Maytech ESC and VESC doesn’t have fan, has reverse and regenerative brake.įAQ10: Do I need to connect VESC signal cable if I do not use remote control?

#VESC BLDC TOOL DOWNLOAD#

Please noted: This VESC firmware is with parameters, you can write parameters from a good USB port and copy the firmware out, then use STLink to download to VESC with bad USB.įAQ9: Does Maytech VESC has fan, reverse and regenerative brake?

Choose 19200 transmission speed in VESC_TOOL, choose virtual port of USB convery to TTL convertor.

Open UART in VESC with good USB port, write transmission speed value 19200, copy the firmware and download to VESC with bad USB port.

Can’t use default firmware because UART is not opened.

Choose suitable port in VESC_TOOL, choose specific speed rate and connect.

Use TTL cable on side of USB convert to TTL to cross connect with TX and RX.

#VESC BLDC TOOL SERIAL#

Computer will show virtual serial port after driven download finished.

Use USB convert to TTL converter connect to computer, download driver.

Download firmware that has UART port opened and get in.

#VESC BLDC TOOL HOW TO#

If you use STLink USB to upgrade, then VESC will with boatloader automatically.įAQ8: How to use UART Port to adjust VESC parameters?

VESC firmware without boatloader, STLink USB with.If you use VESC_TOOL, then boatloader in VESC firmware will be vanished, need to use STLink USB to upgrade. VESC firmware with boatloader, VESC_TOOL without.

#VESC BLDC TOOL UPGRADE#

If VESC firmware already with boatloader, then can upgrade in VESC_TOOL directly If VESC firmware is not with boarloader, then need to use STLink USB to upgrade.

ESC can automatically detect 3 cables phase sequence, need to adjust mannually, total 6 phase sequence.įAQ7: About VESC Boatloader and STLink USB?Īll our VESCs default firmware are with boarloader.

VESC has 2 methods to adjust motor direction:Ĭhange random 2 cables connection and detect.

If use sensored motor, can detect phase sequence in VESC_TOOL automatically.

If motor direction is not correct, just need to change random 2 cables connection and detect.

If use sensorless motor, don’t need to adjust phase sequence, 3 cables can be connected randomly.

So in VESC-6, the decisison was made to allow the hardware to measure all three currents, and to not-use the one predicted to be least accurate and then calculate it from the other two.įAQ6: What is the difference between ESC and VESC?

Due to imperfections in real life, some of the measurements are more accurate than the others.

Has great FOC function, quite, low consumption.

So the first VESC (VESC-4) was built when TI recommended measuring just two of the currents and calculating the third if you needed it

The same holds for a motor with three leads: measure two and you know the third.

Do not suggest to use FOC function, can only use under low voltage (3-4S).This means that when you measure one you know the other! So a battery delivering 1A has 1A going into the device through the - pole and -1A going into the positive pole (i.e. It is related to electrical rule that the sum of the currents going into a device is always precisely zero. VESC6.0 is improvement hardware over VESC4.0. Energy feedback brake, faster retarding brake.įAQ5: What is the difference between VESC4.0 and VESC6.0 hardware? Vector control, sinusoidal driven, small torque ripple and quite.Ĭ. VESC6.0 hardware has FOC function, it has the below advantages:Ī: Automatically recycle energy when decelerate, lower consumption, higher efficiency.ī.

#VESC BLDC TOOL DRIVER#

SUPERFOC6.8 has great FOC function, it use better quality driver chip DRV8301, which can fix the problem of DRV error that always happens to VESC4.0 based controller.įor VESC4.0 based controller, do not suggest to use FOC mode, even if use, can only run in low voltage mode, like 3-4S, otherwise may cause DRV error under high voltage.įAQ4: What is the advantage of FOC function? VESC50A is based on VESC4.0 hardware, SUPERFOC6.8 is based on VESC6.0 hardware.Ģ. If you use VESC without hall sensor, can adjust random 2 phase wire connection, then detect.įAQ3: What is the difference between Maytech VESC50A and SUPERFOC6.8?ġ. If your controller is with hall sensor, need to adjust 3pcs motor cables and controller cables phase sequence and detect, find suitable connection.Ģ. FAQ1: How to detect motor hall sensor in VESC_TOOL?ġ.
