Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

The quest for energy efficient electric motors has generated a lot of interesting ideas. One of the latest is said to push the efficiency of induction motors to better than super-premium levels by ...

We recently published an article on the Power Electronics with the headline, “Unique Motor Uses Only Permanent Magnets – No Electric Power Required.” We received a firestorm of criticism that this ...

Today, most electric machines operate with radial flux (RF). Magnax offers a new concept, though—a machine that operates with axial flux (AF). Figure 1 provides a comparison of the RF and AF ...
