No, it is the easiest of all types to install, comparable to installing any electric motor. A disconnect switch or magnetic starter is needed to start the converter and the single phase wiring must be adequate to handle the current of all the motors to be operated. It must be emphasized that our wiring recommendations should be carefully followed. The roto-phase can last longer than the motors and equipment being used. It is never more than lightly loaded and very cool running under load.
Temperature rise is greatest under no-load condition.
We make no claims on savings on electric bills because kilowatts used will be the same whether motors be single phase, three phase, or three phase motors operated through roto-phase. Their study also revealed that no single phase motor or three phase drying installation had a per bushel electric cost as low as this. The high efficiency of the roto-phase distribution system largely accounts for this. The roto-phase has about the same list price as some static converters. Against the medium size single phase motors the price is very competitive, again, the single phase motor does only a single job.
