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.
