Latest Patents

Donovan Gray holds a patent titled "Methods of protecting motors driven by variable frequency drives and variable frequency drive systems employing the same." This patent describes a method where a converter of a variable frequency drive operates in a ramp-up mode to produce an AC output voltage for accelerating a motor. The loading of the converter is determined concurrently with the ramp-up mode. The transfer of the motor to a bypassed mode is conditioned on whether the determined loading in the ramp-up mode meets a specific criterion. In some embodiments, conditioning transfer to the bypassed mode involves foregoing the transition based on a comparison of the determined loading to an underloading threshold. This innovative approach aims to improve the reliability and performance of motor systems.
