Hi
Is it possible to connect the phase wires of two vescs in parallel to run a single larger motor? The application is a boat so no regen or braking needed just power.
Can anybody tell me what i should do to make them syncronized. I have a Vesc 6.0 from boundmotor and im using vesc tool 1.29
I'm trying to use a VESC 6.0 board in a slightly different application.
I'm trying to build a gasoline/ electric hybrid. Is there a way to set the throttle curve based on time? Something like 0-100% throttle functions normally for the first 10 seconds, then tapers off down to a 0-(-5)% or so for a regen based on battery charge voltage?
Basically think of it as I want the BLDC motor to function as a boost for 10 seconds every time the throttle is applied from 0%, then taper back off to charge the battery pack from the Gasoline power plant.
Hi,
I have been reading about protecting mosfets for 100V designs - and I am a bit confused,
different app notes have different suggestions and I am not sure as to the purpose for all of them,
I am looking to create a high reliability design - the one that should not fail, what are the protection mechanisms that I can put in place? - essentially asking how to design the power stage.
Here is what I have so far:
Hi!
I wanted to isolate (optically ?) the VESC control board from the power board, since I plan on working at 300V DC, and here is what I have so far:
- Digital and PWM signals go through: A4506 opto isolator (HCPL-4506)
- Current sense through ACS series (712/758 - depending on current requirements of the design)
Hallo all,
How to select in VESC Tool the COM port of PC for USB connection to VESC6?
Menu connection: Port "COM1" is the only port shown. Clicking button "refresh serial port list" results in nothing new, only COM1.
The last working connection was shown as COM6, but after successful running motor wizzard the tool lost connection when I tried to select the control input. (Should be ADC, wired potentiometer.)

Hi,
I understand that when moving from 4.12 to 6, the current sensing method was changed from 2 shunt 'bottom side' to 3 shunt 'in phase' .
Current sensors for in phase applications - specially for high voltage application are pretty expensive, and the only credible option for me seems to be the ACS758 or variants that other members seem to be using.
Questions:
- Is there any benefit of 3 shunt 'in phase' sensing over 3 shunt 'bottom side' current sensing for FOC ?

Hi
I' am having doubt's regarding which rotor position estimation method should be used for a 1 Kw surface mount PMSM. Is it possible to use signal injection method for finding the rotor position?
Thanks in advance,
