Active Energy Efficiency Using Speed Control

Many motors only have two settings: on and off. They operate at constant speed. If a motor turning at constant speed is driving a device or process that requires less output, adjustments are required to achieve the desired output level. This adjustment is often achieved by letting the motor run at full speed, while using downstream devices to block part of the output.

This is like driving your car by having one foot fully depressing the accelerator pedal, and the other on the brake to constantly control the speed. It sounds absurd, but this is still one of the most common control methods. An estimated 60% of motors are not speed controlled.

The focus of this course is to explore the different ways we can control motor speed efficiently and with minimal physical stress on equipment. In addition, we’ll discuss other advantages such as controlled starting and regulated torque.
