  • Generators and Motors Microscope

    It will be revealed how generators and motors use these lines of force to generate electricity, as well as mechanical motion. Magnetic Fields Around Conductors. When a current flows through a conductor, a magnetic field surrounds the conductor. As current flow increases, so does the number of lines of force in the magnetic field (Figure 2).

  • ElectroMagnetic World: AC Motor Construction

    Rotor Construction The rotor is the rotating part of the motor's electromagnetic circuit (Picture 5). The most common type of rotor used in a threephase induction motor is a squirrel cage rotor. The squirrel cage rotor is so called because its construction is reminiscent of the rotating exercise wheels found in .

  • Magnetic Motor Aims to Revolutionize Engine Efficiency ...

    "The power of a motor depends on its speed," said Michael McHenry, materials science and engineering professor. "When you rotate a motor at high speeds, the magnetic material switches at a higher frequency. Most magnetic steels, which is what most motors are made of, lose power at higher frequencies because they heat up.
