Question:<\/strong>
\nI need to learn about the sensorless control of permanent magnet AC (PMAC) motors. Can you recommend a tutorial and\/or open source code for the sensorless motor control using the
\na) TI TMS320 series processor, or
\nb) Microchip dsPIC33EP128 series processor?<\/p>\n

Answer:<\/strong>
\nI have used Microchip and TMS320 to develop VFD<\/a>. They provide you with a demo kit, PCB and a motor. It take me half a day to get the demo PCB running with my PMSM. Then I copy their design to my own.<\/p>\n

The Microchip solution provides you with demo code. I used that before, but it require quite a bit of C programming, and motor tuning take even longer. The demo code and application note are no where near the performance of the Ti solution (I do not work for Ti -so I am not advertising). I take me a week to get my motor spinning with the demo kit from Microchip.<\/p>\n

Then there are the International Rectifier solution that is available from many years. The IR sensorless motion control solution have implemented a FOC motor control in FPGA. So you don’t need to write code for motor control<\/a>. In the chip, it also has a 8051 cpu. You write the program in C; 1 page of code will get a washing machine working. It takes me 1 day to get a PMSM motor running with this solution.<\/p>\n

I will use the TI solution for high end motor control – such as a US$40,000 dollar, 100HP direct drive PCP used in the oil field.
\nI will use the IR solution for a water pump, washing machine – things that is a few kw.
\nI will use the microchip for solution for toys, because Microchip is so much fun to play with.<\/p>\n","protected":false},"excerpt":{"rendered":"
