Question
Chapter 57, Problem 1SQ
To determine
Explain about the base speed of a DC motor.
Expert Solution & Answer
Explanation of Solution
Discussion:
The base speed of a DC motor is the speed attained by a motor at rated armature voltage, rated load current, and rate field current.
The motor operates below base speed when the armature voltage is reduced. The torque of the shunt motor remains constant at below base speed. The motor operates above base speed when the field current is reduced.
Conclusion:
Thus, the base speed of a DC motor is explained.
