Re: Motenergy ME1304 motor with SEVCON size 6 on Dyno

Spoke to John at Motenergy, the 1304 number means it was designed in 20"13", and it is the 4th unique configuration of a product that they designed that year. So what? How it's can help for us? Number ME913 mean that in 2009 year John has work more productivetly and made 13 configurations of one mo...

Re: Motenergy ME1304 motor with SEVCON size 6 on Dyno

Can you make test of rated power of your motor? An example, can you rotate your motor about 15 minutes at half of maximum power? Wow, it is complicated. No enough battery and no coolling yet. At the moment it gets hot in seconds I will do a log when I test it in the kart. Mainly for temp What batte...

Speaking of Motenergy, is there a pattern to their names? 1304 = xxxx?
It's look so, but some motors named with another way like my DLC-28 (ME1302). The production line of Motenergy motors not so big, so I think that thay don't encrease four digits!

ME1304 has 8 magnets (4 poles). It's possible to try to rise up headroom factor to 95%.
The field wekeneeng must begine to work when headroom factor reach up set value. You can get 10% plus power if you encrease headroom factor.

Motenergy gives Ke=0,021 for ME1304, Ke=0,032 for ME1302, Inductance 66 mH for ME1304, 75 mH for ME1302. It's data from official motenergy dcf files. :?: :?: :?: Logic tell to us that with the same magnets ke must be proportional to inductance. My DVT only check inductance of ME1302 and it's matched...

Re: Motenergy ME1304 motor with SEVCON size 6 on Dyno

I plan to use combined cooling water plus air. I have calculated heat dissipation and deside that additional air cooling can give for me minimum additional 6 kW of rated power (15 kW+6kW=21 kW minimum or more). Now I have no time tо check it! If you make additional air cooling you can check it at yo...

Good job! Good power!
Why controller can't hold max power from 3500RPM to 5000RPM?
Can You make test for max power at long time period?

Hello Oliver!
Can You save your dcf from sevcon and send it for me?
I will try to understand your motor parameters.
Also you has abbility to rise up votage to 100 V an example and take more power from your motor!

Re: Motenergy ME1304 motor with SEVCON size 6 on Dyno

At the second picture with ME1304 you can see graph with 150V battery and sevcon 110V nominal controller. And you can get 30kW(41 hp) from your motor only if you increase voltage. With 120V battery power of your motor never rise up more than 25 kW (34 hp).

Also the Drive Wizard program dated 24.03.2009 works excellent with the same dongle.
