With the same set up as the previous worksheet:
Create a program that runs the DC motor at 50% of its max output power.
Modify the program so that it increases the Dynamometer load from 0% to 100% in 4% steps.
Create routines that measure the torque on the load cell.
Create routines that measure the speed of the motor in Revolutions Per Minute (RPM)
Plot the RPM against torque to a graph. This is a speed-torque curve for the DC motor. Speed torque curves are the most basic way of characterizing electrical machines.
Create additional routines that make plots for speed vs current, and torque vs current.
The system consists of a number of 24V electrical machines, a control unit, software applications for driving the control unit and a set of worksheets.

The Modern Electrical Machines functionality is controlled via a USB COM port connection to the computer. We have provided a library of functions to allow the various aspects of the Electrical Machines system to be investigated and controlled. The various Machines function scripts can be found inside the Primitives folder. The scripts require a global variable to be declared in your project to set the COM port number as shown opposite: The dynamometer rotates in the same direction.
