Third Party Hardware

I was not able to find an acceptable solution for electric sailboat. The use case is unique and I found most sellers provide preexisting off the shelf motor solutions adapted poorly to the use case or engineered solutions not properly addressing the real world need. The solution if it existed would be 95% power generator and only 5% motor usage. I am not an electronics engineer but a software engineer, I do have some knowledge about BLDC inner workings from experience.

Hi guys ive got a vesc 6.6 that has a faulty stm32f405 and a faulty drv8301 chip. Im looking to purchase a replacement drv8301 but there are x2 options i can find. DRV8301DCA or DRV8301DCAR i cant work out what the differences between the dca and dcar are so i thourght id chime in here and ask the question. 

Hi everyone I'm using a Maytech SUPERFOC 6.8 with a 24V 15A PSU, and I'm using it to operate a bldc blower in FOC mode with hall sensor (auto recognition of FOC parameters ok).

The VESC responds well up to 60K ERPM - 90/93% Duty cycle approximately, and after the VESC shuts down the motor completely without signaling any failure.

To restart the motor I must press the stop button, set the PPM to idle and then raise it again.

The motor never exceeds the set current or others limits.

The firmware is the last available in the VESC TOOL.

hi guys,

i have FSESC V4.12 for 4 months and it was working great in combination with VX1 remote controller. VX1 receiver has VIN sens wire that is connected directly to positive lead of the battery for battery information on remote. so, today that pin came loose from receiver and touched 5v pin of CAN connector and now vesc wont turn on and now 5v rail is shorted the ground. ive checked only TVS diod and it look like its shorted too. 

**UPDATED SUMMARY**

v0.9 released on GitHub. Beta testing ongoing with success so far.

I have a 3rd party vesc and i went into the vesc software. i connected it within the software and it said i needed to update the firmware and hardware. i did this anf then tried to use my vesc after. i did all the correct things waited a while before unplugging. the vesc now skimpily wont work and the software wont allow me to change the vesc back to it original firmware and hardware. does anyone have any solutions on how to go back to hardware 4.12. thank you. 

What about using the votol em150 3kw 48-72v electric motor controller programmable?

Hi, 

we use a vesc 4.12 (newest firmware) with a big outrunner, driven by a 200 cc honda clone engine to first start the engine and then to generate electricity.           





the motor/generator is rated at 5kw and has 27 poles, kv number is not know, its supposed to charge a 24v battery with the engine running 3-3.5k RPM.

Hi fellow eskaters.

I need ur help, unfortunately i didnt isolate vx1 receiver module properly and voltage sense pin which is connected to battery positive touched negative lead and few smd components were fried. 

Can u please measure and write values of selected components from image with numbers as id thanks

Please let me know if this information exists elsewhere, thanks!

Target Motor: Pump; 3000-6000 RPM@70V,10A max - to run directly off Solar panels

I am aiming for a BOM cost of $40 for the VESC, and have selected the following components for a 100V-20A build
