I would like to test the hall effect sensor of a motor (DC brushless Papst dual coil) I have for a small project of mine. I have found a bit of information online, but I cannot seem to figure out what I am doing wrong.
I tried this kind of setup to test it : garagelab.com/profiles/blogs/tutorial-how-to-use-the-hall-effect-sensor-with-arduino
Here is a picture of the motor : http://s11.postimg.org/sqfr6jmar/IMG_20150301_161751.jpg and here is the info that I have with it : http://s18.postimg.org/ra5e6gz61/IMG_20150301_161803.jpg
I am trying to read the output with an an oscilloscope. Here is what I tried : positive battery side to the violet cable, negative battery side to the green cable, positive battery side to 10ohm resistor to my oscilloscope probe and finally the blue (or yellow) cable to the probe.
The only thing I see is a constant 5V from the battery when I manually rotate the motor.
Is something wrong with the hall effect sensor ? With my setup ? With my very basic and limited knowledge of electronics ?
Thanks a lot for you help.
