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 ...

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 ...

If the running current of a PKP Series stepper motor is decreased and the motor is operated at the same torque as the PK Series standard type, current consumption and heat output can be reduced.

Final thoughts Permanent magnet AC motors are not exactly novel technology, but they are still in the minority compared to more old-fashioned motors. There’s a lot of capital cost and work that needs ...

Permanent magnet motors are quickly becoming popular in various industrial and commercial applications. Not only are they more efficient, but they are also longer lasting and require less maintenance.

On each of the poles of the permanent magnet, there is a toothed structure – Front toothed cup and rear toothed cup – separated from each other and angularly offset by half a pitch of teeth. The ...
