Microstepping drive for a stepper motor is a well-known technique to improve the stepper motor performance. Normally, microstepping is carried at fixed pulse width planned. However, this method is ...

Considering the variations of inertia in real applications, an adaptive control scheme for the permanent-magnet synchronous motor speed-regulation system is proposed in this paper. First, a composite ...

For water sports lover Alex Lind, this lack of swell is what inspired him to launch Lind Canvas, a new electric surfboard.
