Replacing ceramic with neodymium magnets.

[Skedgy Sky]

I have this motor that's been floating around my place for a bit. It came off of an e300s broken electric scooter (motor controller was broken? not sure).

I don't know if it's a good motor for anything more than it's rated for (250 watts) but seeing that one of the magnets fell off... Is it possible to swap these magnets out for neodymium ones? What sort of performance increase would I see? Has anyone else ever done this (I didn't find any posts, but I may also not be using the right keywords)? I'm just curious of the whole idea since ceramic magnets are rather wimpy compared to neodymium.

Where would you get Neodymium magnets shaped for the application?

I have seen many small flat bar magnets grouped to form a larger magnet. It can be done. Also go to otherpower.com and/or fieldlines.com and follow the ad links for good neo battery suppliers.

I don't think it's worth the trouble, but if you're having fun and learning stuff, pay no attention to anyone, even me.

Not worth the hassle with that motor..... I have burnt one up very easily as the coil assembly saturates quickly when driven not much above its recommended specs. Best thing you can do with them is drill some holes in the case an blow good air through them with a computer fan or similar. Therefore It's not got enough 'unawakened potential' to be worth the effort investing in better magnets. Also, for the cost of good Neo mags purchased alone, you would be better off investing in a better motor to begin with. In that size category, namely a brushless one with an operating efficiency better than the mid 70's like those mass produced flea-market specials made by Unite.

Thanks for all the replies.

I ran the motor while holding two kinds of magnets with it, and found it spun up a lot faster with a neodymium magnet (not sure about speed though.. probably also faster).

My other idea with this was to maybe convert it to a brushless motor.. possibly to use with a scooter wheel... especially after I started to try disassembling the rotor.

For now it seems like a project for the future.

(not sure about speed though.. probably also faster).

In which case the Neodymium magnets are creating a weaker field than the ceramic ones....
