🔍 Key Concepts

• Shaded pole motor construction – look for copper shading coils on part of the stator pole face • Square core, open-frame design typically used for very small fan or instrument drives • Non‑reversible characteristic – shading coil creates a built‑in preferred direction of rotation

💭 Think About

• On which pictured motor can you clearly see a small copper loop or band around part of the pole piece instead of a separate start winding or capacitor? • Which motor has an exposed, roughly square laminated iron core with a simple coil and no external reversing features like extra leads or a capacitor? • Which design looks like it would be used for tiny fans/timers rather than higher‑power machinery?

✅ Before You Answer

• Verify which option shows copper shading coils on only a portion of the stator pole face • Confirm the motor you choose has a simple, single‑winding construction without a start capacitor or centrifugal switch • Make sure the frame/lamination stack is roughly square in shape and appears suited for very small load applications
