چکیده
Cyclic vibratory torque requirement of a Reciprocating Compressor sets in torsional vibrations in compressor motor system. Explanation of development of pulsating currents, due to vibratory motion of motor rotor is given. The pulsating currents are superimposed on steady state currents. Mathematical mod~ls for analysing torsional vibrations of the system and nett motor current due to combination of steady state and pulsating-currents is explained. Stepwise procedure for calculating instantaneous line current over a period for few revolutions of compressor and subsequently current pulsation is given.

In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...
