Abstract: Model predictive control with duty-cycle optimization has been widely adopted for induction motor drives. However, a fixed combination of a null vector and an active vector fails to ...

With extra-large wheels, a long hose, a high-end induction motor, and a well-designed GFCI plug, this Ryobi model is the most user-friendly electric pressure washer. This DeWalt model is similar ...

giving the rotor a little boost. The difference here is that rather than low-friction sapphire bearings, this motor uses zero-friction magnetic levitation using pyrolyzed graphite discs.
