Hai evryone.
I have a sanyo-denki 5.1v,1A,2kg-cm six wired stepper taken from an old
dot matrix printer. Two wires are the center taps.
I am using the unipolar configuration.
We are using a "MINI 51" Evaluation Board Which consist of an Philips
p89c668h micro controller of 8051 architecture for generating
the signals for the stepper.
Now The problem is The driving ckt. I made one with 2803.
but the torque is low and the IC overheats quickly.
The power supply indicated the current drawing is 700mA.
Can i use TIP122 darlingtons for the job?
Can i directly connect the TIP122 s with the microcontroller?
I read somewhere that for increasing torque and speed we have to increase the supply voltage. Is it fine?
Did it burns my motor?
Also what is the procedure ? just increase the voltage?
Plese help me.....
(I am a mech engg student.So please describe more)
Thanks in advance....
