WebShunt wound dc machines – Here, field winding is connected in parallel with the armature winding. Hence, the full voltage is applied across the field winding. Shunt winding is made with a large number of turns and the resistance is kept very high (about 100 Ohm). It takes only small current which is less than 5% of the rated armature current. WebSome DC machines are constructed with a permanent magnet (PM) field, which results in a constant flux. In a PM DC machine, the armature circuit model is the complete circuit model. We will consider three types of wound field DC machine. In a wound field machine, the flux is produced by a field winding. The machine types we will consider are:
