@nomadradio interesting anyway ...
Well Krap
www.precisionmicrodrives.com
Just shows to go ya that ifn ya use the right search terms ya might get a result.
@nomadradio
All I had to do is search for "Telescopic, five speed vibrating, five speed thrusting, realistic, with seven speeds forward and reverse, remote control DC motor waveform." And there it was!
What can I say? Some days you just get lucky.
Using DC Motor Commutation Spikes To Measure Motor Speed RPM - Precision Microdrives
This explain how to work out the speed of a motor by using its communication spikes and why this is useful when working out a gear ratio

So back to this little gem of a brain bleed waiting to happen .

Solving for I5:5=ℎ(ℎ+1)×2ℎ(+2)+(ℎ+1)2×
So the output voltage is equal to:=5×=ℎ(ℎ+1)××2ℎ(+2)+(ℎ+1)2××
And for no load operation:=ℎℎ+1××
The output voltage between points A and B is independent from power supply and motor current, both with no load and in loaded operation. It is dependent on h, and when increased the output voltage is also increased.
As mentioned previously, the armature resistance will change with temperature – unbalancing the bridge and affecting the output Vrpm. The bridge should be tuned with the motor is at operating temperature to minimize this effect.
This method of speed stabilization was a popular solution for governor rotor speed controllers found in tape recorders using analogue electronics. In the era of the tape recorder, many companies made chips for DC motor control to ensure the tape moved at a constant speed. This was an interesting solution because it operated linearly and didn’t produce any noise, like PWM based controllers.
