• Getting to know stepper motors
  and computing power, it's easy for biomedical engineers to design stepper-motor-based solutions for medical equipment that must meter, dispense, or pump fluids. They can also use stepper motors to build analytical gear with motion control needs. Stepper-motor systems provide precise speed, position...
• 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...
• 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...
• Software models motors in 3D
  the search. lt uses finite elements to model 3D fields in both translating and rotating electromagnetic devices. Claw-pole alternator/motors, for example, have highly 3D geometry and cannot be modeled in 2D. Previous analyses assumed a stationary rotor and currents that were all known and dc. Those...

  for electric bikes outside of Japan, according to Alex Campbell, spokesman for Zapworld.com. In 1996 the company received the first of many patents for its electric motor system. The ZAP (which stands for zero air pollution) power system includes two permanent-magnet, brushed dc motors, a battery...
• Servomotors Stabilize and Position Sensor Turrets on UAVs
  the visible-wavelength imagers come equipped with motorized focus and zoom, the IR turrets incorporate brushed-dc motors from MicroMo for their focus mechanism. Some of the IR imagers also have motorized zoom. Meeting the stabilization and control specs would be difficult enough on the ground...
• Fab it Now
  resin. “After a few trial runs, the fabber printed a battery about the size of a coin and with five layers of different material in a plastic case,” says Lipson. “In one test, the device delivered 10 milliwatts for 50 hours to a small dc motor. While not performing as well as a commercial unit...
• How tight is right?
  of these metrics in pretightened fasteners. Here's how it works: A computer-controlled dc electric-motor drive inputs to a torque-angle sensor. The sensor output shaft couples to a fastener (bolt portion) to be tested while a research head traps the nut. The research head contains a torque sensor...
