Dc motor impersonators
limits, the torque of a dc motor is a linear function of input current. So it is relatively easy to get solid performance out of a dc motor with standard proportionalintegralderivative (PID) controllers. In reality, the type of motor that works best in any given application depends on many other system...

Copper Shines in Motor Rotors
copper-rotor designs. FAVI doesn't sell in the U.S., but SEW and Siemens copper models first came on the U.S. market about three years ago. The motivation for a copper-rotor design stems not only from efficiency considerations but also from a desire to minimize the size of the motor. "When you make...

Linear AC Motors
by three-phase windings in alternate clockwise and counterclockwise directions around the tube. Other designs are also possible, but few of them are used. There are several important differences between linear and rotary induction motors that bear on selection. Unlike rotary motors, the linear motor...
