Problems
I have Nema23 stepper motors for 3 amps high torque 425oz-in.
Before I've made PMinMo drivers L297-8 for 2Amps and they work.
Connect them and I have extreme heat from the L298...Maybe that is normal, I know they need cooling but is there any other problem with the motors connected to this drivers. Can I run the motors with good cooler mounted on L298 without other problems?
I want to make more drivers with higher current... more than 5amps...6amps or higher
Can you help me with some tested schemes for driver board for high amps and voltages, and can I somehow connect 2 drivers like parallel connection every wire for controlling signals, for power supply for motors etc etc and connect only one motor and get for same signals more current.. like 4 amps from 2x2amps, maybe I said some stupid things here but I don't understand how it works in detail. sry...
once again I need tested schemes for high current and volts bipolar stepper drivers, thanks
