Brushed-dc and Piezo Motors Combine for Precise Position
in small increments, the payload moves slowly from position to position. While perfectly fine for taking measurements, it may take several minutes to move the payload into proper measuring position, with a corresponding loss in production. On the other hand, dc servomotors can move things quickly

Mini footballers run on dc micromotors
. Switching off the appropriate motor changes the robot's direction. The motors with integrated encoder work with matching metal planetary gearheads. The field players, which must quickly cover larger distances, have a smaller gear reduction (14:1) than the goalkeeper (19:1). Despite the small playing field

Torque motors do the trick
to frame sizes for conventional brushless-dc servomotors. For each diameter, there are several axial lengths, so engineers have a range of sizes to satisfy torque requirements for given applications. A torque motor is part of this rotary table Torque motors have been around since at least 1970

Gearhead Construction and Use
to reconcile motor encoder counts with gearhead shaft position only to find a small but persistent position error. At first glance, the use of non-integer gear ratios appears to have no apparent purpose (with the possible exception of frustrating servo designers). There is a fundamentally sound reason
