There are several varieties of stepper motors, having somewhat different types of commutation and operating characteristics, but they all have in common the ability to spin continuously in either ...

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 produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

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 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 ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

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 ...

A new design technique produces corrosion-proof and waterproof stepper motors, extending motor life in harsh outdoor conditions. Electric motors used outdoors are susceptible to temperature extremes ...
