  • Induction Generator Nidec Motors

    It is conceivable that the machine could overheat at very low load output. If an Induction Motor is to be used as a generator then this information should be known by the designer so he can make appropriate allowances in the magnetic densities. Induction Motors are usually rated 460 volts for

  • Axial-Flux Motors and Generators Shrink Size, Weight

    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 technologies.. 1. Comparison of radial- and axial-flux machines. Magnax says the key to the high power density is its motors’ yokeless AF design with two rotors at each side of the machine.
