Salient Pole Rotor Vs. Non-Salient Pole Rotor
Here is the difference between the Salient Pole Rotor and the Non-Salient Pole Rotor as mentioned below.
| Aspects | Salient Pole Rotor | Non-Salient Pole Rotor |
|---|---|---|
| Design and Structure | Poles project outward; large diameter, short axial length; laminated steel poles | Smooth cylindrical shape; uniform winding; solid steel construction |
| Speed Suitability | Low to medium speeds (below 1500 RPM) | High speeds (above 1500 RPM) |
| Applications | Hydroelectric generators, low-speed applications | Steam and gas turbines, high-speed applications |
| Torque Generation | High torque at low speeds | Less efficient torque generation at low speeds |
| Efficiency | More efficient at low speeds | More efficient at high speeds |
| Windage Losses and Noise | Higher due to irregular shape of poles | Lower due to smooth cylindrical shape |
| Mechanical Strength | Lower, not suitable for very high speeds | Higher, suitable for high-speed operations |
| Cooling | More efficient due to large surface area | Less efficient compared to salient pole rotors |
| Manufacturing Complexity | Simpler and cost-effective | More complex and costly |
Salient Pole Rotor Vs Non-Salient Pole Rotor
A rotor is a rotating part of a motor or a machine. This part consists of a multi-pole electromagnet which produces the electrical power. There are two different types of rotors i.e. Salient Pole Rotor and Non-Salient Pole Rotor. Salient Pole Rotor is a type of rotor which have multiple salient poles and they all are located on a mounted wheel.
On the other side, a Non-Salient Pole Rotor is a cylindrical rotor that is small in diameter and has a long axial length. In this article, we are going to discuss the differences between the Salient Pole Rotor and Non-Salient Pole Rotor in detail.
