Motor Control Reference Platforms
Renesas Technology Europe developed over the last years several motor control
references platforms to address the most advanced requirements like: sensorless
control, one shunt current detection, field oriented control. The platforms are
suitable to speed-up the development time by providing Software, schematics,
Gerber data and specific user’s manuals.
Please contact us for more
information on how Renesas MCRP’s can come to your aid during development and
evaluation.
