Hello guys, I am building a system to quickly and efficiently ident. the parameters of a dc motor.
I am applying signals using simulink signal generator that are applied to the motor by the arduino and I read current and velocity data.
Im am using this H-bridge and it works very nice, the motor responds very well to the pwm control ;D
- The motor is brushed 11A peak and 30.2V max
The thing is, Lets say I apply a square wave, full on, full off, 1 sec each.
My question is, should I use fast stop ? or just let the motor by itself slowly reach zero velocity? What mode would give me more precise parameter values ?
Fast stop would make me read a surge current when it goes from full on to full off but it stops as the voltage goes to zero.
Normal mode just letting the motor inputs open won't give me any current readings but I will have velocity values while it slowly stops.
So guys, I tried searching but I didnt find any concrete answer that I could settle with.
What are your opinions ??
