5 Reasons Why Your Business Needs Squirrel Cage Rotor Vs Wound Rotor？

Hello OhioAviator,

While I agree with much of what has been discussed here, it is essential to evaluate each application individually, especially if you're aiming to achieve optimal performance with minimal capital investment.

1. High Starting Torque
Wound Rotor Motors excel in generating high starting torque, particularly when used with a properly engineered liquid resistance starter. The torque/speed characteristics are ideal for applications that experience transient overload conditions, and adding a flywheel can enhance performance in shredding applications. However, these motors require more maintenance than Squirrel Cage Motors, which should be a consideration in your decision-making process.

2. Performance of Squirrel Cage Motors
Medium and High Voltage Squirrel Cage Motors are known for their subpar starting performance, often showing Locked Rotor Torque levels below the rated Full Load Torque. As noted by Marke, incorporating a soft starter can further reduce starting torque, potentially leading to operational challenges. Some manufacturers do customize Squirrel Cage Motors, which allows for the possibility of Full Voltage Starting techniques.

3. Variable Speed Control
Wound Rotor Motors offer superior speed control compared to Squirrel Cage Motors. This capability arises from external rotor resistance adjustments and slip rings, which enable operators to fine-tune the motor's speed. This is particularly useful in applications needing multiple operating speeds or precise speed adjustments, such as production lines that process various materials.

4. Maintenance Considerations
Although Wound Rotor Motors provide advantages in torque and speed control, they also demand more maintenance. This aspect should not be overlooked when choosing between these two types of motors. In contrast, Squirrel Cage Motors are typically more robust and encounter fewer maintenance issues, making them suitable for applications with consistent speed demands.

5. Application Suitability
Choosing between Wound Rotor and Squirrel Cage Motors often depends on the specific application requirements. If your application demands high starting torque and variable speed control, opting for a Wound Rotor Motor may be advantageous. Conversely, if your application enjoys consistent speed needs with low maintenance, a Squirrel Cage Motor is likely the better choice.
