AC vs. DC vs. EC  Difference of AC, DC and EC motors.pdf

  • All electric motors serve the same function of converting electrical energy into mechanical energy, but they accomplish this in different ways.
  • The method used depends mainly on the power supplied to the motor, as this affects the way their magnetic fields are created and controlled.
  • For this reason, motors are often categorized as being AC, DC, or EC.
  • In the fan industry, common types of each include the AC induction motor, DC brushed motor, and EC permanent magnet motor.



Why Choose an EC Fan

The benefits of EC fans are clear, so the decision to upgrade often comes down to the payback period. This can only be determined after an analysis has been completed by a professional energy consultant. The financial benefit of an EC fan upgrade needs to be evaluated on a case-by-case basis. However, the following results can generally be expected:

  • The lower the efficiency of the fan being replaced, the faster the payback period will be.
  • Replacing fans that are used frequently will provide higher savings than upgrading fans that are only used moderately.
  • EC fans are an attractive option for applications that require speed control. Other types of motors suffer a drastic reduction in efficiency at partial speeds.
  • The energy savings are higher when fans with EC motors are deployed in air-conditioned or refrigerated spaces.

EC technology combines the advantages of AC and DC motors within a compact, yet versatile, package. The integrated electronics ensure optimal efficiency, even at partial load, which represents a significant opportunity to save on operating costs. Implementing one of the built-in control methods is the best way to take full advantage of all the benefits that EC fans provide.
