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 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 ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

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 ...

Even veteran engineers often suffer from a lot of misconceptions about stepper motors and how to drive them. This article will focus on clearing up just a few of these misunderstandings so that ...

Before choosing between a two-phase or five-phase step motor, take a closer look at the application's requirements and the motor's capabilities. More is not always better, but more phases certainly ...

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.

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

Several different styles of stepper motors in different NEMA sizes. CNC machine centers offer many benefits over manual machining such as greater productivity, precision production, and reduced labor ...

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, ...

Said to be fabricated from the best radiation-resistant materials available, the RH series radiation-hardened step motors are now available in seven standard frame sizes: 5, 11, 15, 17, 23, 34, and 42 ...
