optimizing the set up to reduce mosfet heating

Submitted by tromes on Tue, 2020-06-16 02:48

I am using a Trampa Vesc 6.4  for an efoil with a 12S battery. The vesc is rated 80Amp continuous and the motor detection wizard gave me 100 amp, so that vesc 6.4 seems to match pretty well the set up.

The motor is supposed to be rated at 150A/50V so about 7.5kW, but I am happy to use it at a max of 4kW.

I have program the Vesc with the motor wizard detection as FOC using a PWM signal in current no reverse mode.

Hi,

 

i got my brand new VESC and downloaded the new VESC Tool (2.06) to my Computer.

I succesfully connect with USB and got soon the Information that i have installed the Firmware 4.2, it is good and proofed blah blah.

When i want uptate read the Realeasenotes. I do that.

When i go to the Firmware part i only see the Version 4.2.

I can see in the COnnectionstatus line: Connected on COM3 in limited mode.

 

What is that?

What do I need  to check?

Thanks. 

Setting up a VESC 6 MK IV and need 58.2 voltage fault

Submitted by warrenhdavis on Fri, 2020-05-22 07:34

I am setting up with an Ebike Bafang 750W 5-1 Geared Hub motor. Running 2000 watts max. I am not using any regen braking so no voltage spikes are going to come in. The problem I have is when my 14S 13AH battery comes off charge it's right at 58.1V. This triggers the 57V alarm. Is there any way to raise this 57V fault upper limit without re-compiling the firmware? 

VESC 6, astroflight 3215, loosing sync with freewheel

Hello,

 

  • I have a mountainbike with a astroflight 3215 connected to the rear wheel with a 2 stage reduction. On the intermediate shaft I have a freewheel, the ratio from the motor to this shaft is 4:1.
  • Battery is 12s.
  • motor kv is 169
  • Phase current set to 60 A
  • throttle controls duty cycle

 

The motor wizard did a good job and the combination works great, except for one big problem. 

Problem:
