[QUOTE="Hugocz, post: 1135645, member: 415382"] I've also seen EGIS positioned like this on the net. I thought it was an inspiration for you. Again, I don't think it's a good idea. Regulating the motor rotation speed is only part of the solution. The second part is program support. Setting a constant that stops the motor before the desired position is the easiest way. But the accuracy for the elevation depends on the weight of the parabola and its current inclination. I'm thinking of slowing down in steps. According to my experiments, the dependence of speed on PWM is approximately logarithmic. But I still have no idea how complex a program I will be able to design. Functional hardware is a priority. Chokes in the PWM signal path can be a problem. But it depends on the frequency. I believe that in the range of 50HZ to perhaps 500 Hz, the correct value will be found, at which the influence of the chokes will be minimal. [/QUOTE]
