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 ...

William Sturgeon, an English physicist who invented the electromagnet, a coil of wires around an iron core used to enhance the magnetic field, also invented the first DC (direct current) motor that ...

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.

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 ...

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.

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 ...

Strategies To Avoid Stepper Motor Resonance Problems When an application requires a reliable, low-cost motor with simple operation, stepper motors can be hard to beat. They can be driven step by step ...
