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 ...

Open-loop motors previously working in this system elevated the temperature of fluids being pumped into the bioreactor. The higher temperatures, in turn, adversely affected biological processing times ...

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 ...

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 ...

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 — ...

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 ...

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, ...

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.
