Since the boom of the NdFeB magnets industry, the usage and potential applications for permanent magnet machines have grown exponentially to the detriment of traditional induction systems. In special ...

The latest in-line shaft generator from ABB is designed to enable ship operators to benefit from the multiple advantages of permanent magnet technology. The new generator brings flexibility and ease ...

There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. I’ve talked with several different application ...

The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...

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 ...

Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

Did you know GM invented the domestic, affordable permanent magnet? Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the ...

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 ...
