Motor Generator Sets provides the clean power required by industry by passing the incoming electrical power into a motor and  then back again into clean and conditioned power through the use of a synchronous generator. The motor generator set absorbs load harmonics and produces a pure sine-wave output, which is ideal for any critical load. A motor generator set offers many benefits including: electrical isolation, load harmonic absorption, pure sinusoidal waveform, filtering, natural commutation, reliability, and long end of life (EOL). Motor Generator Sets also simplify maintenance needs and programs, which when coupled with the superior reliability, offers a significantly reduced cost of ownership and eliminates costly power disturbances.

A PS&C motor generator set is ideal for power conditioning applications because of its simplistic construction, when compared to equivalent static power conditioners.  However, the mechanical shaft of the motor generator isolates the electrical load from incoming disturbances such as spikes, sages, harmonics, etc – which is cannot be achieved with static power conditioners. 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 set rides through many short “momentary interruptions”.  Typical ride-through capability with additional mechanical mass is 1 – 5 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.
