🔍 Key Concepts

• Characteristics of a squirrel cage induction motor • How changing the number of poles affects synchronous speed • Which controls are practical for a built-in two-speed design vs. external speed variation

💭 Think About

• For a motor specifically designed as a two-speed unit, which part of its construction can be switched to give two distinct synchronous speeds? • Which of these options would normally require a different power supply rather than an internal motor change? • Does varying voltage or rotor resistance in a squirrel cage design usually create two definite speeds or just change torque/slip slightly?

✅ Before You Answer

• Identify which option directly determines synchronous speed in an induction motor • Recall that a squirrel cage rotor does not normally allow external resistance changes • Distinguish between effects on speed versus effects on torque/current when changing voltage
