Synchronous Motor Generators:

Series SMG

Synchronous Motor Generator

Power Systems & Controls' Series SMG was designed because we needed to provide 100% electrical isolation for your downstream equipment.  Due to its design, the Synchronous Motor Generator is mechanically coupled and electrically isolated from the utility feeding your facility. It was developed to provide critical equipment with clean and conditioned power.  As a result, the Synchronous M-G Set will also reduce voltage transients, protect against voltage sags and reduce flicker.  In addition to correcting for rejected harmonics, stopping electrical disturbances, and creating a perfect sine wave.  Subsequently, this will reduce the problems associated with harmonic distortion.



  • 100% Conditioned Power
  • Eliminate Power Disturbances
  • 100% Electrical Isolation
  • Connected to Synchronous Power
  • 5 to 8 Cycles of "Ride-Thru" Time
  • Vertical & Horizontal Configurations
  • Long System EOL

The Series SMG is a brushless synchronous motor generator set with a precision solid-state voltage regulator.  The regulator is there to maintain the voltage within (+/- .5%) from nominal.  It also has PLC controls and internal fault monitors. In addition, a touchscreen interface was added to simplify all operator controls and gives the user complete control over the system. The Series SMG has electrically operated input and output circuit breaker, as well as, voltage and frequency detectors to protect the system against short-circuit or overload scenarios. In addition, the bearings are protected from over temperature due to detectors integrated into the SMG's design.

The synchronous motor generator is of all steel construction and has anti-friction bearings throughout to help guarantee an end of life (EOL) of well over 20-30 years.  Additionally, as an added benefit the Series SMG has inherent power factor correction.  Another benefit of PS&C is our ability to offer "turnkey" installation for any project worldwide.  There are many standard options for the SMG.  However, there are options for remote communications and possible outdoor rated enclosures.  These range from NEMA1 to larger ISO enclosures.

If you do not need the synchronous style motor generator, our Series IMG (Industrial Motor Generator) solution will offer the same PS&C performance, at a lesser cost.  Finally, if you find yourself needed more ride-thru, PS&C has a solution.
