Introduction

Better efficiency

Compared with the ordinary motor, efficient means for the same energy input, the motor itself less power loss, and output more, also, because the motor itself lost less energy to flow, energy conditions required in the same workload, the motor input power will be reduced, so as to cut the energy consumption and running cost.

Partial load is more efficient

Most motors are rarely working under 100% full load conditions. Thus, it is important that the nominal power of the motor is in the case of a full load. For general motors, the efficiency is generally do not provide this data but the efficiency must be 75% Grundfos motor load and 100% load. For the two Grundfos motor, the efficiency value is usually the same.

Motor operating temperature is low

Because of the high efficiency Grundfos motor with energy loss, the heat generated is very small, so when the motor is stable than ordinary motor working in low temperature. As a result, a high efficiency motor can work at a higher ambient temperature, and the required ambient cooling requirements are lower than the standard normally used.

Similarly, the motor stator windings of the motor stator windings can also be kept in a normal range, and the motor stator windings are rarely overheated. In this way, the motor stator winding insulation and the motor bearing service life will increase.

Low noise

In general, the noise of the motor is mainly generated by the cooling fan. For the motor, because of higher efficiency, less heat generated by the energy loss, used to reduce the temperature of the motor is required to cool the fan is smaller, resulting in noise will be reduced.
