Process Motor Sizing

 
The main motor driver for Process compressors will typically be a direct coupled electric induction motor or direct coupled electric synchronous motor.  Motor nameplate horsepower must be 10% greater than the maximum operating horsepower or greater than the discharge relief valve set point condition, whichever is greater.
 
Motor driven reciprocating compressors typically require a torsional response analysis, current pulsation analysis and starting torque analysis.  These studies will determine final coupling selection and if a flywheel is required.
