A new approach to position control based on microstepping with nonlinear torque modulation for permanent magnet stepper motors is studied. The proposed method comprises nonlinear torque modulation, a ...

This article proposes a robust nonlinear position control for permanent magnet stepper motors. We develop a new single-input single-output model that consists of position, velocity, and acceleration ...

Among the many innovations of the last 30 years are greater efficiency for induction motors, standardization of design, optimized two-pole design to meet noise requirements, growth of brushless ...

The SonaSpeed’s simplex permanent magnet stepper motor is used in the actuator assembly of the LVM 3 for controlling the rocket engine’s liquid fuel and oxidizer mixture ratio.

Here are tips for debugging stepper motor systems as well as general bench testing advice based on the personal experience of co-authors.

For these motors, “hybrid” refers to how they use a permanent magnet and a toothed iron rotor—for instance, a variable reluctance motor—and “200 steps” means that the motor moves 1.8° between each ...

Downsizing The PKP Series stepper motors provide torque equivalent to a stepper motor of the next larger frame size, contributing to downsizing of equipment. Utilizing Hybrid Stepper Motor Technology ...

Stepper motor phases are commutated sequentially by an external electronic driver that subsequently moves the rotor—which often carries a permanent magnet—from one stable position to the next.
