Overview
This NXP® reference design of a 3-phase sensorless PMSM vector control drive with a sliding mode observer (SMO) is targeted mainly for compressor control and other consumer and industrial applications. This cost-effective solution uses the NXP MC56F8013 device dedicated for motor control.
- Software written in C-code using some library algorithms
- Available for the MC56F8013 and MC56F8346 digital signal controllers
- Hardware-based on the NXP universal motor control h/w modules
Features
The system is designed to drive a three-phase PM synchronous motor. Application features are:
- 3-phase sensorless PMSM speed vector control (FOC)
- Sliding mode observer with adaptive velocity estimation
- Based on NXP® MC56F8013 (resp. 56F8346) controller
- Running on a 3-phase high voltage (230/115V) power stage
- FreeMASTER software control interface and monitor
