• 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...
• Mathematics of Electronic Motor Control
  , smoothness of motion and a large dynamic operating range are often key requirements. There is one other characteristic of brushless DC motor that have made them attractive to new applications such as electric and hybrid vehicles, which is their efficiency. High performance brushless DC motors driven...
• Application Note: Comparative Motor Technologies
  are friction surfaces prone to wear. 4. Heat build-up causes non-repeatable performance. 5. High repetition rates tend to cause shock loading of prime mover shaft. Stepper Motors. A stepper motor is an electromechanical device that works by dividing shaft rotation or linear displacement into discrete...
• Architectures for Economical Motion
  similar core elements. They need control electronics to calculate the trajectory, power electronics to amplify a control signal and interface to the motor, and connections to hook everything together. Though servomotors need feedback from encoders and brushless-dc motors need Hall-sensor inputs...
• 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...

• Show-biz bots: The Next Act
  compatible signals to another. Such brushless servomotors electronically commutate a wound stator to drive a permanent-magnet rotor. Mannetron found the arrangement better transfers heat to the motor housing for cooler running, an important consideration for the application. Moreover, the integrated motor...
• Getting Swinging Lights to Stop on a Dime
  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...
