Hall Sensor wiring order

[newmanoid979]

Good Day
I have Hall sensors with Red Black ( center ) Blue wires
Which way round would the wires be connected to a Hall Sensor PCB board looking at it in a clockwise direction

Kind regards


Bill

None of what you say makes any sense. Maybe start again with a bit more detail and some photos.

Good Morning
My fault this may explain better
fig A 0986 is the PCB boards from my original ebike hub
fig B 0984 is a PCB board that i have managed to purchase
fig C 0985 are Hall sensors ang with 3 wires red black and blue
fig E 0987 shows the 2 PCB boards together
As can be seen they are of 2 different sizes the problem being that the Hall sensors of B w to match figill not have the same 0 - 60 -120 degree reach as in fig A

My hope was if i could graft the Hall sensors from fig C onto the PCB boards of fig B
my question are wold i need to change all 3 Sensors to keep them the same and in what order would the red black and blue wires need to be connected
Kind regards

The single sensor is a speed sensor. The board with three sensors is the hall sensor board for motor position. Your motor is a sensorless one. All the sensors work the same. They switch on and off when a magnet goes past, so they're interchangeable.

What is the problem you're trying to solve with those sensors? If your speed is not displaying, you don't need to mess around with the motor. You can use an external wheel sensor.

Good Day
Many thanks for your reply, i am trying to rebuild my original Hongzer 250 watt 36 volt ebike hub but the stalling point seems to be the PCB board, the original one had Hall sensors at 60 degree intervals and is 100mm long and my thoughts were to extent the sensor wire to reach segments at these intervals i am doing this for my own educational purposes i have a new controller Brainpower 120/60 degree angles i come from the pre computer age so ebikes since in i got my first one 2019 have been a very enjoyable learning curve

many thanks

What you're showing and what you're saying don't add up. The pcb that you say is the original one has a single hall sensor, which can only be for speed measurement. You said it had three hall sensors!

If there were three hall sensors in the motor for positional feedback, you can normally see indications of the three positions where they sat in the slots of the stator. All you have to do is put three replacement bipolar hall sensors in there.

Sometimes you need a pull-up or pull-down resistor on the signal wire to ensure that they switch on and off. Good controllers have the resistors on the inputs, but some don't. In the case of the ones that don't, you can either install your own one or get a three hall pcb with resistors on it, but I can see that the one you got doesn't have resistors.

You can test whether you need resistors or not by connecting the halls to your controller, then check whether the signals pulse when you turn the motor backwards. You can only do that test when connected and the controller is powered. If they don't switch and stay 5v, you need pull-down resistors, and if they stay 0v, then you need pull-up resistors around 10K.

Be careful with the hall sensors. They aren’t all the same. Some trigger when they sense a North Pole, some trigger when they sense a South Pole, some are latching and some are non latching.

If you still have all 3 original sensors you can cross check the numbers on them with a data sheet that can usually be found on line to see what type they are and the pin configuration.

On the circuit board black is normally 0v, Red is normally +5v or thereabouts and blue, yellow and green are the hall outputs .

Brainpower controllers are pretty good at figuring all that out.
