My Content
13 Sep 2008
I am considering replacing a stare delta starter on a centrifugal fan using a 15 HP motor with a soft start. Having looked at quite a bit of information I am failing to understand how you can obtain the required speed and torque using soft start in the star configuration when you will only have 250V across each motor winding.

I can see that the required speed and torque can be obtained in delta mode but this is more complicated and appears to be less populer.
Can any one explain?

Thanks
