Permanent Magnet DC motor characteristics

Drag the dots...

Sorry, this graph requires Java to work.
If you can read this it means that Java is either not available on your machine, or is not enabled.

The powerlock option automatically adjusts the Torque, when the maxmimum Revs are altered, to keep the same Power output.
The input is 24Volts. The examples dont work yet. The default values are as for the Bosch GPA motor.

Note that the output power is determined by the current drawn by the motor.
So if you have a motor, just measure the stall current (you can use 6 or 12Volts to make it easier and extrapolate from there. Also take account of the resistance of your current-measuring device) and you'll be able to calculate how powerful it is:

Adjust the stall current on the graph to the current that you measured.
Adjust the torque so that the efficiency is no greater that 50% at half maximum revs
If you can measure the revs, adjust that too to get an idea of the stall torque.

If the grey box on the right is empty, then try moving one of the graph points,
minimising and then restoring the browser window.
