Manual Stator Rocking Analysis

[Yadaraf15]

1) I think it's important to add that at high RPM the required stator movement (or rocking) is very small -- perhaps a fraction of a degree instead of 45 degrees as shown in the video.

2)It would be nice to analyze the rocking further and calculate the degree of rocking required to sustain 450 rotor RPM -- like in Al's video. For example, in this video 45 degrees appears to sustain 1/2 rotation/sec, which is 30 RPM.

Cheer :0

Yada..

For timing of 300RPM we are looking at a 1ms pulse width and a very lightweight actuator. I am thinking that a two stage actuator with solenoid for start up and piezo for high speed is the answer to a test rig as you require. (also just a piezo to maintain and a quick manual spin would work as well). I am mentally creating a AM modulated PWM to drive the solenoid so as the shape the pull distances (similar to a vacuum actuator for cruise control)

I'm taking it slowly and will be collecting data points for amplitude and frequency, and then performing a curvefit and controlling the speed from it.
