Shunt motor characteristics
Web2 days ago · The field winding in shunt DC motors is made of many windings of thin wire, to both increase the magnetic field’s strength and limit the current through the coil. By doing so, the current is reduced through the field coil and thus increases in the armature (remember, the current is shared when in parallel). The larger current in the armature ... WebThe field winding of DC shunt motor is wound with many turns to increase the flux linkage and the armature winding is designed to carry higher current. This is done because the …
