• Introduction to Electric Motors
  . On the other hand, machines with flywheels may have wide variations in running loads. Often, the flywheel supplies the energy to do the work, and the motor does nothing but restore lost energy to the flywheel. Therefore, choosing the proper motor also depends on whether the load is steady, varies, follows...
• WD Bearings Application: Electric Motors
  to systems where the feedback or error-correction signals help control mechanical position or other parameters. For example, an automotive power window control is not a electric motor, as there is no automatic feedback which controls position--the operator does this by observation. Stepper Motor...
• Software Review: FEA for Electric Motors
  products such as hard-disk drives, power tools, and digital cameras. We also manufacture automotive sensors, and accessories such as seat-position motors. But a downside to FEA is that building models can take a lot of time. And other analytic software for motor design does not provide enough...
• How to speed up dc motor selection
  Recent advances in electric motors and controllers improve their speed, acceleration, controllability, and reliability, while allowing designers a wider choice of power and torque. Selecting a fractional hp dc motor is easier when you know how to handle motor constant . Guidelines used by experts...
• South Texas Electric Co-Op Power Plant
  Manager, Jim Bell. Client: South Texas Electric Co-Op. Application: Power Plant. Location: Pearsall, TX. Equipment Summary: (25) 54” Filtered Wall Supply Fans with Rainhoods, Birdscreens & Filter Box with Hinged access doors & motor operated dampers. Interior 2-Way Diffuser. Adjustable Frequency...
• How VFDs Save Energy
  that a VFD has is the ability to save the user money through its inherit nature to save energy by consuming only the power that's needed. The main question now is, How does a VFD accomplish this? The simple answer to this question is power conversion. A VFD is similar to the motor to which it's attached...
• Brushed DC Motor Fundamentals
  Brushed DC motors are widely used in applications ranging from toys to push-button adjustable car seats. Brushed DC (BDC) motors are inexpensive, easy to drive, and are readily available in all sizes and shapes. This application note will discuss how a BDC motor works, how to drive a BDC motor...
• China ups the motor ante
  to do with economic and political factors. For one thing, how does a formerly communist system with a legacy of centralized government planning handle an emerging free-enterprise system? Right now, there are still state companies with government funding competing against free-enterprise companies...
• Understanding Electronic Motor Drives
  waveform. The smoother the dc waveform, the cleaner the output waveform from the drive. The dc bus feeds the inverter, the final section of the drive. As the name implies, this section inverts dc voltage back to ac. But, it does so in a variable voltage and frequency output. How this happens depends...
• A Perspective on Piezo Motors (.pdf)
  will create a filter that will smooth out the signal. OK, so how does the motor actually work? Well, there's several ways to achieve motion using the reverse. piezoelectric effect. The ideas we are talking about apply to both rotary motion and linear motion. Generally speaking,. it involves...
