For which of the following applications is the three-phase induction NOT suitable?

Three-Phase Induction Motors:

• These motors operate based on electromagnetic induction, where the rotating magnetic field in the stator induces a current in the rotor, causing rotation.
• They provide constant speed (synchronous speed minus slip) and high starting torque, making them ideal for loads like conveyor belts, compressors, and pumps.
• A three-phase induction motor is widely used in applications requiring constant speed and high torque, such as conveyor belts, compressors, and pumps.
• Turbines are usually prime movers, not driven loads. However, turbines are generally driven by high-speed steam, gas, or water flow, rather than by electric motors. Instead, turbines are often used to generate electricity rather than being driven by an electric motor.

Applications of Three-Phase Induction Motors:

• Conveyor belts → Require constant-speed operation and good torque control.
• Compressors → Used in HVAC systems, industrial air supply, and refrigeration.
• Pumps → Common in water supply, oil refineries, and chemical industries.
