Energy Efficient Motors

Generally, the term energy efficient motor refers to maximizing the product of efficiency and power factor of a motor.
i.e. Max (efficiency X power factor)

High Performance Motors

This class of Energy Efficient motors has higher efficiency and higher performance values (speed, torque).

  1. Motors with least energy consumption
  2. Higher speed (rpm)
Most Suitable for Textile Industry

High Performance motors are most suited to Textile Industry where motors are required not only to consume less energy but also, at the same time, give increased production.
Hence, High Performance motors have twin advantage:

  1. Savings in power cost
  2. More production*

IEEMA Standard for Energy Efficient Motors

This standard is prepared with “energy conservation” as the major requirement. It follows the philosophy of categorizing motor efficiencies at three levels – i.e.

  1. Low efficiency – (eff 3)
  2. Improved efficiency – (eff 2)
  3. High efficiency – (eff 1)

To conform to this standards and eligible to be considered as energy efficient, the motors shall meet the minimum norms of eff 2.

HHigh performance motors should have efficiency conforming to eff 1.
