A growing number of manufacturers are saving time and money by testing, diagnosing and even repairing servo motors in-house. We look at the expanded role of encoder test systems and present one ...

Myriad applications require custom torque motors — including hard-machining table drives, mirror millers, and measuring and grinding machines. In fact, machine builders for these applications are now ...

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 ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
