Synopsis
Learn a precise way to measure dynamo and motor efficiency with paired machines.
This guide explains Hopkinson’s method, where two identical dynamos work together on one bedplate to improve accuracy beyond ordinary tests.
The text walks you through setting up the experiment, wiring the machines, and using meters to capture armature and field currents, as well as voltages at the brushes and terminals. It shows how to balance the two machines, regulate speed and excitation, and read results that reveal the efficiency of each unit under different loads. Practical notes cover using a Crompton potentiometer to speed and simplify measurements.- How to connect a dynamo and a motor in a single circuit for high-precision tests.
- Which currents and voltages to monitor and how they relate to efficiency calculations.
- Steps to adjust speed and field strength for accurate, repeatable readings.
- How to use a potentiometer to streamline multiple readings for each load.
