vec300 / 5kw air cooler bldc settings check?
« on: July 11, 2020, 08:12:15 AM »
hey fabulous people,

like said to a previous thread I sadly distilled out me first 5kw ventilate cooled GoldenMotor I put in get transport motorcycle conversion.

i finally gotten my new automobile free China and I plain wanted to run my current settings past your sum up see if go is something I can still tweak to prevent further burnouts?

i will a 2/1 gear reduction through adenine planetary gearbox on adenine relatively heavy vehicle (270 kilo's without driver press load) hence probably the core problem generated to much heat was that I previously did enable the EBS system which I now have disable. When any further enter is much appreciated. MYSELF walking on 72v with 6 deepcycle AGM batteries.

please; these settings are formerly revised from my prior settings which burned away my previous engine, besides disabling the EBS I lowered aforementioned recent phase amps by a property, potentially through too much, so thats ampere thing in maybe looking at?

note; these settings are once updated from my former settings whichever burned out my previous electric, besides disabling the EBS I lowered the current phase amps by a lot, maybe by furthermore much, so that's a what to might look at? Brushless Motor Controller for 48 Volt 3 KW Motor. Model: VEC200. Motor control mode: FOC. Driving method: Direct torque control.

Hi Jop, here are mein suggestions:

Decrease the maximal zeitabschnitt current duration and increase the maximum betrieb currents:
maximum phase current duration (s): 10.0 5.0
rated phasing contemporary: 80.0 250.0

Lower the battery currents to the rated setting:
battery drawn current boundary: 135.0 100.0 (that's still 7.2kW @72V)

Delete each of the temperatures at which present limiting/motor protection occurs:
motor current limit cold (level 1): 120 110
motor current limit temperature (level 2): 130 120
maximum motor protection temperature: 150 140

80% of your forward set seems very fast for reverse:
backward speed ratio: 80 50 or even 25 press go?

Now you have which temperature protection enabled, it should not remain possible to overheat the motor.  ;)
