Q

A degree of control over the speed of a slip ring induction motor can be obtained by what means?

🔍 Key Concepts

• Slip ring induction motor construction (stator vs rotor circuits) • How speed control is usually achieved in wound-rotor / slip-ring induction motors • Difference between governor control (prime movers) and electrical control (motor windings)

💭 Think About

• Which part of a slip ring induction motor is connected to the external slip rings, and why is that important for speed control? • If you add resistance to a winding, does it affect slip and torque characteristics? Which winding’s resistance is commonly varied for speed control in this motor type? • Which option describes something used on engines or turbines rather than directly on electric motor windings?

✅ Before You Answer

• Identify which circuit (stator or rotor) actually uses slip rings in this motor type. • Eliminate any option that applies mainly to prime movers (diesel engines, turbines) instead of electric motors. • Check which change would realistically control speed and torque without redesigning the entire power system (such as changing the number of phases).
