hi im using a flipsky 75200 pro v2 on a ebike with hub motor. running 16s batt at 250 phase amps. under acceleration i am getting a pulsation around maybe 15-20mph on the way up to the top speed of 40mph. it occurs for about 2-3 seconds. its not severe and i dont notice any change in how much it accelerates. its not bucking or cogging. its kind of a high frequency vibration i can feel through motor/frame. but basically it doesnt feel like its going to break anything and i could live with it if i cant change it. i am just wondering if anyone else has had this issue or if there was a setting they changed to address it. i am on the stock firmware it came with labeled 75_300_r2 version 6.02. i am aware of the flipsky 75x00 firmware issues, but have read the pro v2s should be left alone as they have some changes. i have tried casainhos bin file as well for 75200alu with no noticeable difference https://github.com/casainho/bldc/releases/tag/fix_noisy_currents-firmwar... i can include pics of my current settings but i dont know how to attach pictures here. -edit nvm found it
Did you sort this mate? I'm having a very similar issue. It kind of feels like resistance vibration. Like an extremely light cogging. Still gets up to 40mph on 48v 120a phase and accelerates hard but around the same speeds, give or take a couple mph, I get that drdrdrdrdrdrdrdrdrdr then it goes away.
Phase timing mid duty maybe?
Someone help 😂😂
I had a similar problem. What I did to fix it was I changed the senseless rpm setting to faster then my motor would even go. Mine was changing from hall sensor to senseless mode at set RPM, and I guess it didn't know where it was at. So it was chugging/ pulsating for a bit. Similar to if you run sensor less mode on BLDC. Right at the start it will chug.
