Stepper motor systems are highly efficient when producing torque, but lack operational efficiency when not producing torque. Applied Motion Products offers insights on how to make a greener and more ...

Applied Motion Products solved heat problems associated with a peristaltic pump system that supplies materials to a bioreactor by replacing open-loop step motors with closed-loop step motors. A ...

Combining a high-torque step motor with an on-board drive, encoder, controller and closed-loop servo software into a single package, the integrated motors save on space, wiring, and cost over ...

Open-loop stepper motors have held a prominent position in automation applications over the years due to their simplicity, excellent positioning, and low cost. However, as manufacturers utilize faster ...

The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

Not missing a beat: Here we take a look at why open-loop steppers lose steps, as well as some solutions to the problem. As in the below) half-stepping produces eight steps per electrical rotation — ...

Available in three versions, the MAE hybrid step motors deliver accurate open-loop control for high-performance positioning applications. The Y Series models come in sizes 16, 17, and 23, and ...

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to ...

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, ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

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.
