Sentence examples for motor efficiency is from inspiring English sources

The motor efficiency is assumed as 80%% (Fadare et al. 2010).

Because the motor efficiency is directly proportional to the fluctuation ratio of gearbox torque, many researchers designed many types of energy-saving devices to improve the system efficiency.

In general, motor efficiency is implicitly determined by motor power while pump efficiency is given as a function of water flow rate.

({R_{mathrm{a}}}) is the armature resistance, while ({R_{mathrm{h}}}) is equivalent resistance for power losses due to the air resistance of rotor and power loss due to the friction between mechanical parts, and Ma had pointed out that the ({R_{mathrm{h}}}) should be included when the motor efficiency is calculated [11].

First, motor efficiency is regressed as a function of motor power by consolidating multiple dependent factors, then pump efficiency function is reconstructed with pump shaft power and head, and finally experiments are conducted to develop and validate a virtual pump water flow meter on a chilled water pump.

The factors that affect motor efficiency are: shape of lamination, use of high nickel steels is counteracted by poor thermal conductivity, and winding must be litz wire and vacuum impregnated to ensure good thermal conductivity.

Pump and motor efficiencies were taken as 77.9 and 89 %, respectively, from the specification of the originally selected submersible pump.

The match between the motor and fan efficiency is directly related to the work condition of the fan.

Moreover, using the above equations, the motor efficiency that is considering ({R_{mathrm{a}}}) and ({R_{mathrm{h}}}) and that of only considering ({R_{mathrm{a}}}) is shown in Fig. 4 with the same parameters in Table 1.

Piezoelectric motors made with piezoceramics whose efficiency is insensitive to size are superior in the micro-motor area.

Induction motor (IM) variable speed drive efficiency is essential for a few reasons as energy conservation, economic saving and lessening of ecological contamination.
