Abstract
A motor control system for induction-type capacitor-start AC electric motors having starting and run windings starts the electric motors on AC power then, without stopping the motor, switches to using a variable-frequency motor drive (VFD) configured with a maximum power point tracking method to run the motor from solar power. In particular embodiments, the MPPT method is adapted to reduce power consumed by the motor by reducing frequency and voltage provided by the VFD when available solar panel power is insufficient for full power operation, and to increase frequency and voltage provided by the VFD when available solar panel power is greater than power absorbed by the motor.
