Technical Information
Select any of the items in the table below to learn more detailed technical information about motor efficiency and operation.
| POWER FACTOR | There may be a variation in power factor between an old motor and its new replacement. Learn more by comparing a range of old and new motor power factors. |
| EFFICIENCY STANDARDS | Learn more about the Minimum Energy Performance Standards (MEPS) programme managed in New Zealand by the Energy Efficiency and Conservation Authority (EECA). |
| REWINDING EFFICIENCY | Learn more about the impact on efficiency of rewinding electric motors. |
| MOTOR SPEED | When you replace a motor there may be a small change in motor speed. Learn more about the energy impact of replacing an old motor. |
| NEW MOTOR DATA | There are two primary sources of motor efficiency data – motor supplier catalogues and government funded websites. There can be variation between these sources – learn more here. |
| OLD MOTOR DATA SHEETS | Efficiency data was not regulated prior to 2002 and the data can only be taken at face value. Learn more about the efficiency data for old motors from catalogues available to motor purchasers at the time. |
