Why motor has large winding in shunt resistance than armature resistance?
A motor with large windings will have greater shunt resistance than armature resistance due to the sheer amount of copper wire it must travel through. The gauge of the wire also plays a part in this process.
Why use maximum resistance for starting dc shunt motor?
because there is ahigh current flowing through it at the start...
What type of dc motor is suitable for variable torque operation?
A shunt-wound DC motor can maintain its speed well when the load torque varies.
Is 4 point starter used to start and control the speed of dc shunt motor with armature resistance control?
yes
Why shunt resistance is connected in the parallel?
Shunt means parallel only..................
What is DC shunt motor?
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
How will a shunt generator behave if the field resistance is greater than the critical resistance?
the shunt generator wont be started .hehe
How many types of DC motor?
Types of AC MotorsClassification Based On Principle Of Operation:(a) Synchronous Motors.1. Plain2. Super(b) Asynchronous Motors.1. Induction Motors:(a) Squirrel Cage(b) Slip-Ring (external resistance).2. Commutator Motors:(a) Series(b) Compensated(c) Shunt(d) Repulsion(e) Repulsion-start induction(f) Repulsion induction
Why dc shunt generator does not have armature resistance?
It does have armature resistance.
What is critical resistance of the field circuit of a DC generator?
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.
What happen in shunt motor speed if the resistance is increased?
Its performance becomes worse. The speed will drop more when a mechanical load is put on the shaft.
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
