摘要： In an electromagnetic switch, a magnetic plate, which forms a part of a magnetic circuit, and a bobbin of a second coil are assembled as one body by insert molding. An outer circumferential surface of the magnetic plate is adhered to an inner circumferential surface of a cylindrical frame made of metal. Because a large amount of heat energy generated in the second coil is transmitted to the magnetic plate, this can discharge the heat energy through the magnetic plate to the cylindrical flame. Because a mounting surface of the cylindrical frame is fixed to an end part of a starter housing case, it is possible to easily discharge the heat energy generated in the second coil through the cylindrical frame to the starter housing case. This structure prevents a temperature rise of the second coil and contributes entire-size reduction of the electromagnetic switch.

摘要： In a system, a starter includes a motor for rotatably driving an output shaft with a pinion and an actuator that shifts the pinion toward a ring gear to be engaged with the ring gear. A monitor unit monitors a rotational speed of the internal combustion engine. The rotational speed of the internal combustion engine drops after an automatic control for stop of the engine. When an engine restart request occurs with the rotational speed being within a preset range during the rotational speed of the internal combustion engine dropping by the automatic control for stop of the engine, a drive unit drives the actuator to shift the pinion toward the ring gear to be engaged with the ring gear. The drive unit rotatably drives the motor with the pinion being engaged with the ring gear to thereby crank the crankshaft.

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.

A plurality of concavo-convex parts is provided on a surface of the fixed contact that faces the movable contact. A plurality of concavo-convex portions is provided on another surface of the fixed contact that faces an anti movable-contact side. The concavo-convex portions are arranged so that positions of concave parts of the concavo-convex portions match positions of convex parts of the concavo-convex portions provided in the opposite surface of the fixed contact. The concavo-convex parts are at least partly curved, and have the same height and project in a height direction from the fixed contact.

摘要： In a system, an angle sensor outputs a pulse each time an output shaft of an internal combustion engine rotates by a preset angle, and a calculator calculates speed-change information indicative of a change in a speed of rotation of the output shaft based on the pulses outputted from the angle sensor. A determiner determines, based on the speed-change information, whether at least one of the pulses outputted from the angle sensor represents a proper timing for a preset of a pinion of a starter with a ring gear mounted on the output shaft. A pinion engaging unit shifts the pinion toward the ring gear so that the pinion is engaged with the ring gear when it is determined that the at least one of the pulses outputted from the angle sensor represents the proper timing for the preset of the pinion with the ring gear.
