:I'm using L297 and Dual H-Bridge MOSFET drivers to drive my Bipolar Stepper motor. The task is to rotate the motor in high RPM. When I am trying to increase the speed of rotation by increasing the clock i/p frequency which fed to L97, Motor makes heavy noise and strucking. but when I'm rotating in lower speed i'm done well.
whats the solution to rotate at high speed. I doubted on quick decaying of the motor current. Is there any possibilities to quick discharge the current. I tried by fly-wheeling diodes and frequency jittering. Advice me anyother mathod. Current rating of the motor is 5A. and Operating voltage is 50 Volt.
Thanks for perfect solution
