Hello,

I'm beginning my final exam of my study next month. I have to build an 
ec motor controller with FOC and PFC. For this reason I need some books, 
I would appreciate any hint for some good books which discuss these 
topics.

It's a 230V 3-phase motor, with hall-sensors.

Thanks

Wilfried

I don't have an Exam and i'm not on the way to get it. BUT one question: 
What please is an ec motor? AC from alternating current is know.

What is EC technology ? EC stands for Electronically Commutated and it 
combines AC and DC voltages, bringing the best of both technologies : 
the motor runs on a DC voltage, but with a normal AC supply. DC motors 
already have low power consumption but if used in an AC application, the 
power needed converting AC to DC, using a bulky, inefficient 
transformer. The EC motor incorporates voltage transformation within the 
motor. The non-rotating part of the motor (stator) is extended to make 
room for an electronic PCB board which includes power transformation AC 
to DC, as well as the controls.

EC means Electronically Commutated, maybe you know them as BLDC or PMSM 
motor.
