But you can have different torques at same size of the motor. They increase the size of the motor in length. so you will be still able to alter torque to some extent no matter speed. Keep in mind that you are flexible here up to certain point. After that, if you need more torque you go to next bigger size of motor nema 23 or so.

My guess is that what you have on market is pretty much optimized per cost/performance but you may well be more efficient for your particular case. > l. > > _______________________________________________ > arm-netbook mailing list [email protected] > http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook > Send large attachments to [email protected] > -- Hrvoje Lasić Vulpes d.o.o.
