it may not work for you because you need to com up with an adapter for motor to get the encoder to work! If your handy & can 3d print an mount for the AS5048A encoder. AS5048A encoder is cheep between $7 an $14 found on digkey. I can also source if your not in the CONAS. I recommend motor with the encoder built in you just need to get a license for the encoder firmware from Basecamelectronics a lot less problems. I carry these encoder motors in a fu sizes but they are special order have not sold a lot because of the complexity in set up

hello Garug the expensive motors are the same as GB90 and GB110 you can find data sheer here fixed the URL as well as how to.

They say it is with AS5048A so I guess it is with SPI and PWM interface, do they have connectors/soldering points for both of these interfaces? would you have picture of the encoder board inside the motor, showing how cables can be attached to it?

The small motors you posted are interesting too. are the the boards included with them?

They look all good, but need to test to say for sure.

Hello, I have a gimbal that uses exclusively 6208gbm motors and I decided to take on the task to add encoders to it. Here is some of the progress and I will keep you guys updated and eventually release the STL files for each section of the gimbal. For reference the gimbal I am using is the following.

The approach I am taking is replacing the bearing seals with custom pieces that hold the magents needed for the encoders. I was not able to locate a smaller (and cheaper board like the circular one above) so this uses the 5048AB encoder evaluation board that conveniently includes a magnet and a ready PCB although its rather large its cheap and readily available.

This is the 5048AB eval kit:

This is how it looks all installed (exploded view)

Right now I am only undertaking making the Tilt shaft of the gimbal but since all the motors now use an almost standardized D25x4 3mm holes it can be easily edited to fit the other parts of the gimbal.

This was the first plate I 3d printed to make sure all the measurements and hole spacing were correct.

The bearing seal/Magnet holder does need to be modified in size in certain parts to fit the different parts of the gimbal. Here is a diagram of the design I used.

This uses the same mounting screws that were used in the old seal and has a pocket so the magnet can be pressure placed inside

Here is a 3d printed prototype with magnet fit in.

Here it is installed (Note I made it a little further out, the version posted above leaves it flush with the frame.

I should have the new board and seal ready by Monday and well see how it turns out, if it all fits nicely ill gladly post the STL/Inventor files. Also I will probably manufacture them in CF and aluminum in the future for a cleaner look and maybe some of you would be interested in that, otherwise you can 3d print your own.

very good leor!!

Good job on those. I would have ordered them in a heartbeat but I was impatient. Either way the STL files for the magnet holders are going to be the same and they are done. I will upload them soon.

New circuit board for AS5048 is a magnetic Hall sensor!

Hello Garug 10.2 ohms

I'm currently trying to tackle being able to have the encoder rotate off to the side of the motor so that you can still have wires running through the centre of it. Simon from Etec who make the GB5010/15EN motors did mention he was investigating a way to have the best of both worlds with a hollow core and encoder support. The way I am trying to achieve this is just to 3D print a geared collar that slips over the ETec GB50-10 and then have a smaller pinion gear on a bearing with the diametric magnet underneath the bearing and just above the AS5048B sensor. This seems to give me the desired encoder value changing in the monitoring tab, however since the gearing ratio is no longer 1:1 I somehow need to set the firmware to know what that gearing ratio is. I have tried setting the "Magnetic Linkage of Motor", "Motor/Frame Gearing Ratio" and Encoder/Motor Gearing Ratio however the encoder angle indicator on the dials to the right still indicate a 1:1 ratio. Yet to put a gimbal together and go through the entire calibration process so at this point I am not 100% sure the firmware currently supports this concept of the gearing ratio between motor angle and encoder angle not being 1:1. The manual seems to suggest that it currently requires the encoder to be mounted directly on the axis of the motor, so I'm puzzled why there is a setting for motor/encoder gearing ratio ? Great if the firmware does support this as the pinion gear with the magnet on it has barely any friction on the motor and allows hollow motors to be used. Could even be done by just having a pinion gear wheel with a rubber o-ring around it just touching the side of the motor case.

Anyone have some thoughts on this?

AS5048A, AS5048B both have PWM connection to BGC controller AS5048B also has i2c & AS5048A has SPI not i2c.
