Sinusoidal control of BLDCM with hall sensors

This application note discusses the design of a 3-phase BLDC motor drive with Hall sensor based on sinusoidal waveform and Freescale's FRDM-KE04Z. This application design takes the advantages of KE04Z peripherals for motor control.

The application is a speed-close-loop drive using Hall sensors for positional detection. It serves as an example of a sensor BLDC motor control system by using one of the latest members of Freescale's Kinetis and 3-Phase BLDC/PMSM Low-Voltage Motor Control Drive. It also illustrates the intelligible implementation of a BLDC motor control technique using Kinetis features.

This application includes basic motor theory, system design concept, hardware implementation, and software design. It also includes the FreeMASTER visualisation tool usage, application setup, and demo operation.
