from +ve battery to motor terminals:
- A,B,C terminals all same
- all showing constant +1
- the second the probe is removed from one motor terminal, the readout shot up to between 6.5 and 10.5 and then quickly dropped to 1 again.
from -ve battery to motor terminals:
- A,B,C terminals all the same
- readout is 2.84 across all terminals
The above was all done with the multimeter set to 20K ohms.
I wasnt sure if I was supposed to "drive" the motor from the ESC, so did a round of results with same setup as above except Im pushing the throttle on the transmitter.
Results with transmitter throttle:
+ve battery to motor:
1 showing constant, then drops to about -5 then quickly increase to 0 until throttle back (when the meter readout returned to +1)
-ve battery to motor:
1 then 0.54 when touched with probes. When throttling, this increases quckly to +1.
I dont even pretend to understand whats happening, but I do know that we are looking for differences across the terminals - and the results showed that all terminals (A,B & C) reacted virtually identically that I could tell.
Does that help at all?!
