BLDC driver
Contents
Description
This is a CPU BLDC motor controller, based on NXP application-note AN10898.
The difference with dedicated BLDC motor-control IC's is that functionality can be modified and integrated with other Software modules:
- PID
- Quadrature-Encoder
- Position-Control
LPC1700 is an advantage due to experience with LPC1700 based projects
Using discrete-parts and not IC's for the power-driver gives flexibility for changes and purchasing
Status
*AN10898 software-project already build with Keil free version uVision tool-chain. *All NXP discrete parts for AN10661(LPC2141) already purchased. (Same parts for AN10898-LPC1700)
