Comment List
  • Dear ,


    I wasn't going to start on the board until I had fixed up the fan motor, but inspired by this posting, I tried to get the software side up and running.


    I too encountered this issue when I tried to communicate with the board initially - as I was trying under the expectation that the microcontroller would be powered by the debugger.


    However, for this board, this is not the case. The power required by the controller is supplied from the AC input terminals. Thus you need to provide the AC power directly to the board before starting MCE Designer.


    The communication worked, but a new error cropped up as it detected somehow I had mixed design versions. I haven't looked into it as I only have about 20 minutes before I have to go to work - but hope that you can overcome the communication issue just by providing AC power to the board.


    - Gough

  • I used the firmware at this link.!tools


    I saw the same things for the parameters. I measure in the lab with LCR meter the value of L and R (are the same on the Infineon datasheet).

    true...for the 230V just with delta connection it is possible to use the FAN.

    I was thinking that the firmware for the EMC101 was already set for this FAN. They use this FAN in their datasheet

  • Not sure if you saw my comment above with regards to the AMD USB controller causing issues - I managed to sort out my issue with changing over to an Intel-based machine.


    I was using the firmware you mentioned, and if you examine the parameter file, you'll see it does not match the specifications of the motor (and the parameters claimed in the quick-start). The shipped parameter files seems to be for an 8-pole motor with 0.40A rating, rated speed of 2730rpm and Ke of 36. I re-measured the parameters myself, as I wanted to be sure that the values were correct. Having the wrong values would often result in control issues.


    Good to hear you have measured the parameters yourself. I'm just finishing the build for my motor stand so I can safely run the motor without it potentially catching a wire or falling off a table ...


    - Gough

  • I've got around to having the fan on my stand, built the parameter file in MCEWizard from scratch for the IMC101T (with my measurements, and also another with the suggested figures where available in the quick-start), loaded it and I'm getting something similar to what you mentioned - audible noise, only a small "twitch" of the fan blade at the beginning of attempting to start the motor and no spinning. The controller definitely *thinks* the fan is spinning as does the traces from MCEDesigner, but it isn't. The configuration is definitely in hall-less mode. On the upside, it didn't trigger any faults. Measurement of the phases shows that there is a PWM-AC signal at around the intended speed and rather healthy voltage, but obviously the motor start-up sequence was perhaps too quick or didn't catch the rotor. I tried playing with the parking, open loop start-up and low speed thresholds but I still can't seem to get it started. I tried changing the Ref Speed to something slower or faster, but no change. Fan is connected in delta, as suggested by the quick start.


    Did either of you or have any luck getting it spinning? Perhaps my parameter file is not right, or there is something I am missing, or perhaps I will need to dig into the depths of tuning the drive to get it to run. Just for fun, I tried the supplied parameters and didn't see any difference either ...


    I'm not sure if any of you tried to register the product on Infineon's website either - I'm getting error messages on registering the product, but it doesn't seem like there is any extra exclusive content for those who register the serial number ... or if there is, I can't seem to access it.



    (In the meantime, I hooked it up using some old scrap appliance wire, but found it was copper-clad aluminium and it's falling apart on me ... time to savage another cord and replace it. Just my luck!)


    - Gough

  • Hi

    I registered the product on infineon website, the "special documentation" is the PCB file and gerber file.
    To register the product you have to use the name of the demoboard "EVAL_DRIVE_3PH_PFD7" and than se second code that you find on the evaluation board.

    I sent an email to the company that produces the fan to send me the parameters of the motor. now I'm waiting for an answer.

    Honestly I'm very disappointed with the kit, it's not userfriendly.

    I tested the motor in the star configuration with 220V AC. Obviously, it doesn't work.

    The motor is sinusoidal (PMSM), if you try to check the voltage on a phase with the oscilloscope and turn the fan by hand, you will see a sinusoidal waveform.
    as soon as I go to the office on Tuesday, share all the acquired data (Ls, Rs, pole pairs ...).


  • Glad you were able to access the "special documentation", as I did exactly that and got the red errors in the image above and was not given access. I wonder if something is wrong with the serial number that came with my board.


