ABSTRACT:
A power train assembly for delivering electrical power to a driven device such as a motor is constructed of an IMS board and a PCB. A considerably smaller and standardized IMS board is obtained by limiting the components on the IMS board to include only inverter transistors, input rectifiers and a thermistor. The only other component is a connector for effecting a simple vertical connection to the overhead printed circuit board which contains the device control and drive components. The power train assembly realizes surface board savings on the order of between 40% to 50% in the IMS. The height of the IMS is also reduced, which makes it possible to replace the usual potting compound with a thin surface coating.
