Mitsui E&S and Taiyo Electric have developed an Overhang Permanent Magnet Shaft Generating System for large marine ...

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 ...

Permanent Magnet AC motors hold the largest market share because they are more efficient, have a higher torque-to-weight ratio, and perform better in variable speed applications than other motors.

A loop of wire rotating between two permanent magnets generates DC and AC signals. This device can be connected to a DC power supply to run as a motor. Disconnect the DC power supply, if applicable.

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 ...

To meet the demand for drive motors / generators needed for hybrid vehicles, engineers at Remy International Inc. designed a line of off-the-shelf devices that are said to have the highest ...

Opera software for motor and generator design lets users define complex behaviors such as friction, load, and speed-dependent torques. April 24, 2008 Multiphysics capabilities show the effects of ...

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 ...