    I will ask to contact Infineon on our behalf to obtain the parameter file they used to try and get it going. I'd agree that I've had to "fight" a few issues along the way with confusing documentation and changes in software interfaces (especially MCEWizard) that make the documentation hard to follow. It's a shame that even with the parameters I have (that I think are right for the motor), I still can't get it running.


    For now, the parameters I have are as follows:


    They don't actually get the motor going, but as far as I know it should be right. Based on the RPM, I thought it was a two-pole motor, but the quick-start says it is four ... changing that didn't help. The Ke constant is also confusing to derive - this is what I got spinning the fan by hand:


    Based on f=5.13442Hz and assuming two poles, then the spin is approximately 308RPM. With Vpp of 1.9453 / 1.414 = 1.3757 Vrms. Normalising to 1000RPM, this is 1.3757/0.308 = 4.46669 V which is where I got 4.5V from. But if it was a four pole motor, then the RPM would be halved and thus the Ke would be doubled - I tried 9V for the Ke value and still couldn't get it going. This is assuming I've interpreted the documentation correctly - I may well have stuffed up somewhere ...


    I've tried raising the minimum running speed, throwing the speed ramp rate around (I tried 10, 50, 100, 200, 500, 1000). I've tried disabling open loop start-up, putting it into 10, 25, 50 RPM/sec. I've enabled parking for 1s, 3s with no change, also tried a low speed threshold of 100, 200, 250, 500RPM.


    To be honest, I've almost run out of ideas. The big question I have is the proper Ld inductance - I measured Lq just fine with my LCR and used the same value for Ld, but this means the motor has no "saliency" which might be throwing off the algorithm. I tried putting in a lower value for Ld as I suspect that is what naturally happens, but I think trying a value of 300 mH resulted in parameter out of range errors.

    In my case there is quite different bad luck as I'm still waiting for the fan. The board was delivered a week ago.

    Ah, shucks. I didn't realise you had encountered logistical difficulties ... that's a shame.


    While I have built my stand out of PVC pipe as I don't fancy trying to "catch" a falling metal-bladed 1.7kg fan if something goes wrong ...


    ... I am still yet to get more than just a short "twitch" out of it although the board did not trip a fault state and just thinks it's spinning but at an unstable speed. It suggests to me I still haven't gotten the right parameters and that the angle estimation is probably quite sensitive to that. I've put in some time to send off a support request to Infineon (as the application note mentions tests with this motor) and hopefully there will be more information forthcoming soon regarding the parameters and/or the parameter file they used.


    - Gough

  • I have not yet received a response for the parameters from the company that manufactures the fan. I hope to receive some documents tomorrow.
    I connected the fan to the power supply with 100V, but it is not possible to establish the number of pole pairs of the fan.

  • I tried to confirm that this morning just quickly, following the instructions given by MCEWizard:



    I hooked one winding to the scope, set it to relatively high sensitivity and slow time-base and spun the rotor for one revolution precisely:


    That looks to be two poles to me, rather than four poles as stated in the application note. The RPM rating and mains-frequency speed also suggested to me that this is a two-pole motor, as a four-pole should have about half the speed rating.


    - Gough

  • I have to ask about the shades of pink and green. What crayon box did you get the glue from?

Comment Children
  • - Hahaha ... that's a funny way to put it.


    PVC solvent bonding of pipes - the pink is the primer which etches and cleans away the surface in preparation for the solvent bond glue itself. The green is a type of solvent bond intended for pressure pipes which is stronger than the ordinary blue solvent bond stuff which you might see on ordinary PVC downpipe. Of course, being at odd angles, outside in the garden on uneven ground, I couldn't help but have a few drips and splatters as there isn't much time for adjustment once you get the pieces touching together. The solvent bond literally dissolves and reforms the PVC together, making the joint extremely strong and durable.


    - Gough

  • I have used a cleaner or heard of a pressure pipe glue. The PVC glue I have used is yellow with ABS being a gunmetal grey. I can appreciate wanting to do the solvent work outside. It would surely stick up the whole house.

  • It's smelly even outside, but in Australia, we don't have a choice of colours. As long as it works, I'm fine with it image. I did consider doing the same with wood, but because I have to visit the hardware store by public transport, PVC pipe would have been lighter and more convenient. Definitely not the most conventional of builds for a RoadTest, I must say.
