There are time to time broken GSD motors in Ricardo.ch, you have to watch regularly... Especially the ones from ET1.

Let me know if you spot such a metal workshop around Zurich area...

That would be great fix for the issue actually, why not. Then you need to distroy the aluminum stator. If you are lucky, the new DT Swiss Threading diameter is smaller than the Stator diameter and you can still replace the Stator in the worst case... But I neither have tools for threading, nor...

Actually, my saga continued another 2 weeks after the GSD fixed. I will post the details soon. In the meanwhile, I will ask Ortlinghaus about the detail if they changed my electronics or used as as - I am also very curious :)

There it is :cool: First test result: - No FW change, still my last version - No more warnings or errors :) - My old data still there - Recuperation works Second test, 1h ride in the city (mostly flat, using riding assist 1, 2 and 3): - Managed to increase the range up to 200km ...

I have rebuilt the rear wheel last week :) I used X-Tools Wheel truing stand and X-Tools spoke tension meter, they are reasonably chep and good guality. Truing process took me about 2h. I used the original spokes, but I completely replaced all nipples with 12mm DT-Swiss black nippels.

1. cont'd... I got my GSD (G45p) back from Ortlinghaus 2 weeks ago, they charged me 239.- CHF (i.o. 213.-) They changed the complete left and right housing which contains ball bearings, magnetic speed sensor, free wheel stator part as well as XD driver body. They did not tell me if they...

Hi Skotie, 1. You wrote with assist mode on, when you spin the wheel you feel force. Did you get any warning or error on the display? My one was giving some unknow engine warning/error messages. As I wrote above, 2 of the output driver MOSFETs were burned. After I replaced them, wheel was...

I knew I would have several difficulties like this when I bought this broken eBike. I got it for 388.- CHF in an auction, original price was close to 6K 4 years ago. I spent so far about 400 CHF for new parts and paint work. If I spent another 250 for the GSD motor, I am done around 1K - which...

1. cont'd... Back to # 1. (mechanical) problem, replacing the aluminum Free Wheel Stator (above) Last Moday, 11 May; Swiss constitution decided to relax Covid-19 lock-down and open primary schools as well as most of the companies in Switzerland. As a result, I could get someone on the phone...

2. cont'd... I closed the GSD temporarily for testing the electronics after I finished replacing 12x IRFB3607 and 3x L5101AM electronics components. I was positively surprised when I did not receive below errors (C64: check cabling, D300: display error, M4165: unknown error code) any more: I...

2. cont'd... I have also changed 3x IC (Integrated Circuits) so called the Gate Drivers (HMAL L5101AM National Semiconductors, which I also sourced from www.digikey.ch, price was in a dolar range per piece). I did this as a "preventive" maintanence together with those 12x IRFB3607 MOSFETs, in...

Hi @indianajo, I am happy that at least one person read my text :) My GSD seems to have a heat sink, may be they did some update, see pictures below. Blue tapes are actually .25mm thick silicon based insulator/heat coupler. They are attached and pressed to the aliminum part of the stator...

2. cont'd... I measured the N-MOSFET power transistors (IRFB3607 P512D in TO220 heatsink packaging- there are 12x, 4x per phase), 2x of them which belongs to 2nd phase was broken. (Here is the data sheet...

2. Here is the electronics printed circuit board, which makes short of the 3-phases in the stator coil wiring. How do I detect there is a short (A) even when hub motor connector disconnected, when you spin the wheel you feel an increasing force with rotation speed (called back EMF in...

1. Here is the mechanical issue in the hub motor: I removed the SRAM XD driver body and found out that teeth worn out. XD driver body look still OK, I wish this had the issue :-( ps: I could not removed the "Free-wheel stator" part yet...

Hi Guys, I am new in this forum site. I came across EBR when I was desperate to repair my Go SwissDrive (G45p) hub motor. Because of Covid-19 lock-down, all brand bicycle shops are closed, Stoeckli (https://www.stoeckli.ch/) is no exception - which they still service/repair GSD motors in...

Hope one of you guys have an advice / experience how to remove the coil assembly without damaging the magnets on the rotor side? I decided to create a new thread to blog my repair experience, you can find it here. Cengiz

Here I post some other nice close up pictures from inside of the G45p hub motor. Which I could not do so far: Remove the coils from the motor housing. The reason for that, the rotor's strong permanent magnets pull the coils metal lamels so strong, there is no way I can pull it off without a...
