First Power Up - 10kW Brushless DC Hub Motor

Re-uploaded because the original file was corrupt.

Everyone is excited about Graham's new Hub Motor that just arrived. So we powered it up from a random controller that was lying round.

Nice but I doubt this is 10KW motor that is 100V@100A or similar.

@electrodacus

That is correct. The controller being built for it is rated at about 250A.

Nice work!

you sound South-African, are you? If so where are you situated?

Keep well!

Yes I am South African but I am now living in New Zealand.

Seems like there are more South Africans here than back in South Africa.

nice last vid had some bad lag :) what voltage are you planing to work with?

[Paul375]

In the application I think it will be just over 100V.

Will have to ask the owner to confirm that.

In the video it was at 60V and the current was limited to 5A.

so where did you get the motor?  What was the cost? Nice no load test.

@Artist334 I 've read. 72-96 VDC. anyway... if this is a 10KW engine.... it is the SMALLEST 10KW engine I ever saw. Considenting is a brushless DC motor (eff. typ 83%) I bet It can't run "cold". Typically a 10 KW engine is a HUGE air cooled heavy engine. Anyway 96V for 95 A means 9KW pulling a motorcycle of 180Kg! Anyway tnx for the website from Enertrac.

@mptrax it is actually 10KW with 30KW peak... Check Enertrac hub motors

[mptrax]

this is what 10 KW looks like:

Something near to 35 Kg engine.

@electrodacus absolutely. It can't be 10 KW ! this is between 1 - 1.3 KW in my opinion. For Ferrari.... are you kidding me ? :D good luck.

[electrodacus]

@mptrax This is not a 10KW motor so if you use it at this level it will burn.

At this size you can not build a 10KW motor at least not with special cooling.

The 540 HP Ferrari is much larger and has water cooling extremely important.

[mptrax]

@electrodacus What ? You have a 10 KW engine just to use is at 1/10 of its power ? Are U sure it's a good idea ? Man, if I have a Ferrari 348 having 540 HP... I don't plan to use all 540 HP all the time. I need to accelerate, breaking , idle.. etc etc. Just in case your engine is VERY badly projected (ie some 1st generation Chinese engines) It could be able to reach temp. over 80 °C in everyday use. Cheer.

[electrodacus]

@mptrax It can be even 200V no problem the problem is that a motor that size can not use 10KW continuous it will be red hot at that level. My guess is 1000W to 1500W.

[mptrax]

@electrodacus I think is 48 or 72 V
