Why does a shaded pole motor run at constant speed?
The frequency of the applied voltage is constant.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
What is non-constant speed?
non-constant speed is when the speed for an object does not stay the same
What is the difference between constant speed and speed?
Constant speed is constant velocity which means your going a certain speed in a straight line. Speed is just your speed at an exact moment also called instantaneous speed
What is quasi static process?
Quasi static process is a process in which change in any of the parameters take place at such a slow speed that the values of P,V,T can be taken to be practically constant
Why is the speed of dc shunt motor practically constant under the normal condition?
The speed of dc shunt motor is practically constant under the normal condition because the field flux is constant.
Why speed of the dc shunt motor practically constant under normal load condition?
Because the field flux is constant.
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 is constant speed DC 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 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.
Why do you control the speed of constant speed dc shunt motor?
no it controls your anus
Which type of motor is used for marble cutter?
dc shunt motor. it provides constant speed at all loads.
What is function of dc motor in lift?
Shunt motor is used. For constant speed ,torque will high when load is increased
Why dc shunt motor known as constant speed motor?
A shunt motor isn't literally constant-speed; its speed does fall between no load and full load. If you plot a graph of speed against load, you will find that the speed falls by around 10% or so. Compared with other d.c. motors, this fall is considered to be insignificant -hence the term, 'constant speed'.We apply a similar term to transformers, when we describe them as being 'constant voltage' machines. They're not literally 'constant voltage', but their regulation (difference between full-load and no-load voltage), is considered to be insignificant.
Advantages of dc shunt motor?
it maintains a constant speed under varing load
What is the major advantage of a compound DC generator?
The compound DC motor has the advantage of both, constant speed feature of the shunt motor and the capability to handle high starting torque feature of series motor.
Why speed control of DC shunt motor is necessary?
The total voltage of the batteries or DC power source connected to a shunt motor affects how first it moves. Increasing the DC voltage will make the shunt motor run faster.
