N52 magnets!

[lolzor]

Is there a big difference in efficiency and power if you change from N50 to N52? Also are the N52 magnets the strongest there is?

Found this link if you guys are interested http://www.magnetladen.de/index.php?cPath=38_40&language=en. The magnets are designed for use in brushless motors.

No, I don't thick it is significant. I have not seen any stronger. Generally, the magnet strength is related to the "N" number but not always. N52 is the magnet material. Its strength comes from how well it is magnetized, hopefully to saturation. Also, the higher the "N" number the less tolerent Neo is to heat. Check this out before purchasing. The thickness of the back iron, flux ring, or can also plays a part in magnet strength. "Leaking" flux is a waste of money and weight in our case. An N48 with good back iron will beat an N52 with insufficient back iron. Without imperical testing or computer flux analysis it is hard to tell how much is enough and how much more is overkill.
