Should I maintain any minimum distance between two hall encoders of two motors?
I am a beginner and am trying to build an autonomous mobile robot. I want to use two DC motors with Hall-effect encoders. The image shows the position of the two DC motors.
Do I need to maintain any ...

Can I use a motor as a rotary encoder?
Let me preface this by saying that I'm not an expert, nor do I conclusively understand how op-amps work, but I have a strong suspicion that this should be possible, at least crudely.
I have this idea ...

How to connect an EC11E rotary encoder to a microcontroller?
I'm connecting a EC11E rotary encoder to a Adafruit Feather 32u4 Bluefruit LE. The EC11 has 5 pins: 2 for the switch, and 2 for the knob.
Connecting the encoder itself would be easy, but I'm having a ...

Is it possible that north and south poles of a disc-shaped magnet change position over time?
[See update at the bottom]
We build brushless DC motors of about 1 kW power at 48 volts. In order to drive the motor, we need to know the rotor position and, to do that, we fit a disc-shaped magnet on ...

Minimum Distance between two magnetic rotary encoders in an array : AMS [AS5048B]
I am planning to prototype with multiple AS5048B sensors. (Very basic: Magnets are horizontally placed over the IC that the IC can detect and give an angular reading). I plan to create an array of ...
