摘要： A starter to start an engine mounted on a vehicle provides an electromagnetic solenoid to push a pinion gear towards a ring gear side, an electromagnetic switch to open and close a motor contact point. The electromagnetic solenoid and the electromagnetic switch are individually controlled by an Electronic Control Unit i.e., ECU. When an idle-stop is triggered, the ECU controls a starter relay to be closed during the ring gear is rotating whereby the pinion gear together with a clutch are pushed out to counter-motor direction by the electromagnetic solenoid. As a result, the pinion gear meshes with the ring gear that is rotating at lower rotational speed. Therefore, the inertial mass of the starter is added to the ring gear so that swinging of the engine can be suppressed.

摘要： A starter includes an electromagnetic solenoid that generates force for pushing a pinion gear 6 to a ring gear side, and an electromagnetic switch that opens and closes a motor contact point. When idle-stop is performed, an ECU energizes a solenoid coil of the electromagnetic solenoid during inertial rotation until the ring gear stops rotating. After rotation of an engine is stopped, the ECU stops energizing the solenoid coil. As a result, in the starter, the pinion gear can mesh with the ring gear that is rotating by inertia without use of the rotational force of a motor. The meshed state can be maintained even after energization of the solenoid coil is stopped.

摘要： An armature composed of a shaft and an armature core is rotatably supported in a housing of a rotary electric machine. The shaft is forcibly inserted into a center hole of the armature core formed by laminating core sheets. Each core sheet has a center hole and outer holes connected to the center hole. A contour of the center hole is not continuous because the outer holes are connected thereto. The shaft can be firmly connected to the laminated core sheets with a relatively low inserting force. The shaft has a smooth outer surface having no knurls or the like. In addition, the outer holes of the laminated core sheets form cooling air passages in the armature core in its axial direction.

摘要： A front end of a starter motor housing is sealed by a resilient seal member disposed between a bearing and a front end wall of the housing. A shaft carrying a pinion at its front end is rotatably and slidably supported by the bearing in an over hang fashion. The seal member is a cup-shaped ring having a circular outer wall, a bottom wall and a center hole. A sealing lip slidably contacting the rotating shaft is formed around the center hole. The circular outer wall of the seal member is tightly and hermetically held between an outer ring of the bearing and front end wall of the housing, so that the seal member is not displaced in the axial direction. The bottom wall is S-shaped forming a depressed portion facing the bearing to provide more space for retaining lubricant therein.

摘要： An engine start system which may be employed in automotive idle stop systems. To start an engine, the system brings a pinion gear into engagement with a ring gear coupled to the engine and turns on an electric motor to rotate the ring gear through the pinion gear to crank the engine. When it is requested to start the engine during deceleration of the engine before stop thereof, the system thrusts the pinion into engagement with the ring gear and then turns on the motor to rotate the pinion gear, in other words, delays the activation of the motor until after the pinion gear has engaged the ring gear. This minimizes mechanical impact or noise arising from the engagement of the pinion gear with the ring gear and improves the reliability in engagement with the ring gear during the deceleration of the engine and durability of the system.

摘要： A starter includes a motor, an output shaft, a pinion gear, a lever, a lever actuator, a supporting frame, and a fulcrum supporter. The motor includes a rotation shaft to which the output shaft is linked. The pinion gear is provided on the output shaft and configured to mesh with a ring gear of an engine to start the engine. The lever has a first end, a second end that is linked the pinion gear, and a fulcrum portion. The lever actuator works to move the first end of the lever to pivot the second end on the fulcrum portion. The supporting frame rotatably supports the output shaft. The fulcrum supporter, which is integrally formed with the supporting frame, works to support the fulcrum portion of the lever to achieve pivotal movement of the second end to bring the pinion gear into mesh with the ring gear of the engine.
