Anywhere where the "metric-sytem" is used; there is no use of the word Horse Power, it is a forbidden-word in the Euro-Union,

COBBLERS!

The demon word - Horsepower - is frequently used - the only problem is that there are lots of different -horsepowers-, SAE, DIN, PS

I have taken numerous European technical papers - and set a few - and I have never heard of anybody being penalized for using the word - horsepower

Mind you if you tried to answer a technical question in horsepower instead of Kw I would have marked it wrong - just as I would have if you answered a distance question in Roman miles

Have you ever tried to do any serious engineering work in the Imperial system?
It's bloody hard - Rotary Slugs for example

during the "changeover" to metric.

I remember the UK as the last country in Europe to "changeover" - but that was over forty years ago!!

I was threatened in England just after the "changeover" to metric, just before starting a Marine Engineering exam, and again in Canada when starting a "Stationary Engineer's" exam also. But; I guess nobody in both countries "cares a damn" which you use theses days!! In England most "speed signs are in both! Here in Canada there was talk about doing the same, posting in both MPH and KPH.... In a lot of calculations it is easier to use metric, but that is the only advantage I can see.

Hi Electro

In a lot of calculations it is easier to use metric, but that is the only advantage I can see.

Just try to calculate driveshaft resonant frequencies in Imperial! - nevermind anything difficult

The real advantage is that SI is a designed set of measurements so that everything keys together

This is a major advantage when you are trying to understand what is going wrong

Imperial is a set of almost random units related to the size of somebodies foot and the width of a horses arse thousands of years ago

The horesepower we use for electric motors here in Europe is rather straightforeward.

it´s 1,36 horespower roughly in a kw.
all other horsepowers (EPK, IPK etc) are long forgotten, though they might be used by vague merchants to whip up the power (just like speaker-watts)

But type-plates are reliable enough to stick to the */1,36 to use in your calculations.

[QUOTE=sukusia;234146]So here is what I learned about motors from this site. I wanted to post a quick reference so newbs (like myself) do not have to sort through the sticky page.

I have always wanted to build a EV but I dont have the knowledge of the motors or the electrics involved. After reading many posts here I think I may be able to do it with help from all of you. I have mechanical skills I did a engine conversion on a Rx7 to chevy 4.3l v-6 4bbl , 700r4 trans. So here is where I am now. I posted this earlier ,I'll paste it here with the link to the pics. Any advice, info comments WELCOME.
04/29/2000 DAY ONE

Went to local junk yard this morning and removed the motor and all controls from a Nissan forklift model CWP02L25S , with a GE dc 9.9 kw 43.5 volts 1000 rpm motor GE part number 29010-8G200. $ 75.00 . Seven hours of work time from removal start till home in garage. Turned the motor shaft by hand it spun free no binding or noise. Will test it with 12v in the morning, after I find out here if it will not damage it only using 12v to test it. I am really psyched , still looking for the donor veh, not sure which one to get , either a S10 or a Ranger. I have read here that the S10 is better because of the way the motor mounts are located and it is a eaiser fabrication because they are not off set like the Ranger. Also the S10 has a better made 5 spd manual transmission than the Ranger.

no worries, you won´t wreck any motor if you test it on a lower voltage as it is designed for, if it is able to run freely.

Does this diagram look right to you

If I may assume that speaking about the front, you are meaning the Drive End (i.e. the part where the shaft exits that is going to be connected to the gearbox, and NOT the part that house the brushes) AND we can assume that the motor is wired standard, then your drawing would be correct.

Thank you so much for your reply,

I have 2 electric motors made by Polaron & marketed under the name of Nelco. It has a peak torque of 60kw. It was originally developed for medium sized buses & large vans. They have never been used to my knowledge but have been in sotrage for a while. 2 links below give some info close to the motors I have. If interested I can send pics and maybe work out a deal. You can call email me at wud10inc@yahoo.com.
