1. A power control system for an a-c motor having input a-c terminals;
- said power control system comprising a plurality of inverter circuits each in a separate inverter module and each inverter module having respective a-c and d-c terminals; and
a control circuit for said inverter circuits;
a heat sink fixed to said motor at one side thereof;
said inverter modules being mounted on another side of said heat sink opposite to said one side whereby said heat sink is disposed between said inverter modules and said motor, and each inverter module having it'"'"'s a-c terminal connected to a respective input a-c terminal of said a-c motor by a respective short power conductor that extends through said heatsink;
said control circuit including a microcontroller for controlling said inverter circuits being mounted remotely from said inverter modules and coupled thereto by a low power interface link, and each said inverter circuit including a plurality of switching devices.

Abstract
The power switches of an inverter are mechanically integrated with an electric motor of a vehicle and are mounted on the end plate of the motor and employ short connections between the motor a-c terminals and the inverter a-c output terminals. Bond wireless modules are employed. The electronic controls for the inverter are mounted on a main control board which is positioned remotely from the inverter and is not subject to the heat and EMI produced by the inverter.
