# Which DC motor is a constant speed motor?

Contents

Hence, a DC shunt motor always maintains a constant speed.

## Which motor has a constant speed?

What is the speed of the motor___. A 4 pole, 500V shunt motor has 720 wave connected conductors on its armature.

Q. which of the following motor has the constant speed?
B. shunt motor
C. cumulatively compound motor
D. all of the above

## Is DC shunt motor is constant speed motor?

Detailed Solution. In case of DC shunt motor, flux is practically constant as the field is parallel to the armature. If the load is increased, then the speed of the motor will remain almost constant because the field current remains almost constant. So that it is also known as constant speed motor.

## What is constant speed?

Definition: When the speed of an object remains the same – it does not increase or decrease – we say it is moving at a constant speed. constant speed.

## What is constant in DC shunt motor?

In case of DC shunt motor, the shunt field current is always constant. Since the field winding is connected in parallel to the armature winding and the supply voltage under a constant supply voltage and normal load, then the field flux of the shunt motor remain approximately same.

## Why DC shunt motor is called constant flux or constant speed motor?

DC Shunt Motor Equations

The voltage across both windings remains the same. Thus we put this value of armature current Ia to get general voltage equation of a DC shunt motor. Thus the field flux remains more or less constant, and for this reason, a shunt wound DC motor is called a constant flux motor.

## How do you find constant speed?

Formula for constant-speed = Total distance / Total time taken. Therefore, the constant speed for the whole journey is 62 miles per hour. Example 2 : A person travels from Newyork to Washington at the rate of 45 miles per hour and comes backs to the Newyork at the rate of 55 miles per hour.

## What is another name for constant speed?

What is another word for travel at a constant speed?

cruise coast
stream ride
skate fly
smooth along pass

## What is an example of constant velocity?

We will also explore a special case of constant-velocity motion – that of an object at rest. Three cars are on a straight road. A blue car is traveling west at a constant speed of 20 m/ s; a green car remains at rest as its driver waits for a chance to turn; and a red car has a constant velocity of 10 m/s east.

## Which DC motor is preferred for constant speed application?

Which D.C motor is preferred for machine tools? Explanation: DC shunt motor is a constant speed motor tool machine such as lathe machine requires being run at a constant speed.

## Which motor is used for constant speed and high starting torque?

1. DC Series Motor. Since it has high starting torque and variable speed, it is used for heavy duty applications such as electric locomotives, steel rolling mills, hoists, lifts and cranes.
