Some of the energy loss of induction
motors can be corrected with a
passive network of capacitors or
However this method does not
capturethe full savings.
All induction motors should only consume and deliver the necessary power to safely drive a load. Any
excess power consumed is considered wasted energy. Any voltage above the required load can be
considered excess energy.
Reasons why induction motors consume excess energy:
1. The motors are sold in fixed frame sizes and are frequently oversized for the application;
2. A motor is selected to safely drive the maximum peak load but is excessive for normal load
operation or varying load;
3. Motors are configured to insure that they will safely operate at minimum low line voltage.
VSquare/R's "Dynamic Power Controller" safely delivers the minimum required power to a load
regardless of load variations and maximizes the electrical energy savings regardless of the voltage.
Our product never operates at full line voltage. It utilizes two  different approaches (power
control/voltage control) to save energy in induction motors.
Power control - A slightly modified induction motor with a tapped winding is used, with a proportional
controller switching between these windings to provide multiple average power levels. The power factor
feedback from the Dynamic Power Controller only delivers the necessary power to safely drive the load.
Voltage control - This approach is used primarily on existing motors in the market place. A proportional
controller switches between voltage levels to provide a multiple of RMS voltages. The power factor
feedback from the Dynamic Power Controller only delivers the necessary voltage or power to safely
drive the load.
