What are Ride-Thru Motor Generators:

Series IMG-RT & SMG-RT

Ride-Thru Motor Generator

Power conditioning systems from Power Systems & Controls are the perfect solution for industrial and commercial power users.  Research shows that most power quality problems are the result of sags or power losses of a very short duration.  Due to these sags, PS&C designed Ride-Thru Motor Generators.  As a result, a UPS is no longer the only option to keep the power on.  Furthermore, there is no need for batteries, with this technology.

Statistics indicate that each month, a typical user faces a 90% probability that their facility will experience a sag that will go below 80% of nominal. As for the threat of outages, the statistics are heavily weighted toward interruptions of 2 seconds or less.  Worse than the outage itself, these interruptions effect the manufacturing processes.  Therefore, this will lead to diminished productivity, wasted materials, and costly cleanup of process lines and equipment.



  • 2 & 4 Bearing Solutions
  • Vertical & Horizontal Configurations
  • Control & Fault Monitoring
  • 100% Electrical Isolation
  • Synchronous & Induction Motors

The "Ride-Thru" Motor Generator Sets integrate state-of-the-art controls, a single shaft motor generator and a mechanical flywheel into a power conditioning system that can deliver up to 5 seconds of "ride-thru" during an interruption of power.  The typical M-G Set delivers this ride-thru with a maximum frequency drop at full load of no more than 57Hz on a 60Hz system.

For sensitive applications where tighter tolerances are required we have the Series SMG, but for more economical projects we also have our Series IMG-RT.  The SMG-RT has a synchronous motor while the IMG-RT has a cheaper induction motor.  Ride-Thru Motor Generators are available in sizes ranging up to 2000kVA for low voltage applications; however, we also offer medium voltage solutions.  Systems come in either horizontal or vertical configuration.  Additionally, systems can be customized to meet any application requirements of the user from ride-thru capability to frequency tolerance.
