hi every1, i am using stepper motor for my cnc machine...its model no is em284 stp-42d221-01 by shinani kenshi......i dont know any specs of this motor neither voltage rating nor current rating even i dont know its RPM.i am usig IRF640 mosfets to drive stepper motor along with 817b optocoupler.
i am running my stepper motor at 12 V.i have to do diagonal motion so i am running two stepper motor simultaneously.
Problem is when i use 12 V power supply with 4.2 A current rating my motors are getting heatup and also driver circuit is also getting heat up....bt the motors are running smoothly and are not missing the steps.
and when i use 12 v supply with 2 A current rating both motors are missing the steps but this time both driver and motor are not getting hot.
I dont know where is the problem????what should i do??? either there is a problem in my driving voltage or problem in driving current or is there any other issue???
the driver circuit for both motors are in parallel that means if i use 2A source then 1A current is going in each driver means in motor.
Please help me out!!!!!
