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 will happen to a shunt motor if a shunt field coil opens while the motor is running under light load?
Motor will rotate at very high speed leading to destructionAnswer from Kinindia.com
If the speed of the dc shunt motor falls due to loading what will be the effect?
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
What is function of dc motor in lift?
Shunt motor is used. For constant speed ,torque will high when load is increased
Why can we start a shunt motor under no load but why can't a series motor?
The torque on a series motor is determined by the square of the armature current and, so, is very large -much larger than that of a shunt motor. Consequently, on starting, with no back-emf being generated, the torque on a series motor can be dangerously high if the machine has no mechanical load.
Where can you find a diagram for load test of a DC shunt motor?
See the diagram linked below.
Why a DC series motor should never be stared without load?
since torque is proportional to flux and armature current . Flux for dc shunt is constant . torque is proportional to armature current only. And initially armature current is very low hence it cannot be started at load .
DifferEnces of long vs short shunt DC COMPOUND MOTORS?
the basic difference is ,in short shunt motor the series field winding wont carry any current under no load condition whereas in long shunt motors series winding will carry no load current.....
Is swinburnes test direct or indirect test?
in this test their is a no load on dc shunt motor so it is an indirect test
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 there any load in dc shunt motor?
Yes. In order to do work, there has to be a load. In order for there to be current, there has to be a load. Now, that is probably not what you meant to ask. If so, please restate the question correctly.
What is difference between stab shunt dc motor and shunt dc motor?
A series motor respond by decreasing its speed with small increase in current for a given load torque. A shunt motor holds its speed nearly constant with large increase in input current for same amount of load torque
