In most applications, electric motors have been specified that exceed the requirements .for normal operating loads that will be encountered. Induction motors draw nearly full load current regardless of the actual requirement. Running over sized or partially loaded motors at reduced voltage and current decreases energy consumption while preserving normal motor operation. This process is achieved with the installation of Electronic Motor Controllers and Variable Frequency Drives.

Excess current is averted by continually monitoring load shifts in the motor and adjusting current and voltage to match the workload. Solid State Motor Controllers feature soft start and surge defense functions to protect motors from stress caused by sudden starts or from voltage disturbances in distribution lines. When excess current is eliminated, motor operating temperatures are much lower and maintenance costs are reduced over the life of equipment. A partial list of uses follows:

• Fan Coils
• Air Handlers
• Kitchen Equipment
• Cooling Tower Motors
• Refrigeration Compressors

Most motors consume 100 times their initial cost in energy during their lifetime. Purchasing only the highest efficiency motors available will provide a return on investment within months in many cases. This practice will substantially curtail our growing energy demand and will contribute to reversing the pollution and environmental degradation we have fostered on a global level.
