Assembly

Circuits for two speeds in the ratio 1 : 2 (winding in the Dahlander pole changing)

Version e.g. for 1500/3000 rpm or 4-/2-pole or 750/1500 rpm or 8-/4-pole

In motors with Dahlander pole changing, the six winding ends 1U, 1V, 1W and 2U, 2V, 2W are connected to the six ter-

minals of the clamping board of a normal motor terminal box.
