This eliminates the secondary circuit rotor I2R (heat) losses found in the induction-motor design, resulting in higher efficiency and a better power factor to boot. Rating for rating, PM-rotor ...

The two most important electric motors are the ac induction motor and ... types of motors have different rotor configurations and operate very differently. Design tools like CD-Adapco’s SPEED ...

more efficient motor design free from rare earths in 2021. The German automotive supplier has been using wireless induction with a rotor configuration it calls the Magnet-free Contactless ...

Copper cuts down on the I2R losses by up to 40% and overall motor loss by 20%, though it increases the weight of the rotor a bit. The motivation for a copper-rotor design stems not only from ...
