Hello everyone, help me define the current settings for inverter.
I have an inverter und made a "VESC" processor.
The inverter has a DRV8323, three shunt resistance 0.001R - 5W.

#define CURRENT_AMP_GAIN ????

Good morning Boys, i already asked in general forum, but i didn t recive any information, maybe It was in a wrong section.
I changed the old esc with a new vesc board in mu ebike. The battery Is a 16s10p 26000mah.
So my problem Is that i don t have torque when i push the Throttle. The maximum velocity Is the same that i had with the old esc . The old esc was a 60v and 40 amps. The new esc Is 72v 130 amps in continuos .
The motor Is a 1300w continuos Power and 1800w peack Power 60v sensorless.
I have installed R2 and the Hyper-V component, virtualization is enabled in the BIOS. My problem is there is no "New" option in the Action Pane of the Hyper-V Manager.
My version of R2 Enterprise installed is 64 bit and off the disk that comes with the MCITP Server 2008 Enterprise Core Training Kit put out by Microsoft. My laptop is an HP dv7-3085dx
Hello,
I am new to VESC and bought a Flipsky 4.2 to drive my custom motor. The motor measured phase to phase inductance is 16 uH and resistance is 170 mohm. I read in some forums that this inductance (only 8 uH phase to neutral) might be too low and cause very high ripple currents. Is this a problem? Some forums recommend to add a series inductor on each phase in the order of 100 uH or increasing the PWM frequency to the order of 100 KHz. Have anyone used the Flipsky 4.2 (or 4.12) with a similar very low inductance motors? If so, any issues? Thanks!!
Howdy.
I'm working on a project to create electric roller skis: two skis (no wires between them) and one remote.
Hello,
Hi
I have 2x Maytech SUPERFOC6.8 50A, and I’m playing with the idea of testing how much burst amp I can get out of them at different temperatures. I know I could just buy bigger controllers, but this is purely for fun and finding the limit of the units :)
My thought was mounting a copper block to the mosfet case on both sides and cooling this block with a peltier element. The hot side would be cooled by a CPU cooling block and a fan.
I am aware this is super inefficient and will drain the battery fast.
Hello Friends,
Talk about stumbling at the first hurdle.
I am trying to setup my Maytech MTVESC6.12 controller but I am unable to even get it recognized by Windows (10) or VESC tool. There has also been some funny behavior from the controller. So in approximate chronological order here is what has happened:
Hi All,
I almost finish my custom esc derived from 6.6 MkIV hardware , DiabloEsc, I did it because I need a round pcb and I dont need external connectors like hall effect , uart servo etc.. just Can Bus, NTC and Power Supply, the only change in schematic is BMI160 Imu instead of MPU chip.
I'm not familiar with STM32 world and I would like a starting point on how to flash the newborn board firmware once assembled.
