Q

Which of the following causes would most likely result in excessively high belt-driven reciprocating air compressor drive motor running current draw?

🔍 Key Concepts

• Relationship between mechanical load and electric motor current draw • How belt tension affects the load on motor bearings and pulleys • How air flow restriction or internal clearances affect compressor power demand

💭 Think About

• For each choice, ask: does this condition make the motor work harder or easier to turn the compressor? • Think about what happens to current draw when the mechanical resistance on the motor shaft increases. • Consider which option directly increases torque required at the motor, rather than reducing it or making compression less efficient.

✅ Before You Answer

• Compare which options would increase mechanical drag on the drive system (belts, bearings, pulleys). • Identify which options would increase compression work (pumping more/denser air) versus which would decrease the amount of air actually compressed. • For each choice, visualize the effect on starting torque and running temperature of the motor and compressor.
