Development System Slashes Time To Design Motor Controls

Promising to slash the time needed to design motor controls from several weeks to just days, the IRACS201 development system employs the Accelerator Design Platform to achieve a design flow that requires no coding to configure motor control algorithms. The platform includes: a mixed signal motion control chipset; a FPGA-based, configurable DSP offering parallel processing capabilities and customizable peripherals; high voltage ICs for gate drive and current sensing functions; and an IGBT-based power inverter stage. The bundled software includes ServoDesigner, a Windows-based configuration tool for mapping internal registers to configure motor type, tune control parameters, monitor/diagnose internal signal waveforms, and more. The development system reportedly enables an advanced field control (FOC) and PWM algorithm loop to be executed in under 4 µs versus as much as 15 to 20 µs for a programmable DSP-based control loop. The IRACS201 price of $9,500 includes a 1.5-kW servo amplifier platform with pre-loaded code and ServoDesigner. For more details, contact Wayne Yoshida at INTERNATIONAL RECTIFIER, El Segundo, CA.
