OIL & GAS INDUSTRY APPLICATIONS


RECIPROCATING COMPRESSORS

MOTOR DESIGN CONSIDERATIONS

Oscillating currents Torque pulsations Speed variations – (degree of irregularity) High inertia – (inclusion of flywheel to limit

effects

of the above) Need for a rugged frame construction Preference for large centre height / short core

length (D2L) in design Forged shaft to better accommodate the effects

of the pulsating torque Integrally forged coupling flange High degree of construction necessary in rotor

cage Winding bracing to withstand oscillating currents
