It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

The Rock-Tenn paperboard mill in Aurora, Ill., automated the positioning and tensioning of belts on its conveyor system with low-cost motors and drives paired with absolute encoders. When the ...

Alignment of optical encoder commutation signals to a Brushless DC (BLDC) motor could be thought of as being comparable to timing the distributor on a car engine. The distributor tells the spark plugs ...
