Well after a couple blown PWM modules, a burned relay board I figured time to fix the azimuth drive properly
So far the main motor been an old rv slide out unit, 10 RPM at 840 inch pounds, this then went to a 2 to 1 further reduction, so 5 RPM
(5rpm / 60) * 360 = 30 degrees per second, needles to say horribly fast, stresses the frame and the motor.
So I finally got a 40:1 worm drive. So made a simple shaft coupler system and ruffing out an adapter plate.
Had to take the motor apart and clean it up.

So this will end up with 10rpm / 42 = (0.24rpm / 60) * 360 = 1.44 Degrees per second way way better!
So sun moves 7.5 degrees per 30m (I have it set to adjust every 30m to save wear on the motor) means now unit will run for 5.21 seconds, means much better wear pattern on the brushes and happier motor rather then massive 1 second surges!
Ideally now my psu and drive motor will be much longer lived and no more weird burn outs!
Next stage is to fabricate an adapter plate to mount on the bell housing, this will be 6" by 7" by 1/4" aluminium. will post an update once that is made and some picks of it when mounted back to the array and see if this will let me post a video of it in action.
