Instrumentation Laboratory Exercise 29
Laboratory Exercise #3 Test Report NAME:______________________________
Set the power supply to 2 V, 3 V, and 4V. At each voltage, measure the motor voltage, current, and resistance when no load is
applied, and when the motor is stalled (for example, with a heavy load).
Fill out the following table:
V Power Supply
Motor Voltage Motor Current Motor Resistance
No-Load Stalled No-Load Stalled No-Load Stalled
2
3
4
Display the Motor Current as a function of Motor Voltage.
Call the technician and have him verify your setup:
Technician Check
Questions
What is the real resistance of the motor?
Why does it (the real resistance) appear to change with the load?
What is the power supply “droop” (V/A)?
