Parts, Mods And Hacks / Re: Sevcon GEn4 Size4 and stronger motor for Enertia Plus
« on: January 22, 2014, 11:50:00 AM »
At Heinzmann is stated, that the pms 120 .. 156 are preadjusted for sevcon. So, it should work from stock (and it works  ;))

But I cannot find a data sheet of pms 126 - and you are right, this one is inside the enertia plus.

Know knowing ´bout the motor positon system, the Motenergy ME1114 Brushless Motor 72V 24kW has a sin/cos positioning systen, thus it should work with sevcon? Ok, I can give the answer to myself, just read the webside.

Is it easily possilbe to download a dcf file (or what ever the name is) from a size2 and upload it to a size4?

Sevcon won't work with the stock PMS120 used on Enertia. They use a completely different and incompatible encoder (SPI). You'd have to convert over to another encoder to work with anything besides the PG Drives Sigmadrive, or find another larger sigmadrive/compatible controller.

This I don´t understand. Brammo uses a Sevcon Gen4 Size 2 together with PMS 120. And - just by reading the data sheet - the Size 4 should have the same software and hardware compared to the Size 2 (except of course more power). Why should a Size 4 not work?

Hello

did you already test any modifications to the power train of the enertia plus?

From my point of view, the size 2 really limits the current at 250 amps, thus the size 4 could help

The perm 120 is not that powerfull here. I suppose the perm 150 does not fit into the frame, maybe some engine like this could help?http://www.ev-power.com.au/-SEVCON-Motor-Controllers-.html

In case of any experience, or maybe you have some parts to sell, pls contact me. I really would like to get the rubber burning (without a match)  8). Or at least, accelerate in 3 seconds to 50 km/h.
