  • High efficiency electrical machine with minimized material content
    Patent number: 5471101
    Abstract: An improved method is provided for the design of high-efficiency electric machines. The maximum practical value of air gap flux density B.sub.g is selected, consistent with maintaining acceptable noise and vibration levels. The value of B.sub.g selected is then used to determine the dimensions of the stator and rotor laminations so as to result in flux density levels that minimize core loss, stator I.sup.2 R and rotor I.sup.2 R losses, and magnetizing current requirements.
