🔍 Key Concepts

• Relationship between synchronous speed, supply frequency, and motor poles • What "synchronous" means in terms of speed and the rotating magnetic field • Effect of mechanical load on speed of different motor types (induction vs synchronous)

💭 Think About

• Think about the basic formula that links synchronous speed with electrical frequency and the number of poles in the machine. • Ask yourself: does changing the mechanical load normally change the speed of a synchronous motor once it is locked in step? • Compare what happens to speed under changing load for a synchronous motor versus an induction motor.

✅ Before You Answer

• Recall the formula for synchronous speed and identify which variables appear in it (frequency, poles). • Decide whether "pairs of poles" and "line frequency" both appear in that relationship or only one. • Consider whether load affects speed directly or mainly affects torque and power factor for a synchronous motor that is in step.
