Question
Chapter 47, Problem 1RQ
To determine
The full load running current of the 20 horse power motor as it is connected to 500 V DC line.
Expert Solution & Answer
Explanation of Solution
Consider the table shown in 430.247 in the textbook. The table shows the full load current values for the dc motor at the base speed for the different voltages and the horsepower values.
Therefore, the full load running at 20 HP DC motor connected to 500 V DC line is 34 amperes.

The design must ensure efficient power transmission, reliability, and safety. Given the following specifications and constraints, design drive system for this application: Specifications: Motor Power: The electric motor provides 10 kW of power at 1,500 RPM. Output Speed: The output shaft should rotate at 150 rpm. Design Decisions: Transmission ratio: Determine the necessary drive ratio for the system. Shaft Diameter: Design the shafts for both the motor and the conveyor end. Material Selection: Choose appropriate materials for the gears, shafts. Bearings: Select suitable rolling element bearings. Constraints: Space Limitation: The available space for the gear drive system is limited to a 1-meter-long section.
