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 the importance of speed control of DC motor in industrial applications?
The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
Why do you control the speed of DC motors?
because dc motor is a powerful & dangerous motor it is akiller
Future scope of dc motor speed control using rf?
The DC motor speed control has a scope of four speeds. The control speeds include; high, medium, low, and off.
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
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?

The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
Can a DC series motor with speed control be connected on AC supply?
A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
What are 2 mathod of speed regulation in DC motor?
The speed of a dc motor can be regulated by the following means:By varying the supply voltage and byUsing a variable rheostat.
What happens to d.c motor when Field is weakened in DC?
when the field winding of dc motor opens the flux is zero so the speed is inversely propotional to speed ,so motor runs at dangerous speed...........
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.
What is maximum speed DC motor with high voltage?
Depends on the type of motor.
What using DC then ac?
It is depends on the application. If we need any variable speed in motor, dc motor will be better choice.
Why do you control the speed of constant speed dc shunt motor?
no it controls your anus
Why do you control the speed of DC motors?
because dc motor is a powerful & dangerous motor it is akiller
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.
