Motor encoder alignment

[danSN]

Hi,

What is the best way to realign the encoder with a brushless motor.?
I had a good brushless with a bad encoder.
I allready install a new encoder but at hi pps the motor just stops (error from the Rutex drive)

Thanks

Dan

If your encoder has three simulated 'Hall' tracks, I have done it with a double beam scope, as follows.
Connect a 10k ¼w resistor to each phase and connect the other three ends together to make a star point. This is you scope common for the first channel and the input lead to the U phase.
the other 'scope channel is for the hall effect output for the U pulse.
Rotate the motor either by hand or by some low speed means and a generated sine wave should be observed on the U phase out. The square hall effect pulse should be then aligned with the the centre of the sinewave output.
The other Hall pulses can be verified the same way with the corresponding motor phase.

Al,

Thanks for that info. I wouldn't have been able to answer that, but it seems logical.

By the way, the R2030 drives are enroute from Australia. I believe I will have them in just a couple of days from now!

Al: any way you can make a drawing of the layout you describe???

I'm dyslexic when it comes to 'word problems'. Heck , can't even read a vernier micrometer nor a slide rule. If it hadn't been for TI calculators, would never have gotten thru college.

Here is the method, power is to Encoder ONLY. Waveform diag. shows all three waveforms at once.
