Title: Engine starter
Inventor: OSADA MASAHIKO
IPC: H02P1/18
Filed: 2001-10-16
Abstract: PROBLEM TO BE SOLVED: To simplify a control system by integrating the current control of an excitation coil 4 with the control of the main current of a starter motor 3. SOLUTION: A current control means of a starter comprises a control element 9 disposed between a battery 8, a motor contact 6 and the excitation coil 4, and a starting ECU 10 to drive the control element 9. The control element 9 has the element capacity to permit the main current of the starter motor 3. The starting ECU 10 changes the control specification to the control element 9 before and after the motor contact 6 is closed. This means that, before the motor contact 6 is closed, the control start timing of the coil current is determined by the battery voltage, and then, the coil current is limited to the predetermined value so that the moving speed of a plunger 5 is slow. After the motor contact 6 is closed, the rise of the main current is controlled to be slower.
