Re: Torque

Also keep in mind you don't want to design for stall torque. Most things don't like to operate at their limits, case in point the CIM motor... it becomes more a electro->thermal energy conversion device as opposed to an electro->mechanical energy conversion device as its torque output approaches stall.

Remember, this heating is nothing to fool around with: A CIM motor at stall eats approximately 133A... since we run CIMs at 12VDC that would make the motor a 1,596watt space heater... thats a more heat than even your biggest plug-in portable space heaters.

I posted the CIM pdf a little while ago, i'm sure you'll find the torque curves and points of interest charts useful: http://rapidshare.com/files/51500157/CIM.pdf

I also have the big (3") CIM empirical data graphs and tables somewhere....... just have to figure out where I left them

Also, if you are still having trouble understanding torques, I have a physics refrence (ebook) i can direct you to.

Have fun...
