Hi,
Could somebody say me at which frequency is called this function : mcpwm_foc_adc_int_handler on a 75_300 board
Thanks in advance,
Hi guys, I'm sorry if I'm off topic you can delete the post if it not useful for the community. I want to ask a stupid question from a noob like me.
If I have a brush DC motor, in my case a MY1020 500W, is it possible to increase torque of the motor, in particular stall and low rpm torque (high RPM are useless in my application), replace the magnets with a greater number of it and with a strong performance material like neodymium?
I think that now are in ferrite. The number of teeth in the motor are twenty and magnets are four.
Hello,
My motor is used to make sometime big regen.
My battery owns a BMS and as a result, I absolutely need to take care to not make the BMS trips, otherwise I will burn the VESC (because braking with battery disconnected generates overvoltage).
How to prevent regenerating if battery voltage is too high ? Example : the BMS will trip at 42,5V. To get a safety margin, I want the VESC not doing regen if voltage is greater than 41,5V.But I want to be able to discharge.
1) How to implement this behaviour ?
I'm working on a dual-VESC balancing project. Is it practical to connect an external IMU to one VESC (running the Balance app) and a Bluetooth dongle from the other one and then tune the Balance app wirelessly via the CAN connection between the VESCs?
I am looking for examples of heavy applications and experience thereof, +200kg vehicle, 15-25kW output. A controller such as a VESC 100/250 seems to be cabable of great things but I have a hard time finding heavy applications. Please advice or link if you know of any, thanks a bunch.
Hi All,
My first post.. First VESC, too. I've hooked my Flipsky 75100 to my computer (and battery and motor), and downloaded VESC Tool. When I try to autoconnect, I am told "Could not autoconnect. Make sure that the USB cable is plugged in and that the VESC is powered." My baud rate is set to 115200.. What am I doing incorrectly?
Hi guys. I'm new here :-)
I'm about to integrate a VESC in my scooter conversion project.
For material protection and safety, I'd like to disable the throttle while braking.
Is there such an interface and function in the VESC 100/250?
Thx for your help.
Best

planning to use a regular ebike throttle (hall). Do I connect it to the comm port - ground, ADC1 & VCC (is the vcc 3,3v?)?
the bluetooth module is connected also to the comm port via Tx, Rx, ground & 5v? that means the throttle & bluetooth module share ground. is this OK?
Hi,
Today for the second time I burned a maytech 75_300 with:
12S liions
Motor Hacker Q80 8M 8m
drived via pwm
freq at 50Khz or 60KHz
Ctrl : pid speed no reverse
Current limits set to +-160A
erpm final consign at 100360erpm
no breaking
the pwm from my autopilot increase from low duty to high duty cycle in on step, i'm using a 40 seconds rise up inside the pwm app to have a smooth ramp.
