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 ...

The application of a disturbance observer (DOB) and a variable structure controller (VSC) to current control of microstepping for permanent-magnet stepper motors (PMSMs) is studied. This is a recent ...

However, although the motor torque has been improved, the cogging torque still affects the output torque of the motor. This paper describes a method to reduce the cogging torque of the permanent ...

Permanent magnet motors (PMM), in particular, and emerging digital technologies in general are innovative and adaptive technologies that can help address those needs. Q: What are the major differences ...

Using just a magnet, a battery, a nail and a piece of copper wire, this is the simplest electric motor you can make, says Alom Shaha, but it is utterly delightful and children will love it ...

It analyzes the motor in place and can visualize what’s happening during stepping, microstepping, and other operating modes. Connecting the instrument is easy since you just use a four-pin pass ...

When it comes to selecting across different types of motors, reliability and efficiency are two of the most important factors to consider. Among the choices, permanent magnet AC motors are considered ...
