Abstract: An electric motor includes: a rotary shaft member rotating about an axis; a rotor including a rotor core, which has an annular shape and is provided on the rotary shaft member, and a magnet provided on the rotor core; a stator including a stator core, which has an annular shape and is disposed at an interval from the rotor core in a radial direction that is a direction orthogonal to an axial direction of the rotary shaft member, and a stator coil wound around the stator core; a field yoke, which has an annular shape, includes the rotor and the staorm, and has a fixed relative positional relationship with the stator core; and a case member, which has a side wall extending in the axial direction to face an outer peripheral surface of the field yoke, the field yoke being fixed to the case member.

Abstract: A rotary electric machine includes: a shaft that rotates about an axial direction; a rotor that is disposed around the shaft and that includes a rotor core and a plurality of magnets provided in the rotor core; a stator that is disposed around the rotor and that includes a stator core and a stator coil provided in the stator core; a magnetic flux short circuit plate that is disposed so as to face the rotor core in the axial direction and that moves in the axial direction; a biasing member that biases the magnetic flux short circuit plate to a side away from the rotor core; a holding member that holds the biasing member; and a fixing member that fixes the holding member to the shaft. Further, a strength of a material of the fixing member is higher than a strength of a material of the holding member.

Abstract: To provide a controller that can slow down progression of deterioration of an internal combustion engine caused by repeated occurrence of LSPI. An index value of the degree of deterioration of the internal combustion engine caused by LSPI is calculated. If the index value exceeds a first threshold, when the temperature of cooling water that cools a part of the peripheral wall of a cylinder that is close to a combustion chamber is lower than a threshold temperature, and the internal combustion engine is running in a determined operational region set in a low speed and high load region, the proportion of fuel injection by an in-cylinder injection valve is reduced to increase the proportion of fuel injection by a port injection valve compared with before the index value exceeds the first threshold, thereby suppressing occurrence of LSPI.

Abstract: A control device for an internal combustion engine includes a knock control system, a cooling system, and an electronic control unit. The knock control system is configured to ignite a spark plug an ignition crank angle obtained by retarding the ignition crank angle in response to an occurrence of the knocking. The electronic control unit is configured to supply a command value corresponding to a target value of a cooling parameter to the cooling system such that the cooling system performs cooling of the internal combustion engine according to the command value. The electronic control unit is configured to correct the command value based on a KCS learned value such that as the KCS learned value increases, a correction amount for correcting the command value increases in correction amount in a direction in which a cooling capacity of the cooling system increases.
