Power train partition for 10 horsepower motor controller
First Claim
1. A power train assembly for delivering electrical power to a driven device, the assembly comprising:
- an IMS (insulated metal substrate) board for carrying and electrically interconnecting power components and a PCB (printed circuit board) for holding control and drive components;
the IMS board having mounted thereon exclusively power transistors for forming a power inverter circuit, input rectifier diodes, a thermistor and a connector for providing connectivity to the PCB, thereby realizing a standardized IMS board of comparatively smaller substrate area;
the PCB comprising said control and drive components which components include drive elements, a current sense, a connector to the IMS board, and terminals for effecting electrical connections to the driven device; and
the PCB being mountable directly above the IMS board, and the respective connectors of the IMS board and the PCB mating with one another vertically.

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.
