ABSTRACT:
In a brushless D. C. motor which is controlled by electronic circuits, the armature which is of the shorted drum type, is constructed in the form of a double or multiple coil winding which acts to prevent high circuit interruption potential which might damage the electronic control circuits. The double or multiple winding may be constructed as a double or multiple conductor winding. The multiple windings are separate one from the other and are connected together to supply terminals through the electronic control circuits.
