• Sinusoidal Commutation of Brushless Motors (.pdf)
  Commutator. +. -. Figure (9)- A Simple brush-type motor. To build a brushless motor, the current-carrying coils must be taken off the rotating. mechanism. In their place, the permanent magnet will be allowed to rotate within the. case. The current still needs to be switched based on rotary position; figure...
• Brushless DC Motors Increase Reliability: Wear-free Direct Drives for Strapping Machine Systems (.pdf)
  or chains; moreover the brushless drives are not sensitive to dirt build-up, as the critical. brush contacts are eliminated. Compared to previous solutions, tests have demonstrated a service life of almost. twenty times longer for these sealing units. In total three brushless DC motors are used today...
• Power and efficiency drive motor selection
  Methods for sizing motors, selecting drives and controllers, and using design rules for reducing cogging torque, help motion control engineers build more accurate, efficient, and reliable systems. Edited by John R. Gyorki, Lawrence Kren, Kathleen Franzinger This family of three-phase brushless dc...
• Architectures for Economical Motion
  are still the dc servomotor, the brushless-dc motor, and the stepmotor. But distinctly different from 20 years ago, and perhaps a little surprising, is that the choice of motor has little effect on the overall cost and architecture of the control system. What used to be the most-complicated...
• Making sense of motion networks
  , brushless-dc, or stepmotors. One such product is the MC58000 Series from Performance Motion Devices Inc. It provides all the usual motion functions such as profile generation, servoloop closure, and commutation, but adds a complete CANbus network connection that simplifies construction of low-cost...

• Mathematics of Electronic Motor Control
  brush motor, which is a single phase device, generating this is done by a mechanical commutator with brushes. In a brushless DC motor, it must be done by the external controller. Figure 1 shows two kinds of force that are generated by the magnetic field interactions. They are known as the Q (quadrature...
• Show-biz bots: The Next Act
  is still viable and Max continues to do trade shows worldwide. But improved servomotors, computers, and software will make Max's successors -- an Illano-type robot (original Illano predates Max) and Sico-8 -- easier to build and operate. Sico-8 is under construction and will be driven directly...
• Application Note: Comparative Motor Technologies
  Sinusoidal Brushless Servo Amplifiers. Application Note : Comparative Motor Technologies. - September, 2003. Air Motor and Cylinders. Air Actuators use compressed air to move a piston for linear motion or turn a turbine for rotary motion. Responsiveness, speed and power (torque) are determined by air...

  6mm to 90mm, and from 30 mW to 500W. They. also offer gearheads, controllers, and accessories. Particularly, flat motors manufactured by Maxon Precision. Motor provide long life along with their low profile. package. The entire EC series of brushless motors are. electronically commutated, which...
