Stepper motors are DC (direct current) electric motors designed for precise motion control. They consist of multiple sets of coils and magnets which are designed to allow rotor movement in angular ...

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.

All of the motors measure 21mm from front to back, plus 8mm of shaft protrusion. In each case there is a standard and a higher holding-torque variant, for example: the 42mm 200mNm HS17HX7L4100 and its ...

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These chips ...

There is increasing demand from engineers and specifiers working on complex motion control applications for cutting edge motors, especially those requiring high-torque, precise positioning and ...

Here is an example of a bipolar stepper motor. (Source: pixabay.com) In this article, we are talking about bipolar stepper motors as they are by far the most likely to be encountered by an engineer ...

Stepper motor drives are devices used to power and control stepper motors. While some basic drive units only supply power, many commercially available drives also incorporate controller electronics ...

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.

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, ...
