Motors & Stater Selection Summerized

8 First, always consider the simplest and most reliable combination - standard squirrel cage motor with DOL starter. If this cannot be used because of starting current limitations, then consideration should be given to a star/delta or auto transformer starter.

8 If a very high starting torque is required a larger motor can be used but this will of course increase the starting current.

8 Solid state starters should only be considered if both current limitation and reasonable torque is required. However the cost is very high compared to both star/delta and auto-transformer starters.
