    Using a brushed DC motor as a mechanical (variable) load...

    I tried on my bench two small 12v motors with the shaft connected - and it worked fine!! One motor had the P/S (CH1) at 12V, the second was run in constant current mode (CH2), by varying the current in the second motor the speed (of the common shaft) slowed down. I guess this is obvious really...

    Using a brushed DC motor as a mechanical (variable) load...

    Basically I'm interested in the pros/cons/implications of using a DC motor as a mechanical load... if anyone has experience in this area? One option is a passive approach, which would be to just apply a resistor across the terminals to load the motor when it starts to spin (driven by an...
