Fujitsu's new motor control starter kit based on 32-bit RISC microcontroller

Fujitsu Microelectronics has introduced a new motor control starter kit based on MB91F479, 32-bit RISC microcontroller for industrial motor control applications.

This new kit is suggested for driving a 3-phase brushless DC motor (BLDC) or permanent magnet synchronous motor (PMSM) found in washing machines, air conditioners, refrigerators, and other consumer white goods.

The "ready-to-go" kit saves initial hardware and software set-up time, and can run quickly after starting up. The kit's modular, two-board design includes an inverter board and an MCU board with preloaded demonstration software, which is different from the BLDC motor assembly.

Fully tested software libraries are optimized for real-time 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.
This kit comes with the source code and a ready power supply adapter, normally missing in these kinds of kits. OrCAD PCB design source files and a complete BOM for component reference are provided to reuse the physical design for different applications. The circuit is built on two-layer Printed Circuit Board (PCB).

This microcontroller kit can drive directly the motors with power rating up to 5 Watts. Motor performance data is fed to PC through a RS232 cable by pressing the push button switches on the board.

The kit can run as a plug-and-play demonstration or as an "out-of-the-box" solution, with the included BLDC motor in sensor/sensor-less mode or with a PMSM motor in sensor-less control. Three ready-to-run speed-control demos (PMSM and BLDC) allow users to evaluate the motor control, system tuning, and different speed reference profiles quickly and efficiently.

"This excellent new design kit can be used quickly with our high-performance, RISC-based MB91F79 to develop user-owned applications. The easy-to-use and modifiable software library for PMSM and BLDC motors can significantly save users development time and effort in algorithmic development," said an FMA spokesman.

This kit is priced at $650 each and is available now.
