It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

A knob can make a surprisingly versatile interface, particularly if it’s the SmartKnob, which builds a knob around a BLDC ...

The STM32F103(Bluepill) has been used to achieve this project. It can either be programmed using JTAG or can be done using UART. The pinout of the cheap JTAG connector can be seen here and the pinout ...

Abstract: The encoder and resolver are commonly used rotor angle position sensors for controlling permanent magnet synchronous motors (PMSMs). However, they require significant axial space. This issue ...

Abstract: This paper presents microcontroller based schematic circuit design of a complete duobinary encoder (duobinary code from binary bit) and duobinary decoder (binary from duobinary code) for ...
