Abstract:
1. A system for controlling a motor comprising: a voltage source; a motor in operable communication with an inverter, said motor responsive to a command signal from said inverter, said inverter is in operable communication with said voltage source and a controller, wherein said inverter includes a plurality of switching devices configured to receive a command from a controller and generate a voltage command to said motor; and a voltage sensor for detecting a voltage of said voltage command to said motor at a selected instance; a controller in operable communication with said inverter and said voltage sensor; said controller configured to provide a command to said inverter responsive to said voltage of said voltage command to said motor at a selected instance; further including a current sensor in operable communication with at least one of said motor and said inverter, said current sensor transmitting a current signal to said controller indicative of a current utilized by said motor, wherein said command is further responsive to said current signal.
