IR debuts motion control development system, control algorithm library

El Segundo, CA—To reduce motion control system design time and support its iMotion integrated design platform, International Rectifier (IR) recently launched its IRMCS203 motion control development system and IRMCO203 Intellectual Property (IP) library of motion control algorithms.


El Segundo, CA— To reduce motion control system design time and support its iMotion integrated design platform, International Rectifier hat development time is drastically shortened from tens of weeks to just days.

IRMCS203 comes with proven analog and power stage hardware designs, as well as the software needed to achieve a design flow that requires no coding to configure motor control algorithms.

IRMCO203 algorithm is a licensable object code IP library for sensor-less control of permanent magnet motors featuring high starting torque and smooth ramp-up. IRMCO203 is targeted for low cost FPGA applications, eliminating the need for complicated programming processes. The digital control section uses IR's Accelerator configurable control engine system architecture, using parallel processing and customizable peripherals. The analog section uses high-voltage ICs (HVICs) for the gate drive and current sensing functions. The power stage is based on the latest non-punch-through (NPT) IGBT and PlugNDrive integrated power module technologies.

The company adds that co-designing the analog and power stage hardware with IR's high voltage gate drive and current sense ICs enables fast parallel processing architecture. The sensor-less IRMCO203 enables high-speed operation (demonstrated at more than 100,000 rpm), wide speed range, high PWM carrier frequency (up to 50kHz) and fast computational update rate (up to 50kHz).

IRMCO203's software includes a Windows-based configuration tool, ServoDesigner, that is used to map the internal registers to configure motor type, motion peripherals, control mode, tune control parameters, and monitor and diagnose internal signal waveforms.

'Accelerator system architecture, in the form of a configurable DSP control engine with object code libraries, integrates with IR's proven analog and power stage hardware, simplifying design and maximizing performance,' says Toshio Takahashi, director of IR's Digital Control IC, Consumer and Industrial business unit.
