I have taken several undergraduate courses in physics. If you have some clue what they are saying with:
> In some applications, these motors could offer an overall boost in efficiency ranging from 30 percent to close to 100 percent
please illuminate. Brushless DC motors across a wide variety of applications already exceed 50% efficiency. Perhaps there are applications in which they cannot reach 50% efficiency, so a 100% boost in efficiency would be possible.
- eightysixfour 2y agoThe key is “in some applications.” Not in all applications. There are areas where brushless DC motors are inefficient, these are better in those areas - my guess is low speed, high torque use cases.
- aidenn0 2y agoA) that's the sort of thing I wish the article had mentioned. B) I know it's research, but low speed high torque situations usually involve a reduction gear-set. They make some surprisingly compact ones these days.
- eightysixfour 2y agoB) Yes, which involve losses and packaging changes. Exactly why a motor like this would be useful…
