MACHINE ELECTRIQUE ROTATIVE POUR VEHICULE

摘要

In a vehicle electric rotating machine having a power section formed of a pair of inverter modules of switching elements and diodes connected in parallel thereto, and a control circuit section that controls mentioned power section, there are separately located the control circuit section on the upstream side, and the power section on the downstream side; as well as a through hole is formed in mentioned control circuit section so that mentioned cooling air flows linearly through mentioned power section.
