Ideas for a motor "cushion"?

[thrak76]

We know that the motors are susceptible to being damaged from smacking the chassis on hard landings.

What can I do to mitigate this?
I've seen hot glue, 3D printed parts, etc. I'm curious what (if any) folks may be using on their rigs?

I was thinking of some foam "packing material", neoprene pads...

Was thinking something of the same. Irs what I use under my . Works well

I'd just use a thick-ish craft foam that has adhesive on one side.

Some type of rubber not too soft. Double-side tape to chassis.

Typo? Irs?

Good ideas. I have some of the toolbox drawer liners. Maybe a couple layers...

Put a rubber on your can

Ding ding ding, we have a winner!

Hitting up ebay now for some o-rings. Great idea!

Just a helpful tip, get ones with a smaller ID than the OD of your motor so they don't move on you. If your motor can is a 40mm diameter, then get 35mm ID rings. Try to get ones that are as thick as the distance between your chassis and motor. You don't want it to push up on the motor, just take up the gap.

35mm was exactly what I was looking for!

McMaster-Carr part #9262K96 work great for the 49mm cans. They have all sizes also.

Just be mindful that the motor is going to heat up and transfer that heat into whatever you use to pack it………. Anything rubber won’t last long.

Yep......its*

You could drill and tap 3 4mm holes into the chassis underneath where the motor is located. Cut out abit of sheet metal and place that in between the motor and chassis. Wind the bolts in to prop/wedge that sheet metal up in place to where you want it. Have a third bolt through the sheet metal at the rear of the motor to hold it in place so it doesn’t slide out. Use locknuts too if you can get them on.

Or simply buy a $0.25 rubber ring and slip it over the end of the can....

Actually… they cost $0.97 at my local ACE Hardware.

Jb weld it... never have to worry about the motor shifting anymore either

 

[Surchaufeur]

What if we run a heatsink

How to you service it then?

You buy a new rig of course

And how long is that going to last…… it’s not sitting on the can in a neutral position…… it’s stretched right????…… add in the heat factor of the motor, vibration plus up and down ambient temperatures……. That sucker will start cracking and moving all over the place if not snap………. Band-aid fix mate …… definitely nothing permanent.
