Abstract
A controller for driving an electric motor includes a rectifying circuit for converting AC power from a source to DC power, an inverting circuit coupled to the rectifying circuit via a DC bus for converting the DC power to controlled AC power in response to control signals and control circuitry for generating control signals for driving the inverting circuit in accordance with a preset control routine. The rectifying and inverting circuits are included in a power substrate module, while the control circuitry is included on a control circuit board separate from the power substrate module. The control circuit board is coupled to the power substrate module via a plurality of conducting pins and the controller circuitry is housed in an enclosure. A plurality of terminal conductors are supported on the control circuit board for transmitting power to and from the power substrate module via the conducting pins through the control circuit board. The terminal conductors terminate outside the enclosure for ready access and connection to phase conductors from the source and to the motor.
