Latest Patents

James Lawton holds a patent for a control system designed for reluctance motors driving loads. The patent describes a system where the output of a reference waveform generator is applied to a power converter through a current controller. The generator's output is determined by rotor position, as detected by a sensor. This system establishes a relative magnitude for motor phase current for every rotor position during the energization period. Additionally, a further control input can determine the absolute magnitude of the motor phase current, subject to the waveform pattern established by the generator. The reference waveforms may be sinusoidal, and a method for determining suitable reference waveform configurations involves monitoring selected parameters of motor operation while controlling others in a test procedure.
