hello all,
My project involves moving a plate mounted over LM guide(linear motion) up and down wards.the motion has to be quite smooth and the whole setup shld be very compact.
so i had stepper motor at first in mind.but to get smooth motion it shld run it in micro stepping mode.and stepper also need huge power supply.
next is simple dc motor.a medium sized motor from printers.which works on 12v@200-500ma.( http://www.pcgadgets.com/DC%20motor.jpg )
now the problem is,i need very low rpm with moderate torque(shld be able to pull plate).this i can do in stepper.but i don't know how using dc motor.
driving the dc motor using PWM will give me good torque(moderate) with low rpm?
I need some desperate help here
Regards
