  1. AC Induction Motors

    In a single year, a fully-loaded motor operating continuously can consume energy worth about 10 times its initial cost. That's why even small improvements in efficiency can pay back quickly. Learn how to choose an energy-efficient motor and successfully integrate it into your drivepower system.

  2. Making Motor Repair or Replacement Decisions

    Many facility managers believe it is cheaper to repair failed motors larger than 15 horsepower than to replace them. However, there are a number of scenarios where replacement with an energy-efficient motor actually makes more economic sense. This article explains how to tell the difference.

  3. Planning for Motor Failure

    The second time a motor fails in an industrial setting is often when facilities managers decide to replace it. The financial and environmental ramifications of this (often rushed) decision can be huge. Learn how to create a motor maintenance plan so you can make the best replacement decision.

  4. Variable-Frequency Drives

    In the right applications, variable-frequency drives can increase energy efficiency in motor systems by over 50 percent while improving power factor and process precision. Find out which systems offer the largest savings, and find out how to make the best choice.

  5. Voltage Controllers

    If your facility employs alternating-current induction motors that require constant speed but operate for long periods at low load, you may be able to save energy by installing a device known as a voltage controller. This article explains the various options and how to make the best choice.
