Wound-Rotor Induction Motor
A type of induction motor where the rotor has windings connected to slip rings, enabling variable resistance to be inserted in the rotor circuit for speed control.
Starting Torque
The initial torque produced by a motor or engine upon starting, critical for overcoming inertia and commencing rotation.
Starting Current
The initial surge of current experienced when an electric motor starts, typically much higher than the running or nominal current.
