on 02026-08-25#Thisismax #video on sensorless #FOC #control of #hardware #motors, using the most hilarious Nerf launcher I’ve ever seen, using three Kv = 2200 drone motors (minimum 10krpm) as rollers to launch the balls in a curved trajectory by controlling their spin. He wanted to use STMicroelectronics’s “#STM32 MC Motor Profiler”, but that would have required using Microsoft Windows, so he used the Arduino #SimpleFOC library instead. He gets motor position feedback from the back EMF of the motor windings (I’m not sure if this is inherent to “FOC”). He says most small drone motors are Y-topology. #electronics
on 02025-11-11#video about controlling #motors with #FOC (field-oriented control) and using them as dials. Using SimpleFOCproject to do PWM microstepping of #brushless motors to get smooth motion down to zero velocity? Also steppers. The BLDCMotor constructor argument is the number of pole pairs, which he got wrong at first. But he’s cheating by using an AS5600 I²C magnetic encoder! This has the very interesting #UX idea of simulating mechanical detents by using the motor for haptic feedback on a knob. #electronics
