Drawbacks of a 3 Point Starter

A 3 point starter has several drawbacks, including its inability to handle large variations in speed by adjustment of the field rheostat․
The starter suffers from a serious limitation when it comes to motors with a wide range of speeds․
To increase the speed of the motor, the field resistance should be adjusted, but the 3 point starter is not designed to handle this adjustment․
This limitation makes the 3 point starter less versatile and less suitable for applications where speed adjustment is necessary․
The starter’s design also makes it more prone to wear and tear, as the contacts are subject to high stress and may fail over time․
Additionally, the 3 point starter may not provide the smoothest start, as the resistance is not gradually reduced, which can cause current surges and damage to the motor․
Overall, the 3 point starter has several drawbacks that make it less desirable for certain applications, and other types of starters may be more suitable․
The limitations of the 3 point starter should be carefully considered when selecting a starter for a particular application․
