Overview
This reference design describes the design of a 3-phase sensorless brushless DC (BLDC) motor control with back-EMF (electromotive force) zero-crossing sensing using an AD converter for the NXP® 56F80X and 56F83XX Digital Signal Controller (DSCs) dedicated for motor control applications.
- It can also be adapted to Our 56F81XX Digital Signal Controllers
- The system is designed as a motor drive for three-phase BLDC motors and is targeted for applications in both industrial and appliance fields (e.g. compressors, air conditioning units, pumps or simple industrial drives)
- The reference design incorporates both hardware and software parts of the system including hardware schematic
Features
- BLDC sensorless motor
- 115 or 230V AC Supply
- Targeted for 56F80x, 56F83XX, and 56F81XX Digital Signal Controllers
