Slip ring induction motors offer several advantages, including:
1. **High Starting Torque**: They provide high starting torque compared to squirrel cage motors, making them suitable for applications with heavy starting loads.
2. **Speed Control**: They allow better control of speed through external resistance in the rotor circuit, which is useful for processes requiring variable speeds.
3. **Reduced Starting Current**: By adjusting the external resistance, slip ring motors can limit the inrush current during startup, reducing stress on the electrical supply and associated equipment.
4. **Improved Performance**: They can handle overload conditions better and offer smoother performance under varying loads.
