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, ...

The first installment of this two-part series focused on debugging brushed-DC motor systems. Now the second installment will share some tips for stepper motor systems and provide general bench testing ...

Rotary motor motion is usually converted to linear through rack and pinion sets, belts and pulleys, and other mechanical linkages. These are effective Rotary motor motion is usually converted to ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

In this post I would like to briefly share my thoughts on a stepper motor tester module I purchased a few weeks ago. The cheap module I purchased is the Makerbase MKS ...

In this EDN Magazine article, K. Suresh of the Indira Gandhi Centre for Atomic Research describes a multiple-stepper-motor-control circuit that uses an ADC to control multiple stepper motors. The ...

Piezoelectricity—the characteristic of certain solid materials whereby electric charge accumulates internally and is released when the material is stressed—was discovered by Jaques and Pierre Curie in ...
