apart from battle hardening and something to stop shafts from moving, I’d love to see reinforced mounting holes - no more stripped threads!
I’ve done this myself by gluing nuts on the inside of the mounting holes of the motor, which works great. Not very easy to get them there though, so having this or some other solution done in production would be nice.
I have your motor from 2 years ago with no retaining ring and still in perfectly working condition. I believe because I shielded the motors from impact with a plate covering them. I think you should think about a motor cover for your mounts.
Regarding the motors themselves. Making them sealed away from dust and water will go a long way in improving the life.
Could you use a mesh that blocks water and only lets in air on a unsealed motor? For instance my phone has a mesh over the speaker that is to fine to let water molecules pass but allows air.
a) 6380 or 6384 for single-motor drives (street) & for dual-motor drives (AT)
b) 6369 or 6374 for dual-motor drives (street / AT)
c) 6355 for dual motor drives (street)
Where the 6355 size is as big as can be fit on a 180mm hanger with two 15mm belts
And where all motors are pinned from
axle slipping (rotationally) inside rotor (can)
axle pulling out (axially) of rotor (can)
And where the magnets are all battle-hardened and the windings are coated as well
I also think not having sensors in the smaller motors can make more room for bigger stators
Are you set on these sizes?
Would you rather buy a motor with these measurements and more power for a higher price or rather go smaller with the same power as the old motors for a higher price.
I am currently making a prototye for myself and would like to know what people in general prefer.
Size and performance is more important to me than cost. Size is often a restricting factor, based on skateboard design. Especially in the 6355 lengths.
Proven performance and longevity. If a more powerful smaller motor could be made that never broke then there would be serious interest from seasoned builders I’m sure.
Yes, as @BigBen mentioned, reliability is #1. If it doesn’t work, then it’s not worth anything.
So imagine the motor being violently shaken one million times while being hit with rocks and metal dust while splashing through brine. That kind of reliability.
Sealed motors, no water=rust, no stones, no grease!! This is a new one for people running gears with front open motors. I never had broken magnets, but I had axles coming out from cans like crazy
