Calculates electric motor efficiency comparing input power to useful mechanical output. Identifies opportunities for energy savings.

ସୂତ୍ର

Efficiency = output ÷ input × 100%

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Measure input power (watts)
  2. 2Determine shaft load and speed
  3. 3Calculate output mechanical power
  4. 4Efficiency = output ÷ input × 100%
  5. 5Typical industrial motors 85-95% efficient

  • Assuming all motors equal efficiency across speed range
  • Not considering part-load efficiency (motors inefficient at low load)

ବାରମ୍ବାର ଜିଜ୍ଞାସା

Why do motor speeds vary if efficiency is similar?

Motor slip determines actual speed; typical slip 1-10%; affects torque and efficiency.

How do I improve motor efficiency?

Match motor size to load (oversized motors run inefficient), reduce friction, improve cooling.
