Dc shunt moter

Ia, flowing through the armature winding of resistance Ra and Ish flowing through the field winding of . In case of self excited DC motor , the field winding is connected either in series or in parallel or partly in series, partly in parallel to the armature winding, and on this basis its further classified as:- Shunt wound DC motor. The DC Shunt-wound motor, running on Direct current, has its field windings placed in parallel to the armature. In Electrical terms, parallel is generally denoted as shunt.

Same voltage is applied to both shunt winding and armature in this motor.

DC shunt motor : Basically motor consists of one rotating and one stationary part.

In series dc motor , the field winding is connected in series with the armature in which high starting torque(high current) is there but with time it decreases.

In shunt dc motor , the field winding is connected in parallel with the armature in whic. It is typically used for industrial, adjustable . Shunt DC motor works on direct current ( DC ). In electrical terminology, a parallel connection is termed shunt. The DC shunt-wound motor is used in applications where load varies and it is necessary for the motor so self regulate speed. A conveyor belt is the classic example, sometimes it is empty, and sometimes it has many heavy boxes.

The series field provides better starting torque and the shunt field provides better speed regulation. However, the series field can cause control problems in variable speed drive . 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. Applications of any motor depend mostly on its speed torque characteristics.

The DC motor will continue its rotation if it is at NO LOAD. The torque-speed characteristic of the motor must be adapted to the type of the load it has to drive, and this requirement has given rise to three basic types of motors: 1. DC motor or compound wound DC motor falls under the category of self- excited DC motors, and it gets its name from the fact that the field winding in this case is connected internally in series to the armature winding. Compound Wound DC Motor or DC Compound Motor. A shunt motor can operate on ac or dc , but the PMDC motor can only w. As we are neglecting the change in the flux ɸ, we can say that torque is proportional to armature current. For the purpose of this article, we will stick with the series- and shunt -wound DC motor.

A shorter air gap can be used because we no longer have to worry about the demagnetizing effect of the armature. A shorter gap means that the shunt field strength can be reduced and hence the . Speed Control of DC Shunt Motor with Field and. Lovely Professional University, PUNJAB, India.

Armature Rheostat Control Simultaneously. Since we have abundant sources of energy . Just like generators, dc motors are shunt wound or series wound or compound wound.
