Abstract: A system and method for estimating operating characteristics of an induction motor is disclosed. The system includes a motor control device that is electrically connectable between a motor and a power source. The motor control device includes a plurality of switching devices comprising at least one thyristor corresponding to a respective phase of the motor. The motor control device also includes a controller programmed to disconnect the power source from the motor for a predetermined time period following a first plurality of cycles of a mains phase voltage of the power source. The controller is further programmed to measure a back-emf voltage during the predetermined time period, estimate an operating characteristic of the motor from the measured back-emf voltage, and trigger the plurality of switching devices to reconnect the power source to the motor following estimation of the operating characteristic.

Abstract: A system and method for automatically defining and tuning operating parameters for a motor control device with minimal or no operator input is disclosed. The system includes a motor control device electrically connectable to an AC motor and a controller that is programmed to define a motor start-up function based on a rated current of the motor, the motor start-up function comprising an initial torque factor and an initial ramp time. The controller also triggers switching devices of the motor according to the motor start-up function to inject current into the motor during a first trial run, monitors operating conditions of the motor and motor control device during the first trial run, modifies the motor start-up function based on the monitored operating conditions, and triggers the plurality of switching devices according to the modified motor start-up function to inject current into the motor during a subsequent trial run.
