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.

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 ...

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 ...

Figure 8 depicts an electrical vehicle climbing an incline moving forward (top) or in reverse (bottom). When the vehicle rolls downhill it will turn the motor pressed by the force of gravity so the ...

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 ...

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...

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 ...
