eq_3 Besidesloctite which is a good idea, you should also use thermal paste or thermal pads between the motor and the housing. The motor has a 2cm air gap and so the cover could be mild warm but the motor inside to be blazing hot and if the magnets pass over 95C they get permanently damaged. I used a lot of thermal paste which help a bit. Still, is not properly configured for more than 350W continuously. One annoying part is that i limit the amps to 9A and still by measuring the amps with a dc amp clamp i see it peaks 13.6A @ 50V which is 680W !! Anyhow, with a bit of care it should last a couple of years. The range with 48V20A is around 80~85KM with 100 kg rider, so it's very efficient.
