Halls sensor replacement

Post by newbiehere » Oct 08 2018 2:36am

I have a 36 volt 350 watt brushless motor that has suddenly stopped working. I tested the halls supply red/blk and got 6.5 volts but between ground (blk) and yellow blue or green signal wires I got 13.5 volts. One of the halls appears to be facing down, the 2 on the sides up. what would give me such a reading? Is one of the halls open..or since one is facing down, its acting as a voltage doubler? is this normal? I have ordered the honeywell ss41 as replacements.

also, can one change the cap value on the board to a higher rating to put in more voltage, or is it more involved than that?

and..how does one test the phase wires for output? just put the voltmeter lead in one phase wire hole and the other to ground?

That is generally a high voltage as most controllers send 5v to the halls.
but between ground (blk) and yellow blue or green signal wires I got 13.5 volts.
there is usually one return wire, not 3.

We have to take your word for it because the picture is too blurry to see what you are describing.

How do you know your Halls are bad?
also, can one change the cap value on the board to a higher rating to put in more voltage, or is it more involved than that?
You can throw any cap you want into a pc board, but why?

:D

also there isnt usually one return signal wire, there is always 3 on every controller I have seen, otherwise how is the controller going to know which hall is signaling? there is one common 5V supply and blk wire, but 3 signal wires

also, for the signal wires, the pic dont lie. look and observe. 1 red 1 blk 3 signals. for other controllers I dont know but the ones I have all have 3 signal wires.

Still in need of help? I think there's plenty of info on the site or even youtube videos to aid you if you search.

What do you feed the sensor with? 13,5V and 6,5V is higher than the usual logic levels. Either 5V or 12V is common voltages sourced from the controller. What controller is it? Maybe a Kelly?

How to test:
Feed +5V to red and connect black to ground. Measure signal between signal wire and ground. Use a magnet to switch the sensor on/off. Does it switch? If not then it's busted :D

I'd really recommend to get one of these

It' probably the best ebike kit i've bought :D
