I am using a Bipolar Motor Rated at 4.5V 1.2Amperes and coil resistance at 3.8Ohms at a standard step angle of 1.8 degree.
I wish to overdrive the motors at 9.6V using L297 - L298 Driver Circuit.
The circuit provided by L297/L298 data sheet as a reference I want to design the motor driver circuit. In this circuit the Sense Pins ( given in Datasheet as 0.5Ohms at 2W ) controls the current during overdriving.
Can anyone tell me if for 9.6V what should be the value of sense pins ?
Also please tell me everything regarding overdriving as well , also the hazardous in not giving a proper chopping circuit !
