Abstract:
1. A motor drive system comprising: a power subassembly including power electronic switches controllable to provide controlled frequency AC power to an electric motor, and driver circuitry configured to apply gate drive signals to the power electronic switches; and a control subassembly separable from the power subassembly but physically configured to be toollessly attached to the power subassembly and to make electrical connections with the power subassembly when attached, the control subassembly including a user interface and control circuitry that, in operation, applies control signals to the drive circuitry for controlling the power electronic switches, wherein the power and control subassemblies comprise mating multi-conductor connectors that mate when the control subassembly is attached to the power subassembly to convey signals between the power and control subassemblies.
