STMicroelectronics STR750 Motor Control Starter Kit

The STR750 Motor Control Starter Kit, from STMicroelectronics (NYSE: STM), is built around the 32-bit STR750 microcontroller, which enables the rapid development of high-performance vector-control applications, using both Permanent Magnet Synchronous Motors (PMSM) and 3-phase AC Induction Motors, for cost-sensitive appliance, industrial and HVAC (heating, ventilation and air conditioning) markets. The kit includes all the necessary firmware and hardware – including a 24V DC permanent magnet motor for initial evaluation – to allow the user to be up and running within minutes, and to continue through to development of the target application.

STMicroelectronics STR750-MCKIT Motor Control Development KitThe STR750-MCKIT is based on the highly integrated STR750 MCU, with ARM7TDMI CPU core, whose rich embedded peripheral set includes a PWM timer with three-phase motor-control features, synchronized with a high-speed analog-digital converter, designed to simplify the implementation of complex vector mode projects. Optimized and fully documented C firmware libraries for the control of both motor types are provided free in the kit, ensuring that most of the motor-control section of the application is already developed. Designing in the industry-standard ARM architecture saves development time compared to the use of a proprietary architecture.

The same hardware platform can be used for both PMSM and AC induction motors, operating at up to 48V; schematics are provided to minimize hardware design time. The kit allows real-time control and monitoring via a PC-based graphical user interface (GUI), or standalone operation using on-board push buttons and trimmers. Segger/IAR J-Link emulation is included, and the Flash programming and real-time debugging capability allows the same hardware and firmware platform to be used from evaluation through to an advanced stage of development, removing the need for the user to build a platform before starting work on the target system. A debugger and programmer are also included.

The STR750-MCKIT is available now, priced at $895, including a 24V DC PMSM. An AC induction motor for use with the evaluation board can be ordered separately.
