Same old same old from Ausheds. Mate it goes like this: some manufacturers will choose to make the cheapest permanent magnets possible by eliminating Dy and reducing Ny accordingly. Other manufacturers will spend a little extra and use Dy and Ny and get as much performance to maximise efficiency in their chosen application. Just like cars now - some manufacturers designs perform better than others. Give NTU a chance. BTW I notice you’ve been slagging off ARU as well - move on mate everyone’s bored of it.
