I and my friends tested our Fisher and Paykel motor with the following specifications:
60S stator wired in parallel (60P)
42 slots, 28 pole pairs
Star connection
Current Rating is 20A
Hall Sensors are from F&P Smart Drive
Magnets with steel liner fitted in an Aluminum enclosure instead of plastic from factory setting
Operated with 12 FET Lyen Controller with 5k pot as throttle
I was wondering why most of the combinations from the 36 demonstrated an oscillation like this. Also, we tested our sensors with this schematic as posted by fechter here. However, as we rotate the rotor, only two sensors were active and the other one does not light up the corresponding LED. On top of it, during rotation, the two sensors continuously lit up and no blinking was present. Could sensors be the main issue here? Should we connect the common point of star connection to ground?
