Hello ! Does anyone knows are there a Hall sensors in a Super Soco TC hub motor, and on what pins they are connected to a controller ?

I'm considering installation of engine sound-generator, which needs pulses from hall-sensor in order to extrapolate RPM and provide adequate sound.

The 6 pin connector if you can find it. (It has black +5v, red - 5v, white - I don't know, yellow, green and blue phases.

-5v for black wire and +5v for red of course. Always tripple check when working with your valuable assets.

Thank you very much.

Just to clarify: it should be similar to the Kelly controllers hall input like on the attached picture

 

and I should be able to "steal" hall sensor pulses from one of the hall-A/B/C and GND ?

I use the hall a b and c and steal them to another controller without conneting + or -. 

However in your setup I don't know how many wires you need to connect but if you measure one hall. That hall sensor will give you 0-5v output or if it was 0-1v. Your Super Soco only needs to be turned on and you can rotate the wheel with your hands or throttle. I would start to measure one hall wire. Then I will connect one hall wire to your sound generator.

Again thank you very much for the clarification how hall sensors are wired on TC.

As far as I have understood various documentation on BLDC motors I have read, those 3 hall signals are just phase shifted (probably 120 degrees), but each of them should have same number of pulses for a full rotation of a wheel. For the purpose of connecting sound generator, pulses from one hall sensor are enough. For the particular generator I'm talking about, if voltage for pulse is >= 3.5V then nothing else is needed, but if voltage is 0-1V (which might happen,as you have said) then I'll need to add voltage amplifier between one of the hall sensors and generator (that is where +5V signal can be handy 🙂 ).
