• AC and DC Motors

    I realize this is "electric motor 101," but just in case you need a refresher, or are curious to see how motors work, I'd recommend this article from John Francis: There are two main types of electric motors. There are direct current or DC and alternating current or AC motors. The reference of DC or AC refers to how the electrical current is transferred through and from the motor. Both types of motors have different functions and uses. Dc motors come in two general types. They can have brushes or be brushless. AC motors, as well, come in two different types. They can be two phase or three phas

  • Variable Frequency Drives: Reducing Costs and Energy Use

    As mentioned before, here and here, VFDs are an excellent means to saving money and extending the life of your motor.  Amanda Griffith breaks out the benefits of variable frequency drives. For example: Variable-frequency drives are the most effective energy savers in pump and fan application. In most facilities, centrifugal pumps and fans run at one speed, with an automatic value, or some mechanical means, varying fluid flow rates. With a variable frequency drive, users can change motor speeds electronically. By adjusting a pump or fan speed to meet only the desired rate needed, one can signi
