Fujitsu Microelectronics America, Inc. (FMA) introduced
a motor control starter kit equipped with source code to support
development with the MB91F479 32-bit
RISC microcontroller for industrial motor
control applications. The new kit is geared towards driving a 3-phase
(BLDC) or permanent magnet synchronous motor (PMSM) that are commonly
found in washing
machines, air conditioners, refrigerators, and other consumer white
The kit has a modular two-board design that includes an inverter board
as well as an MCU board with preloaded
demonstration software. The included software libraries are optimized
execution for PMSM and BLDC motors. The libraries support hall sensor
methods and the advanced sensor-less back-EMF algorithm for BLDC motor
control, and FOC sensor-less control capabilities for PMSM motor
control. Using these libraries, the user can evaluate a
solution ranging from traditional sensor-based techniques to advanced
source files and the bill of materials (BOM) come with the
enabling the PCB design to be reused for other target applications, a
plus for getting new motor control designs up and running.
The kit is capable of driving a motor up to 5W. Push-button
switches on the MCU board allow users to
monitor the motor performance via an RS232 connection to a PC terminal.
The kit can run with the BLDC motor in sensor/sensor-less mode or
with a PMSM motor in sensor-less control.
Three speed-control demos (PMSM and BLDC) allow users to
evaluate the motor control, system tuning, and different speed
The MB91F479 MCU is a new member of the Fujitsu
32-bit motor control family, which incorporates motor control
peripherals like multi-function timers and dead timers for generating
the three-phase PWM waveform that drives and controls motors.
The motor control starter kit is available now at
