The Portescap 42S048 can stack stepper motors offer a 7.5° step angle and up to 7.2 oz-in. of holding torque. Available with unipolar or bipolar construction and sintered bronze-sleeve bearings, the ...

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 ...

Step motors are a natural choice when design specs call for low-cost automation with accurate, open-loop control. But finding the right stepper for a given application can be a challenge. There’s a ...

Hybrid stepper motors combine the operating principles of variable reluctance with permanent-magnet stepper motors. The rotor shaft holds one or more pairs of stacked laminations containing many teeth ...

Allegro’s A3901,the first device in a planned series of low-V motor drivers targeted at the portable market, is a dual H-bridge low-V motor driver capable of operating one stepper motor or two DC ...

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, ...
