Jerry,
Is the new Gemini 2 going to be happy with lower voltages than the
old Gemini 1?
Anyone know anything about this?
Not an easy question!
We experimented with the PWM handling. The new algorithm gives more
torque at low speeds, so guiding/tracking should be somewhat better.?
Of course, the motors are the same. Once their inductance? and
resistance leeds to increase the PWM duty cycle to 100%, there's a
limit that needs higher voltage to be overcome.
So I think that tracking/guiding performance will be improved at low
voltages, fast slewing higher loads will still need higher voltages.
One member of our beta test made CCD tracking/guiding tests and
achieved very good results.
