Overview
This reference design describes the design of a 3-phase BLDC (Brushless DC) motor drive, which supports the NXP® 56F80X and 56F83XX Digital Signal Controllers (DSCs).
- The speed-closed loop BLDC drive using an encoder sensor is implemented
- The system is targeted for applications in both industrial and appliance fields (e.g. washing machines, compressors, air conditioning units, pumps or simple industrial drives required high reliability and efficiency)
Features
- Voltage control of BLDC motor using Encoder sensor
- Targeted for 56F80X, 56F83XX, and 56F81XX Digital Signal Controllers
- Running on 3-phase Motor Board
Control technique incorporates:
- Voltage BLDC motor control with speed-closed loop
- Current feedback loop
- Both directions of rotation
- Motoring mode
- Minimal speed 500 RPM
- Maximal speed 1000 RPM (limited by power supply)
- Manual interface (Start/Stop switch, Up/Down push button control, LED indication)
- FreeMASTER software control interface (motor start/stop, speed set-up)
- FreeMASTER software monitor
