Re: Raised Bed Gardening - Cement Blocks!

I did not know anything about community gardening in other countries before I read this topic. (In my country there are such things as dachas, but this is another matter) I assume that you live in the country where agriculture is really great and excellent and I just wonder why you buy seeds from Ch...

Re: electric vs gas theory

So we can say that locomotives and ships that have electric transmissions were first hybrid electric vehicles. As for railway histories, in USSR the Fairbanks-Morse Model 38D-8-1/8 was 'reverse-engineered' in the late 1940s to the Model 2D100 diesel and long lived as a prime mover of TE-3 freight lo...

Thanks Dr.Electric.
(I would like to install that motor into a 20' wheel but a strong non-folding frame for 20' wheels is a hard-to-find item at my location.)

Re: 2 speed gearbox/jackshaft

Interesting.
But maximum input torque is 40 N*m, so maximum output should be 80 N*m. Is it capable for about 50 N*m input and 100 N*m output?
How to link a motor to the gearbox?

I highly appreciate your answer eTrike Still haven't made decision. I understand that my conditions are too close to eZee' limits. I'll check % at the steepest part of that incline more accurately.

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...
