How does a motor go from having a set speed to increasing the speed in varying ways? Variable speed drives are what you need for taking your motor from a set speed to a varying speed depending on your needs. It changes the controlled speed at which the motor operates.Variable speed drives are highly efficient at reducing your energy needs as controlling the speed keeps you from using motor power unnecessarily. 

A beneficial quality of the variable speed drive is that they help to control the noise generation and can serve you by keeping fans from carrying too heavy a load which can cause a surge. When a load surges it can become unstable. If the fan becomes unstable you can run into problems such as violent pulses. Violent pulses could potentially damage your equipment. Another beneficial quality is that it helps keep the wear on your machinery to a minimum, particularly concerning your bearings and belts. 

Variable speed drives work well not only with fan units, but you will find them useful with pumps.  They help to control the pumps on variable flow pumping systems. They can also control the compressors used in refrigeration where centrifugal chillers are used.

These drives can control motor power by adjusting things such as voltage and frequency. It takes the place of the starter because it can start with the added benefit of overload protection built right in.  It protects against faults with the machinery. Faults can range from things such as under-voltage or ground fault to loss of phase.  You can also program your drive to give you a soft start of the motor. That will protect you from current rushes. It also alleviates wear and tears on belts.
