What has to be interchange in order to reverse the direction of rotation of shunt generator?
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
When a shunt generator fails to build up the voltage then how to rectify the fault?
It fails to build up because self excited DC motor's armature have only one direction of rotation. So that if the poles of the armature are reversed, then this causes the reduction in the residual magnetism and eventually, it will stop.
What happens if you short the shunt windings of a motor?
Answer:If the shunt winding is open the motor won't start, but if the shunt open while the motor is running, the motor will keep on running as if nothing went wrong, except if the wire of the winding get maniacally between the stator and the fields the motor can be damaged beyond repair. But normally the shunt windings is done with very thick conductors, so the chance that the shunt will go open is zero.
What are industrial applications of DC shunt motors?
Dc shunt motor is a constant flux and constant speed motor . So that it is used in centrifugal pumps ,machine tools ,blowers and fans etc.
Can a shunt motor be started without residual magnetism?
Yes. The field is provided by the shunt windings, which are connected in parallel with the supply. You may be confusing a motor with a generator, as you cannot start a shunt generatorwithout residual magnetism.
In what two ways can the rotation of a shunt connected dc motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
What has to be interchange in order to reverse the direction of rotation of shunt generator?
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
Theory for load test on dc shunt generator?
load test on dc shunt generator is a test to plot the internal and external characteristics of the generator.
When a shunt generator fails to build up the voltage then how to rectify the fault?
It fails to build up because self excited DC motor's armature have only one direction of rotation. So that if the poles of the armature are reversed, then this causes the reduction in the residual magnetism and eventually, it will stop.
How do you reverse the rotation of shunt motor?
Reverse the armature connections or the field connections, but not both.
Can a dc shunt motor be operated on ac supply?
yes.because the direction of motor is same in both half cycles
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
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.
Which DC motor is constant speed motor?
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
What happens if you short the shunt windings of a motor?
Answer:If the shunt winding is open the motor won't start, but if the shunt open while the motor is running, the motor will keep on running as if nothing went wrong, except if the wire of the winding get maniacally between the stator and the fields the motor can be damaged beyond repair. But normally the shunt windings is done with very thick conductors, so the chance that the shunt will go open is zero.
What is the best type of motor for escalator?
DC Shunt motor
What are applications of dc shunt motor?
applications of series motor
