This reference design showcases how the NXP® MC56F84789 digital signal controller (DSC) operates two
motors and interleaved PFC in a single MCU.
- Sensorless algorithms eliminate expensive position sensors
- The compressor and fan employ 3-phase Permanent Magnet Synchronous Motors (PMSMs), which provide a quieter,
more efficient, flexible and reliable operation
- Implemented with a back EMF observer, based on NXP Embedded Software Motor Control Libraries and specifically
tailored for air conditioning fans and compressors
- The demo also provides the communication to a Kinetis® K70 MCU touch graphic LCD for added HMI
