Abstract:
An engine starter comprising:an electromagnetic switch including: a motor contact point; a plunger; and an exciting coil, wherein the motor contact point is closed by activating the plunger using electromagnetic force generated by the exciting coil; a starter motor energized by closing the motor contact point, for generating rotational force; a contact-point detecting device for detecting a closed state of the motor contact point; a control device provided among a battery, the motor contact point and the exciting coil; a current control unit, wherein the current control unit controls current flowing into the exciting coil and current flowing into the starter motor using the control device, and wherein the current control unit changes a control specification for the control device before and after closing of the motor contact point; and a pinion, wherein the pinion is pushed out while interlocked with movement of the plunger and is engaged with a ring gear of an engine, to start the engine by transmitting a rotational force of the starter motor from the pinion to the ring gear.
