What are the advantages of IPM versus surface mount magnet motors ? i have been reading they are higher efficiency and higher torque per mass then when the magnets are mounted on the rotor surface, and they also allow higher RPM as this also stops the magnets flying out !
"Switched reluctance motors are now routinely pushing 94%-96% and IPM motors run as high as 98+% using
standard steels and magnet materials. "
Which ebike motors have this design currently ? it seems most like the bafang BBs02 and GNG have the magnets on the outside of the rotor?
