Overview
This reference design is for a sensorless permanent magnet (PM) motor drive single-chip solution based on the NXP® DSC56F80XX digital signal controller (DSC).
- An electronically controlled three phase PM motor provides a unique feature set with the higher efficiency and power density
- This application presents a motor control technique of PM motor without a need to use a rotor position transducer
- This technique particularly targets horizontal axis (H-axis) washing machine with belt drive in fractional horsepower range
- A designer reference manual provides a detailed description of the application, including the design of the hardware and the software
