A pony started single phase driven 3 phase motor without any phase correction easily delivers its full rated HP at a few % lower than its rated speed. For long term use, Brook Compton Parkinson motors data shows that rated full load current is reached in the single phase driven lines at roughly half full rated load. This is still below rated full load dissipation because the current in the indirec Most of this power reduction can be recovered by a single phase correction capacitor chosen for best phase balance near full load.
