Brushless AC (BLAC) or Permanent Magnet Synchronous Motors (PMSM) seems to be similar in construction and in working as well. Then aren't both one and the same thing? What is the difference between them?
Although a BLDC motor and PMSM motor look very similar, the way their stator wound is different and also their control mechanisms are different. I'm not saying BLAC motor here, because technically an induction motor is also a Brushless AC motor. Isn't it?
