How to improve cooling in Cyclone motor?

Post by andrenoites » Nov 18 2013 9:31am

Did anyone tried to improve cyclone cooling by adding thermal paste between the stator and the motor housing?

The thermal sensor is in the stator and it will cut off power at 85ºC
At this temperature the motor cover it's only at 48ºC so I think there is much room to improvement here.

No need to add aluminum cooling fins until the contact between the stator and the housing it's fixed. It just isn't efficient.

Cheers,
André

What about oil cooling, seems to have worked with hub motors.

It's a idea!
But still I would prefer something more simple and less messy

I saw a Russian guy put a blower on flat part of the casing (red) and drilled holes (green), 7000W. His blog is offline now... :(

André, és da região de Lisboa?
Thank you Justin! Life is so much sweeter with this forum... ;)

Yes, he stuck a fan on the motor similar to an alternator http://endless-sphere.com/forums/viewto ... =2&t=42812

For my first ever e-bike build a new housing was made for the cyclone motor.

I lived in Spain back then and especially during the hot summer month the motor overheated quit often.
After this modification it was run at approximately 1,2 Kw and never failed again. :mrgreen:
