摘要： The present invention provides an engine unit, or the like, having a high-load region and a low-load region, and capable of lessening a variation in the position where rotation of a crankshaft stops after combustion of a four-stroke engine body is stopped. The engine unit includes: a four-stroke engine body having a high-load region and a low-load region; a three-phase brushless motor that starts the four-stroke engine body and generates power after starting the four-stroke engine body; an inverter including a plurality of switching parts; and a control device. The control device is configured to, while the crankshaft is in forward rotation after a combustion operation of the four-stroke engine body is stopped, control the plurality of switching parts so as to short-circuit terminals of a plurality of windings such that a resistance is applied to the forward rotation of the crankshaft, forcing the crankshaft to stop forwardly rotating in a compression stroke of the four-stroke engine body.

摘要： A motor rotation angle detection device, comprising a resolver (56) which detects a rotation angle of a motor (M) generating an assist torque for steering road wheels. The resolver (56) includes an annular rotor (60) disposed inside an annular stator (59) with an air gap interposed in between an outer circumferential surface of the rotor (60) and an inner circumferential surface of the stator (59), so that the stator (59) and the rotor (60) are rotatable relative to each other, wherein a rotor supporting member (53) is connected to a rotary shaft (47) of the motor (M), and the rotor (60) extends out from an axial end portion of the rotor supporting member (53) so as to surround an outer periphery of the rotary shaft (47). With such a motor rotation angle detection device, it is possible to stabilize the magnetic permeability of the rotor (60), and accordingly to increase an accuracy with which the rotation angle of the motor (M) is detected.
