pg15_FE

PROCESSING
MCUs with associated motor-control libraries

  • STMicroelectronics’ STM32
  • NXP’s Kinetis E1xF ; V3x/V4x/V5x
  • Microchip’s PIC32 MK, MC or ATSAMD5x/E5x or dsPIC33EP/EV
  • Cypress’ PSOC or FM4
  • For high-end application (industrial robotics, very high-speed, >100k/rpm or high precision. FPGAs such as Microsemi’s SmartFusion 2 SoC (Cortex®-M3 + FPGA) with motor control algorithms implemented in FPGA. Software enablement is key is motor control.
  • Microchip’s motor-control library, simulation tools, motor bench development suite and many reference designs help customers to make optimised control on various targets for 8-, 16- and 32-bit options.
  • NXP’s Motor Suite is an easy development suite BLDC/PMSM; Motor Control Application Tuning tool (MCATSW) or Real-time Control Embedded Software (RTCESL). NXP also provides Freemaster, a real-time debugging tool which supports non-intrusive monitoring, debugging or optimisation.
  • STMicroelectronics’ motor-control software development kit, X-CUBE-MCSDK, comprises a rich selection of control libraries (FOC/PMSM, MTPA, flux weakening, feed forward control). It provides a GUI to accelerate the configuration phase. Automatic code generation is provided and the motor profiler is also proven to detect motor parameters.
