What the factor affect the speed of DC motor?

he factors affecting the speed of a d.c. motor are, 1. The flux Φ 2. The voltage across the armature 3. The applied voltage V


How do you control speed of a motor?

first do you reduce the voltage level or increase the load factor


When speed of fan is increase what is effect on voltage?

voltage would go up typically (you would raise the voltage, not the fan circuit), but it depends on the motor


What are the various method of speed control of 3 phase induction motor?

you can control the speed of a motor by changing frequency, increase or decrease the field winding or by voltage regulation. in these method you can controle the speed of athree phese motor SANDEEP SARKAR


Why variable voltage and variable frequency control is used instead of variable voltage?

variable voltage control has some limitations as you decrease the voltage corresponding phase current will increase lead to increase of flux which lead to saturation of motor core and heating of motor to make flux constant and vary speed of motor v/f ratio need to be maintained constant


Does the speed of induct motor increase or increase when the motor load increase?

Decreases.


Is it possible to reduce speed of shunt motor?

For any dc shunt motor the speed is directly proportional to the armature voltage. hence if you vary the armature voltage by any means( using thyristor ) or static converters using conventional method( ward Leonardo system) surely you can increase or decrease the speed of the shunt motor.

What are the 3 quantities that may be considered as parameters in order to change the speed of a dc motor?

From my understanding of electronics: The input voltage -- generally the higher the voltage, the faster the motor will go. Of course, this will shorten the life of your motor. The motor itself -- Different motors are designed for different applications (i.e. high torque, high speed, etc.) Gearbox (a.k.a. transmission) -- Can increase the speed of a motor with a sacrifice of torque or vice versa.


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 maximum speed DC motor with high voltage?

Depends on the type of motor.


Which the effect of the increase of the armature voltage on the speed of a direct-current separately excited motor in case of constant load?

Increasing the armature voltage would increase the speed. In a separately excited dc motor the speed adjusts so that the back emf generated by the armature is a little less than the supply voltage. The difference, divided by the resistance, gives the current drawn, which is also proportional to the shaft torque supplied to the load.


Why does voltage increase with current with separate excitation?

More current in the field coils means a stronger magnetic field for the armature to rotate in. This causes the output voltage for a generator to increase. For a motor, more magnetic field means that the supply voltage can be matched at a slower armature rotation speed, so the motor runs more slowly but can supply more torque.
