# Frequent question: What method does not allow braking for DC motor?

Contents

## Which braking method is not possible in DC series motor?

In case of DC Series motor, as the speed of Motor increases, the armature current and hence the field flux will decrease and therefore Back emf E can never be greater than the supply voltage V. Therefore, Regenerative Braking is not possible in DC Series Motor.

## Which of the following is not a type of electrical braking technique used with motors?

Which of the following is not the method of electrical braking? Explanation: Eddy current is the electrical effect or response of the system, which is reflected mechanically at brakes to reduce the speed of the motor. Thus, eddy current is not an electrical brake, it is mechanical one.

## Which braking is not possible in motor?

1. Regenerative braking is not possible in a series motor. Explanation: In regenerative braking, the motor acts as a generator. The back emf is more than the terminal voltage in case of regenerative braking.

## What is DC motor braking?

DC injection braking is a method of braking in which direct current (DC) is applied to the stationary windings of an AC motor after the AC voltage is removed. This is an efficient and effective method of braking most AC motors.

## Can DC motor regenerative braking?

Regenerative Braking in DC Series Motors

Regeneration is possible in DC Series Motor since the field current cannot be made greater than the armature current. Regeneration is required where DC Series Motor is used extensively such as in traction, elevator hoists etc.

## Which is the best braking method?

Explanation: Plugging is the best braking method among all braking techniques. In plugging the value of the armature current reverses and the mechanical energy is extracted. A very high braking torque is produced in case of plugging.

## What are the methods of braking of 3 phase induction motor explain any one method?

Electrical braking has many methods such as plugging, regenerative and dynamic braking. Plugging depends on reversing the direction of the rotating field by changing the supply phase sequence, this results in an opposing torque that stops the motor.
