Article 445 contains the electrical installation and other requirements for generators, including such things as where generators can be installed, nameplate markings ...

Sizing conductors and protection for rotating electrical equipment is commonly required in the field and on exams. The rules are separate for different types of equipment and can become quite involved ...

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 ...

Plug-in electric vehicles for passengers continue to become more mainstream within the automotive market, and the shift in that direction shows no signs of slowing down. In fact, Bloomberg New Energy ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

Given the array of ratings and standards in the marketplace, selecting a generator set can be confusing. But, by aligning your requirements with the proper generator set ratings, you can ensure your ...

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 ...

A crucial factor to consider when planning maintenance of high-voltage (HV) motors and generators, especially those in critical industrial applications, is the life expectancy of the stator windings.

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 ...
