The most active post in Electrical Engineering Centre blog is Star delta starter and Star Delta motor connection.I received many comments and request for Star Delta circuit diagram.

So this time i want share my simple star delta circuit diagram completed with power and control line circuit.I hope it can be as basic reference for all electrician about star delta starter diagram.

Star delta starter is a common used in domestic and industry sector to drive variant application such as chiller water pump,machinery,air-compressor and many more equipment.

Why star delta become common starter of motor control?

It is because this starter have a simple circuit diagram,low cost application and can drive for high horse power motor with low friction and can reduce starting torque with acceptable condition.

But this starter also tricky for beginner electrician and who not familiar with 6 wire electric motor.Actually it not too difficult if we have fully understanding the principle of star delta motor,starter sequence,circuit diagram and their operation.

For more detail please read my last post about star delta starter,star delta motor connection and many more topics about star delta in motor control categories.

If have any question or suggestion,please drop down your comment and we can share others circuit diagram design.one of my circuit diagram not too clear but i attached together with another circuit diagram for reference.
