Hi there!

The story is pretty short.
In a endurance race my G25 started to smell weird, and suddenly the FFB lost power. Sadly, my wheel is out of warranty so i just opened it and discovered that the right motor was completely burned. The left motor has the optical encoder and works fine.
So if anyone of you has a extra G25 motor, I'll be very pleased to buy it.
Best Regards from Chile
C'ya!

PD: Sorry for my english.

Aren't those motors just regular small electric motors? Just like the ones they use in rc's ?

Thanks for your advice.

Yes, i know thats is hard to find someone that could sell a motor, but i have read about people that smash their G25 (by logitech orders for the warranty deal).
Maybe some of them still has parts of the wheel and maybe the motor, or someone has a broken G25 and wants to sell it.

I don't know, but hope is the last thing to lost

No, is not the same. There is something called "cogging" efect it's like non-current torque. If you spin an generic electric motor with your fingers, you will feel that the motor goes in steps. So if you put a rc motor in the G25, the wheel will feel "shaky". In a low cogging motor like G25 uses, you don't feel that's steps and that's makes smooth turns in the wheel.

Maybe you can make some photos of the inside and the motors. And show us whats inside.

Those motors can't be opened easily

I don't have a G25 motor for you, but i do have a DFP motor here. Probably the same motor, the differences between the wheels is caused by something else by my knowledge.

You could still try to email Logitech first. They have a great customers support and seen as this is one of their more expensive products, i guess they will have a solution. Just try it, who knows what they will say

Some time ago i wrote to logitech asking if they could send one motor to me. The answer was that they don't send parts. They send another wheel in case of warranty, but they don't send parts or in this case motors.
There is no Logitech technical assistance here in Chile, so my only way to repair the G25 is by myself.

I believe that there is a difference between a DFP and a G25 motor.
The first difference is the spin ratio between the motor and the wheel. In a DFP the ratio is 35:1 same in a MOMO. In a G25 the ratio is 16:1. But that can be solved adjusting a gear ratio.
I don't know if they works with the same voltage. And maybe the torque and the RPM aren't the same, but i got nothing to lose if i try.
I will really apreciate, if you can (and want xD), send to me that motor. I believe that it can be fitted to the G25.


Best regards from Chile


PD: Oh! About the motors

This is a normal DC Brushed Motor



And this is a "low cogging" DC Brushed Motor.

May be you can find a talented guy around the corner that can repair electrical motors for cheap. This kind of dude nearly disappeared in most advanced country (no offence here), but maybe there are still some remaining in Chile. Wiring (I mean coil winding) and (carbon) brush are two things that can die and that can be repaired.
Is there any trace of part number onb the motor itself?

No, the motor itself doesn't have any information. But what i know after searching and looking in internet is that the motor is a "Johnson Electric HC685LG-011".

I know that the coil winding and the carbon brush can be repaired, but will be so reliable as the original? Another thing is the axle bearing, looks like damaged or worn-out (i said good?) because the axle has to much friction. I don't know if the axle bearing can be replaced, you know is too small 1/8 inch.

Anyway i'm trying to open the motor and find out exactly what is wrong. Maybe the axle bearing just needs a deep clean and a drop of oil, but at same time i'll keep searching for another motor.

May be try their brazilian sales location, act as if you were a company and request two samples. It often work on electronic parts.

Tu ingles se entiende muy bien!

Here is spec about FFB motors for G25/G27
