Premium-Efficiency Motors and Variable Frequency Drives

For our business customers in Iowa

Electricity accounts for up to 97 percent of a motor's lifetime cost. As a result, purchasing a NEMA Premium® efficient motor for your business makes sense in almost every situation:

• When an existing motor is inefficient
• When an existing motor fails
• When installing a new piece of equipment

With rebates up to $1595 per qualifying unit, your investment in a premium-efficiency motor is even more cost effective. It's wise to take action before motor failure strikes (and you are forced to chose the quickest replacement, and not the smartest, most energy efficient replacement).

Invest in a high-efficiency premium motor today and take advantage of the following rewards:

• Reduced energy expense
• Enhanced operational efficiency
• Lower maintenance costs
• Less unscheduled downtime

Consider installing a variable speed drive if your motors are used for extended periods and have a higher variability of loads on the system (centrifugal pumps and fans) or if the application of use includes mechanical throttling (valves, dampers, etc.).
