BMW’s Rotor Secures Magnets Under High RPM Stress Being a central part of the motor core, rotor design is critical to motor performance and efficiency. Because electric motors can spin at up to ...

A new method for determination of the steady-state equivalent circuit parameters of wound-rotor induction motors using experimental data from starting transient measurements is presented. The ...

Unlike squirrel cage motors that have a fixed rotor resistance, slip ring motors feature wound rotors connected to the external circuit through slip rings. This design allows for the adjustment of the ...

Motors that employ SESM tend to be larger and require a direct current to turn the rotor. This DC is often supplied by slip rings or an AC induction with a rectifier.

The latest motor architectures assist in curtailing or eliminating the economic, environmental, and geopolitical costs associated with the rare-earth materials used in most electric motors. Why EV ...
