Re: eZee motor and controller at 69 amp phase?

At http://www.ebikes.ca/shop/conversion-ki ... ottle.html I've read the stall torque at 36v. It is 70.7 N*m.
And with the same controller at 48v the stall torque would be 70.7 * 48/36 = 94 N*m ?

Re: eZee motor and controller at 69 amp phase?

You should go to http://ebikes.ca/simulator and see what it says about overheating for your proposed setup. Also: Are you sure you mean Phase current, or Battery current? If Phase, how are you measuring it? Of course, I took the phase current value from the motor simulator at ebikes.ca. I pointed 7...

eZee motor and controller at 69 amp phase?

Need about 78 N*m (58 lb*ft) torque for climbing up on 19% incline 300 m long at speed no less than 5 mph (and then climbing up on 5% incline 8 km long). 113 kg weight. EZee motor users, what would you say, is the eZee 250 rpm motor and controller capable enough to withstand 69 amp phase current at ...

Re: LightningRods mid drive kit

LightningRods , may I ask you about your kit for the Surly Big Dummy bike? Is the right side mount plate the same as the right side plate? Is the lower jackshaft housing and the axle the same as the upper one? Are the adjusters differ? And what is total width of the mounted kit from the left side c...

Re: Direct driving with a mid-drive kit????

What would be the lost energy percentage for each belt driven, gear reduction? And do chains loose more energy? And what other losses are there? Like the motor it's self can't be 100% efficient....? Some one should do a graph of that motor from the LightningRods kit, Total transmission losses from ...

Re: Direct driving with a mid-drive kit????

Sorry for my misunderstanding of your first post, Hugh-Jassman . (I should like to see the practical power chart of the motor too, but don't know who will measure that parameters) If we input your parameters (400 lbs, 18 mph, 8% grade) to EBike Powercalc Rev6 then after some calculations we can see ...

Re: Direct driving with a mid-drive kit????

Ok, I have been racking my mind for a way to avoid using the bikes gears from a mid-mounted motor. Because I think it may produce too much chain wear from driving up our 8% grade with about 350-400lbs too often; and the gear changing problems. This would last longer if I were to run a heavier BMX c...
