Dahlander star-delta starter circuit
Dahlander star-delta starter circuit
(OP)
Haven't used Dahlander motors for many years and even then only small DOL circuits. I'm switching an 18.5/20kW 2/4pole Dahlander wound motor in star-delta and not too sure how to connect it. Any links to circuits would be much appreciated - looked everywhere and can't find any.
I assume you make a delta connection out of the low speed terminals but i'm not sure what to do in high speed.
Needs to be automatic circuit using contactors driven from PLC.
Thanks if you can help..

Depends on constant torque/constant HP/variable torque applications. See

The hardwire star-delta starter schematic is available in manufacturers' catalogs, e.g.
