FLIPSKY new 20s 100A tiny controller (vesc based)

[Ianhill]

I think all Vesc based esc can do regen


This one has shown much better in many ways. https://flipsky.net/collections/electronic-products/products/flipsky-75100-with-aluminum-case-based-on-vesc-for-electric-skateboard-scooter-ebike-speed-controller

The 100amp runs hotter than the 200amp version i dont see it as better its near the same footprint but half the power with more heat how they managed that one is impressive, the 72200 runs 20s 100 amp max as the volts drop the amps can rise so 48v can run 200amp its a 10kw controller.

Anyone know how tight the 84V parameter is? I am hoping to run a 72V nominal LiFePO4 (24s) which charges to 87.6V

I meant in relation to the others mentioned here and in the title. Yea not that one.

I had the same question and was told the bits on it are all rated to 100v. Others I know are doing 83v. I’ll be doing the same as u: 24s lifepo4. At least with the aluminum pcb 75100

I guess we will find out

I guess we will find out

Flipsky shows a short data log session with the 72200 on 48v 72v and 84v vs a few other of their controllers.

Take a look at flipskys vid on youtube the 72200 heats faster at 84v but from what i can tell all the runs equal around 10kw.

Ive tested mine on a bench with a psu set to 84v 15amp so ive not load tested it to test heat output but i wouldn't expect consistently high figures in warm climates without swaping the heatsink or adding a fan etc.

I'm not too concerned about heat. I already planned to improve the heatsink and add potting to help with vibration. Going to look the whole board over as well.

My main concern is about the max voltage. If 84v is the absolute max with very little headroom for spikes, I am just worried that 87.6v might just push it over the edge and fry the capacitors or something. I already bought it with the intent to try but I wanted to see if anyone else had tried before I let the magic smoke out.

I wasn't sure if they could do variable regen with an analog input. Thanks.

Then again maybe I don’t know what ur talking about. I think all the Vesc variants will do regen, I don’t know if “variable regen” with “analog” is something else


Where’s the vid comparing different Vesc and voltages done by flipsky.

Adc2 supports varible regen in setup i think its called current brake no reverse or something like that.

Or u can run “current brake w reverse” and still do regen braking and go in reverse (for those who like to do party tricks at stoplights)

Thanks for the video and great stuff. The 75100 got hot pretty much as quickly as the 75200 in the test using 100amps. Nice to see. The temp data changes very quickly in response to the current or lack of current.


I have a fundamental lack of understanding on the power output from the esc and motor: A x V is power so can I get more power from the esc and motor with higher voltage as it’s the amps that are creating all or at least the large part of the heat?

1.10 on the vid flipskys own words.
From what i can see the 48v 200amp test takes longer for the fets to warm vs 84v 100amp test so id say the heat is from the fets worlimg on the outer boundary of their spec but ive not got the data sheet for them.

The controllers over a mates house and im off over there later so ill try and get the fets datasheet if they not removed the identity of them.

They say the 200 is better than the 100 at keeping down heat and would make sense but the test doesn’t show it. In fact seems a bit more delay in the temp change registering with the 200 and it doesn’t drop as fast when the current stops as the 100..but then again the 200 is starting at 55c not 45c so not a fair comparison

I asked them about why 10kw limiting and they mentiines the test equipment but the vesc itself is logging so i can only imagine the psu they use is tapping out at 84v 120 amp.

As for the heating ill have a good look at the vid on tv in a bit see if i can observe your point.

How u do this?

I look forward to seeing the Vesc temp sensor data after waterproofing and running water over it. What gets hot and needs to be cooled? Fets and the big caps?

hi
What is the torque of the 75100 controller at 0 rpm?
How is the acceleration performance from 0 km/h to 15 km/h?

full torque, full power hardstarts is it possible?

Does the work well with golden motor magic pie 5, has anyone tried it?

