1. A controller for regulating the output characteristics of an electric motor comprising:

  • a power substrate module including a rectifying circuit for converting alternating current power from a source of electrical power to direct current power and an inverting circuit coupled to the rectifying circuit via a direct current bus, the inverting circuit converting the direct current power to controlled alternating current power to drive the electric motor in response to control signals;

    a control circuit board separate from the power substrate module and coupled to the power substrate module via a plurality of conducting pins, the control circuit board being supported on the power substrate module at least partially by the conducting pins, the control circuit board including a drive circuit for generating the control signals to drive the inverting circuit; and

    a plurality of input and output terminal conductors supported on the control circuit board and coupled to the plurality of conducting pins, whereby when the controller is installed between the source and the motor, power is transmitted from the source to the rectifying circuit and from the inverting circuit to the motor via the terminal conductors and the plurality of conducting pins.
