A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator. It consists of a coil of wire through which a current flows.Click to see full answer. Also to know is, what is the function of bearing in DC generator?The ball or roller bearings are fitted in the end housings. The function of the bearings is to reduce friction between the rotating and stationary parts of the machine. Mostly high carbon steel is used for the construction of bearings as it is very hard material.Also, why is a commutator and brush arrangement necessary for the operation of a DC generator? Commutator and Brushes on DC Motor. To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point. Subsequently, question is, what is the purpose of field windings in a generator? Field winding is used in alternators and synchronous motors. The purpose of the field winding is to create a rotating magnetic field inside the equipment. In alternator the rotation will be initiated from outside and for the synchronous motor it will be from inside.What are the main parts of a DC motor? The basic parts for DC motors are as follows: Stator. The stator carries the field winding and Poles. Rotor. It carries the armature winding. Armature Winding. Field Winding. Commutator. Brushes. Poles. Slot/Teeth.
