Chapter 21, Problem 1RQ

To determine

The full load running current of DC motor.

Explanation of Solution

Given:

The power of the motor $\left(P\right)$ is $20\text{hp}$.

The voltage applied to the motor $\left(V\right)$ is $500\text{V}$.

Calculation:

Refer to the Table $430\cdot 247$ “Full load current in Amperes, Direct Current Motors.”

The full load running current of DC motor with a power of $20\text{hp}$ at a supply of $500\text{V}$ is $\underset{\_}{34\text{A}}$.
