    Test assembly of the carrier.

    So the MRA049 ring (Magnet for RLS) is press fitted on the output.
    Then the output is press fitted on the carrier and then screwed together.
    The housing have a NSK 6705 bearing. The output is resting on the OD of the bearing.
    A bit overkill. The housing also have room for a NSK 6703 bearing which the carrier is resting on. This is to minimize any type of movement on the output if any extended load is placed on the output.

    Then each of the carrier (pc1 / pc2) parts have a internal BR106 bearing which the drive shaft is resting on.

    (still wating for gears)

Hello! First of all, I have to say that this is an awesome project, I like it :) I have a question: how can you assemble the rotor of RI60 with the output shaft? It seems that the RI60 rotor doesn't have holes for the screws!

  Are you sure? yes | no

Starhawk wrote 02/09/2022 at 06:23 • point

I have to say, the name intrigues me...

I assume you're developing this for, erm, non-automotive applications, though? ;)

  Are you sure? yes | no

Robin Fröjd wrote 02/11/2022 at 22:24 • point

The name is just a name  (reference to knight rider.) :) applications is non. Bulding for the fun of it.

  Are you sure? yes | no

You just keep delivering incredible designs! Awesome! I am already curious to learn about the technical details!

  Are you sure? yes | no
