These units do not use phase convertors,but a true 50 hp single-phase electric motor. SPPS Written-Pole 50 hp single-phase motors can power anything  powered by an equivalent horsepower stationary internal combustion  motor or three-phase electric motor. Our 50 hp motors are used in manufacturing, agriculture, irrigation, oil & gas industry and even small municipal pump stations.
