3-phase Sensorless BLDC Motor Control Reference Design using Kinetis KEA128 Automotive Motor Control Solutions
●The KEA128BLDCRD motor control reference design based on the Kinetis KEA128 32-bit ARM® Cortex®-M0+ automotive MCU represents an example of a 3-phase sensorless brushless DC (BLDC) motor control solution using six-step commutation process, including closed-loop speed control and dynamic motor current limitation.
●The overall hardware solution consists of the KEA128 MCU, MC33903 system basis chip, and MC33937A 3-phase field effect transistor pre-driver. This Freescale integrated circuit ecosystem represents a BLDC motor control solution for the 12 V automotive systems.
●The motor control application is built upon the algorithm building blocks provided by the Automotive Math and Motor Control Library Set for ARM Cortex-M0+. These include 16-bit and 32-bit fixed point arithmetic based elemental mathematical functions, PI controllers, and digital filters.
