Part winding connection diagram. Electrical energy can be transferred between the two coils without a metallic connection between the. The star point is at zero potential. 3907 91115 note.
Transformers operate on the principle of induction as shown in below figure. In this type of connection both the three phase primary and secondary windings are connected in delta as shown in the fig. As a result the engine pulls 3 times less power and the main reason why it is used in this connection to start up.

This connection proves to be economical for large low voltage transformers as it. Here a simple spst switch is used to supply power or not to the fan motor and a regulator is used to controlling the fan speed.

A transformer is a static electrical device that transfers electrical energy between two or more circuitsa varying current in one coil of the transformer produces a varying magnetic flux which in turn induces a varying electromotive force across a second coil wound around the same core. When the magnetic field of a conductor that carries a current the primary coil moves across another conductor the secondary coil a voltage is produced in the second conductor by induction.
Three phase asynchronous cage motors can be connected to the network in two ways. This is a simple illustrated circuit diagram of ceiling fanto be noted that the wiring diagram is for ac 220v single phase line with single phase ceiling fan motor.
