From International Rectifier exist two Reference Kits for Motor design.
IRADK31 use 2A 500V Mosfets and a PIC Controller for BLDC IRADK10 use 10A 600V IGBT for induction motor
We ordered the IRADK31 kit and experience was negative for several diffrent SW and HW reasons. Current limiting is done by the DC bus current only and the connected single phase current feedbacks are not implemented inside firmware at all. It seems, they have stopped the project at IRF becouse the firmware writers failed for unknown reasons. Probably the PIC controller reaction time is much too slow to protect the semiconductors in case of short circuit.
There is some more hope for the IRADK10 kit for induction motors. Unfortunately this kit was already obsolete in 2005. Its brief PDF documentation has been written in 2002 and is still Rev1. We also failed to find a dealer with a IRADK10 at stock. It seems that kit was also only available for a period < 2 years.
If there is somebody in the world with a IRADK10 kit in the drawer, it would be nice to share his experience. Even a copy of a readable diagramm and the firmware of included CD would be helpfull for examination.
Motorola also offered a small induction motor reference kit (with 58F600 hybrid CPU) but this one seems also obsolete.
There are reference boards using the Mitsubishi IGBT Modules but without any microcontroller, current limiting or PWM puls generation.
Any obsolete and used kit in the drawer ? Any more ideas for small induction motor reference kits ?
