Reciprocating compressors experience high-cyclic loads. Their performance and reliability rely on a robust, severe-duty compressor train. It is important to choose the right electric motor to help control any fluctuations and torque oscillations to minimize fatigue and increase the reliability of the compressor.

​

To best meet these application challenges, our motors have these key features:

​

• High strength AISI 4142 steel to handle current pulsations and torsional vibration

• Oversized shaft diameters matched to compressor shafts for optimal coupling and reliable operation

• Torsional and current pulsation data available

• Keyless shaft extension

• Optimized frame design for low noise and vibration

• Durable, moisture resistant insulation system excels in VFD applications meeting and exceeding NEMA MG1-31 standards.
