  • Motor controller and motor assembly
    Patent number: 8378616
    Abstract: Apparatus, having multiple motor modules, has an MCU module. Each motor module has an electronically controlled motor. The MCU module has an MCU and an interface for connecting to a bus from a CPU. In use the MCU module receives control signals from the CPU and in turn instructs a selected one of the motors to operate.
    Type: Grant

  • Method and system for controlling a synchronous machine over full operating range
    Patent number: 6407531
    Abstract: System and method for controlling a synchronous machine are provided. The method allows for calculating a stator voltage index. The method further allows for relating the magnitude of the stator voltage index against a threshold voltage value. An offset signal is generated based on the results of the relating step. A respective state of operation of the machine is determined. The offset signal is processed based on the respective state of the machine.

  • Method of synthesizing poly-phase AC voltage
    Patent number: 6005783
    Abstract: A three-phase invertor and control is disclosed for synthesizing low harmonic content AC voltage in the non-linear, or overmodulation, region of inverter operation. A field orientation control provides a reference voltage vector representing the desired AC output voltage in magnitude and angle. Three state, two state, and step inverter operations are used individually and in combinations in accordance with magnitude and angle parameters of the reference voltage vector.
