The Importance Of Motor Dynamics In Reciprocating Compressor Drives


Published:

Investments in further developing the North American natural gas supply continued at a strong pace in 2013. Major investments are being made to process, transmit and store the new gas supplies.

The need for highly accurate torsional analyses to produce the most reliable drivetrain is paramount to achieving best-in-class uptime.

The use of electric motor-driven compression continued to increase 2013, a trend which is primarily being driven by availability of electricity, cost of electricity, emissions regulations and the strategies of end users.

When utilizing motor-driven drive-trains, proper torsional dynamics and system analysis should lead to:
