Magnetic strength of Neu motor

yeah.
Please offer us detailed information about the temperature difference and running parameters.
I doubt the necessary of the "new design".Cogging is rarely a problem in my original 1515/1Y.
The Novak improves their motor performance by increasing the magnetic field of the rotor and hence more difficult shaft rotation.
Maybe the Neu goes to totally different way but that completely overthrows my concept from Novak.
