Can a three-phase AC motor drive connect to a single-phase power? The greatest difference among Delta single-phase and three-phase AC motor drive is the power capacity. Single-phase model is designed for greater power capacity. If a three-phase model is connected to a single-phase power, it may not provide enough output current and may cause a phase loss problem. To ensure a normal system operation, please connect three-phase AC motor drive to the accurate power source.
