Rotary power conditioning solutions recreate the required power by converting the incoming electrical energy into mechanical energy and  then back again into electrical energy through the use of an electric motor driving a generator. The motor generator set absorbs load harmonics and produces a pure sine-wave output, which is ideal for any critical load. A rotary power conditioner offers many benefits including: electrical isolation, load harmonic absorption, pure sinusoidal waveform, filtering, natural commutation, reliability, and long end of life (EOL). Rotary power conditioning equipment also benefits from simplified maintenance, which when coupled the superior reliability  significantly reduces the cost of ownership and eliminates costly power disturbances.

A PS&C rotary power conditioner is ideal for power conditioning applications because of its construction. The mechanical shaft of the motor generator isolates the electrical load from incoming disturbances such as spikes, sages, harmonics, etc. The mechanical shaft is what also allows for electrical isolation – one of the main reasons users choose a rotary solution. Electrical isolation is capable because the motor and generator are distinctly separate with their own carefully grounded frames, which are tied together mechanically through precise coupling. This mechanical separation is the only way to electrically separate the utility from the load.

An added benefit is that a motor generator rides through many short “momentary interruptions”. Typical ride-through capability is 10-30 seconds.This added protection will not protect against sustained outages, but does allow the use of mechanical contactors for emergency bypassing, which is extremely beneficial when faced with the steep costs of not properly shutting down expensive manufacturing equipment.
