Auto Transformer Starter
The starting current is limited by (using a three phase auto transformer) reduce the initial stator applied voltage. The auto transformer starter is more expensive, more complicated in operation and bulkier in construction when compared with the star – delta starter method.
Simply so, what are different types of starters?
Based on the above techniques, the most common types of starters are listed below.
- Stator resistance starter.
- Auto transformer starter.
- Star-delta starter.
- Direct on-line starter.
- Soft Starter.
Also know, what is starting method of induction motor?
Starting methods of Induction motor include: Direct –On– line (DOL) starters for less than 10 Kw motors. Star–Delta starters for large motors. The stator winding is initially connected in a star configuration and later on changed over to a Delta connection, when the motor reaches rated speed.
The three phase induction motor may be started by connecting the motor directly to the full voltage of the supply. The motor can also be started by applying a reduced voltage to the motor when the motor is started. The torque of the induction motor is proportional to the square of the applied voltage.
