Robot MarketPlace - BaneBots 64:1, 36mm Planetary Gearmotor, RS-540 Motor

These gearmotors are custom made for robotic applications. They feature all metal planetary gears and use two ball bearings to support the shaft. The integrated motor mounts and extra long shafts make them easy to integrate into your design and eliminate the cost and complexity of separate motor mounts and shaft extenders.

A durable, 5-pole balanced armature, RS-540 motor comes standard with these gearboxes. If this motor does not meet your needs, it can be easily replaced with any motor having a 3.2mm shaft and a standard RS-540/550 mounting pattern.

IMPORTANT NOTE:
Mounting a large load to the end of an unsupported shaft may damage the gearmotor!!!

The shafts on these motors are supported by two ball bearings making them fairly rugged; however, we do not recommend them to be used with large overhung loads. We recommend using a design that supports the end of the shaft. If it is not possible to support the end of the shaft, we recommend mounting the load as close to the face of the gearmotor as possible and cutting the shaft to length.

Poor Quality

Bad Workmanship
Mount holes off pattern & threaded to irregular depths. Mild carrier plate DD output will strip out if slam stopped or sudden reverse while loaded. Transmission can not stand stall torque of motor. Not enough grease. Treat gently and it may work for you.

Great motor

Great motors, extreme torque is great for sumobots
Mechanically I've had no problems with these motors although they are very noisy
I could not find the mounting screws in any store and ended up buying them from mcmastercarr.com, and once I got the correct size some of the holes were full of paint and required a threading tap to clear them

I ordered two of this item. I have selected this item based on detailed calculations and it is meeting them.
* Noisy
* Sounds of the two items are not similar
* I tried to unscrew them (to adjust the ratios) but some screws are not coming out and their heads are almost damaged.
* The used grease is not enough
* Material and finishing are not 5 stars
