Starter for 20 HP Squirrel Cage Induction Motor
The recommended starter for a 20 HP squirrel cage induction motor is the auto transformer starter. The following points explain why:
What is an Auto Transformer Starter?
An auto transformer starter is a type of starter that uses a single winding auto transformer to reduce the voltage applied to the motor during starting. This type of starter is commonly used for squirrel cage induction motors.
Advantages of Auto Transformer Starter
The advantages of using an auto transformer starter for a 20 HP squirrel cage induction motor are:
1. Reduced Starting Current
The auto transformer starter reduces the starting current of the motor, which is important for preventing damage to the motor and reducing the stress on the electrical system.
2. Smooth Starting
The auto transformer starter provides a smooth starting current to the motor, which is important for preventing the motor from jerking or stalling during starting.
3. Cost Effective
The auto transformer starter is a cost-effective solution for starting a 20 HP squirrel cage induction motor, as it does not require expensive components or complex wiring.
4. Easy to Install
The auto transformer starter is easy to install and maintain, which makes it a popular choice for small to medium-sized motors.
Conclusion
In conclusion, the auto transformer starter is the recommended starter for a 20 HP squirrel cage induction motor due to its reduced starting current, smooth starting, cost-effectiveness, and ease of installation.

The starter recommended for a 20 hp squirrel cage induction motor is:a...
The direct on line (DOL) starter method of an induction motor is simple and economical. In this method, the starter is connected directly to supply voltage. By this method, small motors up to 5 HP rating are started to avoid the supply voltage fluctuation.
The star-delta starter method of starting three-phase induction motors is very common and widely used among all the methods. In this method, the motor runs at delta connected stator windings. It is also used for motors of 5-15 HP rating.
The Autotransformer is used in both the type of the connections, i.e., either star connected or delta connected. The autotransformer is used to limit the starting current of the induction motor. This method is used for the high rating of squirrel cage induction motors. So, this method is most suitable for motors having ratings of more than 15 HP.
