How Industry Standards Work
- Coils plus sensor to determine what position motor is in - https://youtu.be/bCEiOnuODac
Coreless Motors -
- The Halbach array allows for a coreless configuration as BLDC and BLAC - [1]
Arduino Controllers
- With 3 sensors, including diy? power stage- 3 phase. [2]
- Arduino.just provides the pwm speed signal, rest is off-shelf ESC - [3]
Random DIY
- Taking a fan housing - Hall sensor, 2 transistors, 4 magnets (2 phase) - [4]
Industry Standards
- $50 for 1.5kW - [5]
