Dear all,
Firstly, apologies for writing in English. I thoroughly enjoy reading contributions on this forum, but alas, have to rely on machine translation tools to understand.
I have a low power crank drive (a GSM motor - a clone of the Bafang BBS01) in my old but functional Alligt Alleweder A4. I usually run it at low power (no more than 8A, most of the time 3-4A). However, recently there have been a number of roadworks on the quiet roads and bicycle paths on my commute, which means that I have been having to 'swim with the traffic' on some relatively busy roads.
As a result I've been using the motor more to avoid holding up the traffic, and the motor has therefore been getting warm.
Does anyone have any experience with cooling such a motor in a velomobile, where there is less airflow?
I think that I saw a photo of somebody on this forum who had a BBS motor, and had attached a fan to it, but foolishly did not take a note of which thread it was. (I don't think it was on the pedelecs forum - thus I'm asking here first).
I would also like to add more cooling on the motor if I ever close the foot holes (which in turn will have to wait until I get shoes that allow cleats to be mounted in the middle of my foot - as my attempt to modify existing shoes resulted in shoes that cannot be easily clipped or unclipped!)
Many thanks for any help that you can offer,
Regards from Scotland,
Phil
