Auto Transformer Starter Diagram. The figure below shows the motor with the auto transformer starter. Autotransformer starters are used generally with ac squirrel cage motors having a power rating of more than 20 hp. The winding ab of total turns n1 is considered as primary winding.
We mostly have generator at our homes but the main problem is on/off.
Auto transformer starter, diagram , working explanation. Auto transformer starter is a starter to run th motor.in this starter we use auto transformer,auto transformer has different tap setting. An auto transformer motor starter is a device intended to start ac asynchronous motors, instead of connecting the electric motor directly to the electrical grid, it will connect it to the grid in more than just one step. The auto (greek for self) prefix refers to the single coil acting alone, not to any kind of automatic mechanism. The figure below shows the motor with the auto transformer starter. Wiring diagram of motor starter with auto transformer (4 steps), and the explanation how it work. We mostly have generator at our homes but the main problem is on/off. It is used as an auto starter for induction machines.
