Answer 1

Question

Chapter 51, Problem 1SQ

To determine

Explain why the three phase braking reduces motor heating when compared with single phase breaking.

Expert Solution & Answer

Explanation of Solution

Discussion:

A DC dynamic brake is a single phase braking used in various induction motors. It requires more current to achieve the braking torque. Therefore, the heat dissipation is more in single phase braking. In a three phase braking, the motor requires less current for the same braking torque, so that the motor heating reduces. Due to the additional winding in a three phase braking motors, the ampere turns are gained.

Conclusion:

Thus, the reason for the reduction of motor heat in three phase braking is explained.
