HESC V1 150v 600Amp VESC based motor controller

[eee291]

At first, it seemed up to the task for my small EV with a Motenergy ME1012, based on the initial specs.
After looking at the size and wiring thickness, it seems to be better suited for my Diesel Hybrid car.
I will mount a Hyundai hybrid generator on it. Eventually.

Nothing is certain yet, because my biggest issue is that the VESC doesn't have any 12V tolerable inputs.
I would need an ADC of some sort to connect reverse, brake etc.

It doesn't even have a digital input for the reverse, I suppose it requires an external board to send it with the UART.

I could be interested at the C700 to replace a sevcon that has not enough motor current for my ATV with a Motenergy, but it requires a lot of integration work (contactor, brake, reverse, eco/boost mode, 12v hall sensors, ...)

 

[eee291]

Reading vesc Forums online, it looks like you can pull RX and TX pins to ground for reverse and cruise control.

I'll have to test this. But I think I also found a suitable ADC with 12V inputs, but it'll take a while.

You could go the voltage divider / zener routes too.

@eee291: how the 3shul working for you

 

[eee291]

It has no water or moisture proofing of any kind, so I won't use it on my bike.
I have it set up on a table and will do a sensorless test over the weekend.
After that, I'll look into moisture proofing at least.

@eee291: I would be very interested in your testing and water proofing results. Thx

Please keep us posted.

I have the CL700 and hackey told me it was waterproof.

 

[eee291]

That's nice.
This is what the CL350 looks like.
A 3d printed lid held together with some machine screws.
Maybe it'll get a nicer cover some day.

Some silicone adhesive around battery/phase ports probably work

 

[amberwolf]

I see at least two other places (a slot on the "top" and the gap around the signals connector, as well as all the signals pins of the connector) that would easily allow significant water intrusion under the wrong conditions.

The screw holes themselves (that hold the two case parts together) may need o-ring seals, depending on the flatness of the base of the screw heads and the machined faces relative to each other.

May also need a seal between the case halves for the same purpose.

Here is a little test in sensorless mode because the motor has no halls.

About the waterproofing, since I won't use it on a bike I was thinking it would be fairly safe from water inside a lawn tractor.
That was my initial plan anyways.

I think I'll get the CL700 for my car.

In a car you would not want a sensorless system that has equal chances of going backwards as forwards when it begins to get rotor motion. That's a crude sensorless. A good FOC setup will not go backwards for a rotor tooth before it goes forwards.

 

[eee291]

I only used sensorless mode because this test motor had a resolver.
I'll try adding some sensors to this motor if I can get it apart without damaging the cooling jacket.
The car has a ME1012 motor in it with hall sensors, so no worries there

I rewired it to delta and used field weakening. I had to cap it at 12.5k erpm because above 13k it would come to a sudden stop. No load current pretty much doubled.

Before it did 4k erpm and about 9k with fw before it stopped.

I like it much better now time to put it in something.

Is that a Hyundai / Kia hsg?

Yup. It has the best price/kw ratio that I can find right now.

Cool. Do you have a write-up / reference on how you did the delta mod on the hsg?

It's fairly easy, probably a good idea to change the 2 o-rings or check if its water tight at least.

The HESC is still on my radar but I'm a complete VESC noob. Can the HESC/3shul be used with a generic speedometer that works off a hall signal like many non-vesc type controllers? Also, what about attaching a 3 speed switch to control power/speed?

 

[eee291]

This is my first vesc based controller, it's not difficult to set it up at all. It can use Halls, encoder, sensorless etc.
There are profiles you can create and choose via the app, I haven't figured out a way to do this analog.
It may be possible via uart or something like that.
There aren't many analog pins, there is only throttle, var. regen, reverse and cruise control.

I received my CL350.
Unfortunately the 3shul motors site is down for maintenance,
Is someone have the pinout.
Unfortunately, I did not downloaded the manual before.

Thanks

If you have their Bluetooth module you may have to use the 5v output not 3.3v

Thank you very much !
