Abstract: A rotor for a high-speed, high-power electric motor includes, according to the rotor axis, a magnetic mass surrounded on both sides by short-circuit rings, and crossed at several notches by electrical conductors connecting the short-circuit rings to form a squirrel cage. Each electrical conductor is formed of a single bar having a trapezoidal section over its entire length.
