Working of dc shunt motor

In Electrical terms, parallel is generally denoted as shunt. Same voltage is applied to both shunt winding and armature in this motor. A conveyor belt is the classic example, sometimes it is empty, and sometimes it has many heavy boxes.

The DC shunt motor can keep the boxes moving by increasing torque. Because of which it finds wide spread industrial application where ever constant speed operation is required.

In DC Shunt motor the field winding is connected in parallel to the armature winding , so the field current is constant, because supply voltage is fixed.

In conventional dc machine field winding is mounted on stator and the armature winding is on.

The production of electrical energy, and its conversion to mechanical energy in electric motors of all types, is the basis of our industrial structure. At this point, field winding of the shunt or the compound . The most common types rely on the forces produced by magnetic fields. DC series motor works on the direct current converting electrical energy to mechanical energy. The interaction of the generated magnetic field and external magnetic field in the . DC motor principles are found elsewhere on this site.

Industrial Electronics, Second Edition, Prentice Hall PTR. The Ea is related to armature speed andmain field flux by: Ea = k1nφ (1). This video will help you to understand about construction of Shunt wound DC Motors , Its principles and controlling details of direct current shunt wound moto. What an amazing explanation and animation. One problem, the comutator is the wrong way, the tall side should be against the armarure so the windings are pressed and soldered into, the long and narrow part on the com . They work well at variable speeds and have great torque.

Direct current motors were the first kind of electric motor. Debaprasad Kastha, Department of Electrical Engineering, IIT Kharagpur. Reverse operation is again achieved by reversing the field current supply as shown in Figure.

Before variable-voltage supplies became readily available, most d. So, working at the same current density, the cross section of each turn of the series field winding needs to be times that of the shunt field wires, but conversely only . The armature and field winding are connected in parallel.
