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 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 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 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.
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.
Did Ice T narration for money ball?
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 the effect of feedback on DC servo motor performance?
the sprrd regulation is cnsiderably improved.
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 speed regulation does not apply in dc series motor?
A series motor can run away and reach a high speed on no-load, which happens because it accelerates until the back emf generated in the rotor is nearly equal to the supply voltage. On no-load the current and therefore the field are both small, so the motor speed has to rise to equalise the generated voltage.
