34.6.5 Summary
What is Discussed in the above
The physical principles of the operation of a PMBDCM have been discussed which lead to the development of the necessary parts of a power electronic controller. One specific type of current control, hysteresis band current control was explained in detail, and one specific type of switch logic pattern was developed. The exposition has included many of the issues that can cause difficulties for controller designers if they are not careful.
What is Not Discussed in the above
Many PMBDCMs have more than one pair of poles. The arguments above can all be extended to higher pole count machines, by taking any mention of degrees to be electrical degrees rather than mechanical degrees. The controller ...
