I have a bipolar stepper motor with 3 ohm winding resistance, ~4kg weight and 160mm x 87mm dimension. I have not any other informations about this motor. I want to build driver using L297 & L298.
I want to find following things according to above stepper motor:
The value of sense resistors
The value of variable-resistor in L297's chopper
The recommended stepper power supply (L298 - pin 4)
The schematic of L297's chopper attached. Is it suitable? You may recommend adding other component in this schematic.
Edit: I have uploaded another schematic for limiting reference voltage for L297. Please suggest which one is more suitable.
Please recommend above three things.
Thanks in advance
