When quality of Electric Motors matters.
Welkon Limited

Plot Squirrel Cage Induction Motor Efficiency in relation to Motor Loading (Percentage of the Load at DOL Connection).
The Efficiency accross the speed range when the Motor is Inverter Controlled will also be displayed.
Assumptions:  Standard PWM (Pulse Width Modulated) Inverter is used for Constatnt Torque load application.
Please enter Catalogue/DataSheet published Efficiency values at 100%, 75% & 50% Load and the Rated Speed in the Table below the graph.


For DOL: Percentage of Load = 0 % —>         
For VSD: Speed Controlled at 0 rpm —>         
Enter Motor Efficiencies & Rated Speed:

100% Load 75% Load 50% Load
Rated Speed [rpm]
