IE Efficiency Classes for Motors

The IE (international efficiency) efficiency classes: IE1 = Standard Efficiency IE2 = High Efficiency IE3 = Premium Efficiency Less power consumption brings costs down Change-over to energy-efficient motors pays off because they reduce energy consumption substantially and thus cut operating costs. Whatever requirement you need to meet, we have the right energy-efficient motor for you as part of our portfolio. IE3 motors from Siemens: much more than just thrifty The main objective of the IE3 Standard, is to achieve a lasting reduction in energy consumption of electric motors that are operated direct on line and ultimately to make a contribution to...

Constant vs Variable Torque

VARIABLE TORQUE LOADS:Many types of loads require reduced torque when driven at speeds less than the base speed of the load. Conversely, such loads may require increased torque when driven at speeds greater than the base speed of the load. These are classified as variable torque loads. Many variable torque loads decrease with the square of the speed. This is characteristic of centrifugal pumps, and certain types of fans and blowers. Typically, as the speed decreases, the torque decreases with the square of the speed and the horsepower decreases with the cube of the speed.CONSTANT TORQUE LOADSWith constant torque loads,...

What are the benefits of installing a VSD?

A variable speed drive controls motor speed and torque by varying the motor input voltage and frequency. A very close match between motor speed and the output requirements of the machine it is driving may therefore be achieved. Variable Speed drives offer the user a number of advantages including: Energy savings Elimination of expensive mechanical drive components Increased motor longevity Reduced power line disturbances Reduced risk of motor damage during start up and stop The energy savings alone can often justify the cost of purchase and installation of a VSD. Unfortunately, most of these advantages may be compromised by poor...
