PURPOSE:To eliminate a motor-driven blower for an exclusive use of a reverse-current preventive diode by mounting a support attached with the diode at a cover of predetermined shape and attaching the cover to the cooling air intake side of a motor generator. CONSTITUTION:Silicon diodes SR1-SR4, voltage dividing resistors R1-R4 connected in parallel with these diodes, surge absorption capacitors C1-C4 and a support 25 for supporting the cooling fins 21 of the diodes SR1-SR4 are mounted in the cover 22 to form a reverse current diode for a motor generator. A ventilating hole 23 is formed at the head 22b of the cover 22, and a collar 22a is provided at the peripheral edge thereof, and mounted at the intake port of the cooling air for the generator having a self-cooling blower. Thus, it can eliminate the motor generator for an exclusive use at the reverse current preventive diode. |