The magic pie 5 internal controller had super torque at 0 rpm, the throttle response was very good. it malfunctioned.
I don't want to buy the same internal controller again, because it has limited features. (1000watt,45km/h,48volt)

but I didn't know how to change it. I tried two cheap Chinese controllers, they were very mediocre. I fell into despair.

I got hopeful when I read about FOC on the forums.

but the problem is that forum users are usually interested in high power like 3-10kw.For this reason, hard starting at low speeds such as 0-15 km / h, high torque is of no interest to anyone.because at 3kw-10kw the starts need to be soft.That's why I couldn't read enough information on the forum.

I am looking for a controller with 1.5kw-2.5kw,16s,hard start,throttle response fast.

The 75100 controller does not have a phase filter.I've read that the phase filter is related to better performance at low rpm.phase filter is required for hard starting?

In my experience and from what I have read elsewhere that is the biggest flaw of the 75100. It's a VERY soft start. That's fine for electric skateboards but it's not great for ebikes. Unless someone else has found a way to make them start strong...in my experience running 72v 100a battery and 120a phase (maximum power) produces a lot of heat but accelerates slower than a 16a geared hub ebike

thank your reply ,Isn't Foc supposed to be good at low revs by definition?
how is the low rpm performance on other vesc hardware?
For fast hard start am i looking in the wrong place?

I don't think it is the FOC aspect. At low speed the voltage is very low and the controller can only put out 100a so let's say from a start you pull 100a at 2v...that's only 200w. Other controllers, even cheap Chinese no name controllers, can put out much higher amperage for a few seconds to get you moving from a stop.

This is my understanding from my reading on the topic and what I see on my data logs for the 75100. I am not an expert. I hope someone else can chime in and confirm or question my explanation. Id love to make my controller accelerate better so I hope I am wrong! Haha

The highest torque can theoretically be achieved at low rpm (difficult to implement)because bemf is low

I should note that at low revs you want TORQUE.
Yes, higher amps equal higher torques.

However, amps means heat losses squared. When a typical cheap controller pulls a kilowatt of power from a stop, only a tiny amount is actually converted to work.
The rest is dissipated as heat in the motor and controller.

Well from a stop the best I can get out of this 75100 is 200w which makes it a childrens toy unfortunately. Again maybe someone else with experience can chime in with a different experience. For me it seems like these have very little utility for an ebike or anything larger than a push scooter.

I played with it some more and I have gotten more torque out of it. It also goes 50 before over heating and it seems like it has more in it without field weakening tweeking. I may just have too tall of a gear on it.

Regardless the heat is problem. It's only good for a 10 second burst at 120a before it goes into thermal throttle. Going to try a 75200 next. Seems like it will be way better in terms of heat just based on the weight and amount of aluminum but we will see.

Curious if there was any specific changes you made that helped.

Out of desperation I tried using the motor config wizard like you are supposed to but I did it with the chain and wheel attached. When I do this the damn thing goes from throwing all sorts of hall sensor errors and others to detecting everything just fine. I am sure my values are wrong but it works and I got it up to 50mph before the controller overheated. I am hoping my new 75200 will give it more low end grunt and also reduce the overheating. Fingers crossed. I should have the new controller installed tomorrow.

When the day comes that the my1020 dies I will probably ditch that style of motor some something else. It's been more hassle than it's worth.

 

[Braddudya]

Update: the 75200 controller is a VASTLY better controller in terms of bike sized use. It made the Pitbike rip and accelerate smooth from a stop with zero tuning as of yet. I did still have to run the motor config with the chain and wheel attached for some reason but the bike screams now! With the 75100 set to 100a I could do one run across our warehouse parking lot and it would already be thermal throttling. With the 75200 set to 150a I was able to do 10 runs back and forth and it was only a bit warm to the touch. I couldn't get the Bluetooth connected for some reason yet so I don't have hard numbers but it seems to have solved the heat issue.

For anyone considering a mild scooter drive or a mild eskateboard the 75100 might be great set to 60 phase amps. If you want to run a bike get the 75200 or the 75300.
