Just letting you know, DRV8301 and 8302 are not compatible.

What’s inside of the ESCape? DRV8301?

Did anyone else had this DRV fault?

SOICDIP · January 12, 2018, 5:36am

Yup, SPI controlled.

I have messaged you.

Stevemk14ebr · January 13, 2018, 1:47am

I’ve filled out the form for the group buy, will payment and such be soon?

Eboosted · January 13, 2018, 1:47am

Thanks @stewii I’ll take the pictures and send them over to you

scepterr · January 13, 2018, 1:50am

I don’t remember what quantity I filled out, I’ll take 2 with housing, should I resubmit form? I would also take an additional 2 single housings with PCB cover

What is ERPM and size of your motor?

Eboosted · January 13, 2018, 4:41pm

I have dual 6374s 170KV motor from APS, my eRPM limit was left at 60000.

could be a simple silicone lottory faliure. hope you get this sorted. feels bad man.

SpeedyGonzales · January 13, 2018, 5:06pm

It looks like you were well within limits. That sucks.

banjaxxed · January 13, 2018, 5:48pm

Vesc 6k limit is 150k…could it be a reason elsewhere?

Eboosted · January 13, 2018, 5:55pm

I switched to BLDC mode, no more cutouts, evetything working perfect. Miss FOC a little bit just for launches.

Stewii sent me some procedures to pinpoint the issue but I still need to find time to open up the enclosure

bimmer · January 14, 2018, 7:14am

Just finished my first one… some parts didnt come so I borrowed them from an old vesc…while flashing the firmware there was smoke…sigh I’ll report back when my 2. iteration of parts arrives…

SOICDIP · January 14, 2018, 7:36am

Can you get a closeup of the DRV?

bimmer · January 14, 2018, 7:37am

I just did that to the drv.

scepterr · January 14, 2018, 8:21am

Is that flux or solder? It should really be cleaned up to properly inspect, solder balls floating around

And what’s going on here

bimmer · January 14, 2018, 10:02am

To be honest this is the first smd soldering I’ve ever done. So its learning by doing so this was a 80$ lesson so far…

stewii · January 14, 2018, 9:06pm

I have an inrunner 5000kv and tested it with a 3S battery (specs says 2S max) and got about 100k erpm. Here is a printscreen, top is BLDC and bottom FOC.

banjaxxed · January 14, 2018, 9:14pm

That will buff right out
