 0.

摘要： This rotor for a rotating electric motor includes a hollow cylindrical rotor core with a plurality of laminated electromagnetic steel plates. The inner and outer circumferential surfaces of the rotor core each face a magnetic gap. The rotor core is interposed between a first rotating support member and a second rotating support member. A flange is formed on a first end of a tubular pin protruding from a first hole of the first rotating support member. A tubular expansion part of the tubular pin plastically deforms due to fluid pressure so as to come into close contact with a through hole of the rotor core, the first hole of the first rotating support member, and a second hole of the second rotating support member.

摘要： A heat exchanger includes a plurality of plates that is stacked together to constitute first flow passages, second flow passage, third flow passage, fourth flow passage and fifth flow passage. An engine coolant flows through the first flow passages. An engine oil flows through the second flow passages and fourth flow passages. A transmission oil flows through the third flow passages and fifth flow passages. Triple-flow-passage arrangement layers in each of which each first, second, and third flow passages are disposed, and dual-flow-passage arrangement layers in each of which each fourth and fifth flow passages are disposed are alternately arranged such that flow passages of each same type are not overlaid with one another in a stacking direction of the plates.
