Upgrade/Replace Brushless Motor Magnets By Jaronv in Circuits Electronics 24,931 171 21 Featured Download I have salvaged quite some motors from old printers and used them for various projects, but these usually use inferior ferrite magnets (Like those flexible fridge magnets). They are not very strong so the motor strength is limited.

On the third run, small pieces of the magnet glue started flying off, then a magnet moved down into the rear housing. I think it wasn't balanced well, and the vibration loosened the crappy glue (it was a cheapo Turnigy motor). Too bad, because if the motor had been made better, it seems to have good potential for power.

Politubes enlarges its range of heat shrink tubes for brushless motors (SPM surface permanent magnets), with a the new generation of Class F- H, B-Stage epoxy resin coated tubes in order to achieve a solid bonding to the rotors.. Cure the glue between magnets and rotors. Activate epoxy resin inside our tubes for a perfect bonding. Heat.

How to Glue Brushless Motor Magnets 2013-05-31. When building models, be they planes or boats or robots, the ubiquitous motor of choice is the brushless motor. The reason for this is power and longer run times. A motor with brushes has current running through them into the center of the motor. After a time, friction can cause wear, resulting in.

Also used CA once in the past. Fine for low power, but high power or more rightly heat, made the CA let go. Loctite generally lets go with high heat too, but higher than the mags should be exposed to. I keep mine below 60degrees if I can, 80 max, and the loctite holds up.
An Introduction to Brushless DC Motors
What glue do you recomment for the motor magnet? One of the magnet of my BL motor went off. Still want to save this. Epoxy steel? Super glue?. I will check on Monday when I am at work. If its good enough for a 500 mm dia brushless motor, the magnets are 120 mm x 70 mm x 20 mm. Sep 14, 2015, 06:06 AM #10; DYORD. DYORD. Registered User. Thread OP.

For a permanent repair all the magnets would be removed, the inside of the flux ring cleaned of all the old glue, and then re-gluing all of them with a batter adhesive would be in order. As far as the better adhesive, the debate rages here. Some like epoxy, some like JB-weld, and others use various CA adhesives.

Just glue the magnets back in place using thick CA or epoxy. Pay attention to polarity, the sequence should be N-S-N-S etc. You can use any household magnet to check that each other motor magnet attracts it and those in between repel it.
