    Difference Between Squirrel Cage and Slip Ring Motors ...

    A wound-rotor motor (Slip Ring Motor) is a type of induction motor where the rotor windings are connected through slip rings to external resistances. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Wound-rotor motors can be started with low inrush current, by inserting high resistance into...

    Wound Rotor Induction Machine - HVDC

    The Wound Rotor Induction Machine can be operated in either 'speed control' or 'torque control' modes. Normally, the machine is started in speed control mode with the W input set to rated per-unit speed (say 0.98) and then switched over to torque control after the initial transients of the machine die out (i.e. reaches steady-state).

    4: Wound Rotor and Synchronous Motors - coursera

    Wound-Rotor motors are used in variable speed drive mechanisms, for printing presses, rock crushers and conveyors. Very high starting torque is needed in those machines, higher than you can get in a NEMA type D motor. The graph on the right shows the effect of changing rotor resistance on torque in a Wound-Rotor motor.

    Products – RFL Alternators

    The RFL permanent magnet alternator is more compact and lighter due to the rotor having a fully embedded permanent magnet design, rather than a wound rotor with permanent magnet end. This allows the diameter and length of the rotor to reduce significantly.

    Electric motor - Wikipedia

    In an electric motor, the moving part is the rotor, which turns the shaft to deliver the mechanical power. The rotor usually has conductors laid into it that carry currents, which interact with the magnetic field of the stator to generate the forces that turn the shaft.
