Encoder or hall sensor for X-NUCLEO-IHM16M1(STM32 P-NUCLEO-IHM03 pack) ?

[cadena]

Hi everyone,


I am interested in buying a P-NUCLEO-IHM03 motor control pack but I would need to find, preferably, encoder or, at least, Hall sensors I can use with the  X-NUCLEO-IHM16M1 and test the rotary speed of the motor. Could someone please recommend me sensors that work fine with this board ? Thanks in advance.

Many motors include built in encoders. Connecting an encoder adds to the length of the shaft and requires accurate fitting. If you do not have the option of purchasing a motor with a built in encoder then I would go for the Hall sensor. I have used them many time to great effect and they are very cheap. Keep in mind that:

a) Hall sensors only sense ferrous (e.g. steel) targets, they will not sense aluminum

b) To sense a ferrous but non-magnetic target the hall sensor must include a built in magnet. Many hall sensors, include all of the hall effect 'electronic chips' will only measure a magnetic target.
