We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rot… ...

If you treat the pins as binary, you can read them as 00, 01, 10, or 11 (sequence the encoder outputs while spinning clockwise is 00, 01, 11, 10). If you have a reading of 01, the next reading can ...

By stacking some small PCBs behind the motor body, it was possible to squeeze a DRV8837 DC motor driver and a pair of hall effect sensors on the first PCB layer, with the magnetic encoder nestled ...
