In the appliance industry, getting products to market can mean the difference between success and failure. New technologies for motor control mean better efficiency and reduced noise and vibration, now becoming a key to the customer.

Toshiba Electronics Europe (TEE) is the European electronic components business of Toshiba Corporation, ranked among the world's largest semiconductor vendors with one of the industry's broadest IC and discrete product lines including development and prototyping of industrial and home appliance applications solutions The company announced an evaluation kit for the development of embedded systems designed to control three-phase BLDC (brushless DC) motors commonly utilized in appliances. Based on the companys TMPM370 family of ARM Cortex™-M3 microcontrollers, the kit will speed and simplify the design of motion control systems for pumps, fans, robotics, and other industrial and home appliance applications. Toshiba's new BMSKTOPASM370 Field Oriented Motor Control Kit - which has been developed in conjunction with hardware and software tool specialist Hitex Development Tools - comprises an evaluation board an in-circuit emulator (ICE), an 18V three-phase BLDC motor, a 24V power supply and a comprehensive package of software tools and documentation. The kit's evaluation board is built around the TMPM370FYFG high-performance, low-power 32-bit microcontroller, which is based on an ARM Cortex-M3 core running at 80MHz. This device combines Toshiba's proprietary PMD3+ programmable motor driver technology, a vector engine (VE), 12-bit ADC functionality and a comprehensive set of peripherals and interfaces to provide accurate, hardware-based field oriented vector control of sensored and sensorless three-phase motors. All of the circuitry and interfaces needed for low voltage motor control are incorporated into the evaluation board, along with safety control functions and a small LCD for stand-alone evaluation. The software package supplied with the kit includes source code, a board support package (BSP) and a PC-based graphical interface for the quick and easy configuration and control of low- and high-voltage motor control parameters. A Segger J-Link ARM Lite USB-driven JTAG emulator for Cortex-M3 cores further simplifies application development. Comprehensive documentation includes application notes, reference designs and bill of material (BoM) information.
