power/weight ratios

Greg; many thanks for all that, which seems to answer my question more than adequately, and my apologies for being abusive to Paul and anyone else whom I might have offended with my last post. As mentioned I have been suffering from health issues this year and such things do make one a bit shirty at...

power:weight ratios

my original query was as to some sort of rule of thumb for motor power (meaning torque of course) to vehicle all up weight which will allow single speed transmission. I'm very sorry, you can't have one. Cedric can give you an estimate for his motor because he knows all the performance curves, but y...

in the interests of maybe making this discussion useful to others perhaps it's time to try to take it forward again remembering that my original query was as to some sort of rule of thumb for motor power (meaning torque of course) to vehicle all up weight which will allow single speed transmission. ...

I doubt that night Train and I have any real points of disagreement. Over the years I've come to realise that there is no point in trying to argue with people about their beliefs, so if some of the populace believe that humans are not responsible for Climate Change and that consequently they don't n...

why buy an EV over a hybrid

After reading a lot of comment on various forums over the past few years it would see to me that a great deal of EV support is down to dogma; ie internal combustion is seen as an evil which must be eradicated. you did ask for controversy! Given that so far the mainstream industry does not seem able ...

Richard, a small suggestion for when you make your coupling: in the forklift it gets intermittent use so they use this crude slot-drive design, but in a car it will work harder. For the female part can I suggest you make the ends of the slot closed, to prevent the two halves from gradually springing...

To answer your query Paul, I'm actually still struggling to get a clear picture of the components we're working with. Setting some sort of target, ie: clutchless-single-speed, at least gives something to measure against. Understanding motors, controllers and even batteries in all their permutations ...

I should have said, complexities in the design . I can see that for many people your approach will be simplest in terms of work, but for me it's the finished job which matters. A clutch, plus gearbox which is well over strength and has an excess of gears is extra mass and complexity which an EV can ...
