| 2. It is a constant Flux device. | 2. It is a variable flux device. |
| 3. It is a constant frequency device. | 3. It is a variable frequency device i.e., stator frequency=50HZ, Rotor frequency=s.f |
| 4. It can operate at any power factor (lag,lead,upf) | 4. It can operate at lagging power factor (only lag) |
| 5. It has continuous magnetic circuit. | 5. It has discontinuous magnetic circuit. (due to air gap) |
| 6. It is a electromagnetic Energy conversion device. | 6. It is a electromechanical Energy conversion device. |
| 7.Magnetising Current Iμ = 4% to 5% of IFL | 7.Magnetising Current Iμ = 25% to 35% of IFL |
| 8.Efficiency of Transformer is high. (90% to 95%) |
8.Efficiency of Induction Motor is low. (70% to 88%) |
