This is certainly a 2 phase brushless motor.
Thanks for the feedback. How about the power requirements? Is there an easy (cheap) way to generate the sinusoidal excitation?
Two phase Permanent Magnet Brushless DC (PM BLDC). The motor has six poles and uses resolver commutation. The resolver requires an excitation voltage of 4.0 Vrms at 20 kHz, transformation ratio is 0.5
The current is about 2 amps, 28 VDC. The motor will be operating at about 10,000 rpm
I am...
Why? It is very powerful for its size, and it can withstand extreme environments. 3-phase may be possible in the future, but for now I'm stuck. Yes, this motor is rare - it is custom engineered, and very expensive.
Trouble is, I don't have much DC motor experience, and I'm having trouble just...
Does anyone know a good source of info on 2-phase 6 pole perm magnet servo control? I'm using resolver feedback.
All web and book info I can find is 3 phase, which I can't use in my application.
