Re: 24FET 4110 Controller Modified Lyen MII Edition
Bet that thing hammers.
I have not kept up over the years but I think a lot of folks are moving toward smaller controllers with more advanced functionality. Lets see...
https://www.ebikes.ca/shop/electricbic ... llers.html
Hmmm...
Skimming I see a lot of words like "Waterproof" and "Field Orientation"
...
Something like this 24 fet for sale is a different sort of deal. If you want wicked bruit force out of a big low KV motor then this is the way to do it. Run a hundred volts with a 100A limit on Low KV... and you will literally bend metal.
Most folks are just looking to ride smooth. .. .....
I would pay a few hundred bucks for a big bulky controller.
Most people wont any more because they can get reasonable power out of a very tiny package.
Not the same tho...
Always a place for the "Big Block"

Increasing battery voltage and controller current limit will result in a non linear experience
Re: 24FET 4110 Controller Modified Lyen MII Edition
Quick question, just for youmethods wrote:Bet that thing hammers.
Context: heavy cargo/tandem say 400+lb gross, in Utah and Colorado type mountain landscapes, so maximum torque is needed. Speed is not at all important, figure at 1012mph going up hill, 25mph max speed on the flats. Range efficiency, miles per kWh is **critical**
Call it 100 battery amps available for short times, usual longer stretches say 60A max. CAv3 to be used for overtemp throttling.
Question: from my reading, I thought 4854V was as high a voltage as I wanted to go, then I came across this quote in my past notes:
> The 72v ecosystem is better for going above 2500w
Is that true, even when speeds will not get past say 2025mph?
In other words:
Is there a (class of) motor out there  that **requires** voltage over the 5254V range  that is so compelling, delivering robust reliable superhigh power / torque at **low** speeds, that makes it worth the hassle going to 60+V or even 72V?
Fat wiring, no problem.
Flippy says "more volts = always better"
Ed Lyen says
Related threadsFor the best power to efficiency ratio at 25mph or less (especially if torque is the priority), the recommended voltage is around 4852V.
The reason is that the controller's MOSFETs do not need to work as hard (by minimizing the need to switch on and off internally). Therefore, there will be less wasted heat produced.
In addition, the throttle characteristic is more linear, when compared with using a 72V system, which is critical for the hill climb.
The only reason to use 72V or higher, is if speed is the priority and/or if the existing wiring on your ebike setup is on the thin or skinny side. The power (in wattage) on the smaller wire(s) can be compensated with higher voltage.

Re: 24FET 4110 Controller Modified Lyen MII Edition
You have Motor Reliability
You have Controller Reliability
If you want to create Torque then the first thing to consider is Gear Ratio.
This means wheel diameter and KV of motor and Voltage
You need all 3 to make a statement
The second thing to think about is Squared Losses
Current Squared = Heat
Speed Squared = Friction
So if you are going slow wind is not your enemy.... but you are cutting flux slowly....
In this case, in my opinion, you want lots of poles and lots of voltage
TICK
TICK
TICK
Unless you have advanced algorithms (here we are talking about leveraging a STANDARD trap ebike controller)
In that case you want to minimize your wheel diamter
Minimize your KV
Maximize your voltage
Mosfets in a controller produce heat by the current squared times the ON resistance.
The more you switch on and off, the more you are hitting suboptimal ON resistance
But ... below some point... that is linear
What is a much larger factor is the Current Squared
High Voltage has other drawbacks... Which we can look at in other ways... but when it comes to transferring power.. specifically switching power...
You can switch current
You can switch voltage
Which fails first and in what way?
...
Switching current is NEVER GOOD
Current does not want to change
Switching voltage just requires understanding of drawbacks
So..
If I wanted to go up hill all day every day with high reliability
1) Smaller diameter wheel
2) Lower KV motor
3) Higher voltage battery pack
It is BOGGING that overheats motors. . .
It is BOGGING that pops controllers...
Same as Ping in an internal combustion engine
... hmmm... other ways to say it...
Go get your Ryobi Drill
Set it to #2 high speed setting
Stall it out
Over and over and over
Get a new drill
set it to #1 high torque setting
Stall it out
Over and over and over
What it boils down to is having an appropriate amount of torque on hand to get the job that needs doing done. There is no sense in making edict about some random battery voltage (in absence of KV or wheel diamter). It makes no sense to make a statement about a given motor KV (in absence of excitation Voltage and Current) ... and... we all know that smaller wheels make more torque and result in less bogging....
...
Get a 6 fet controller
Populate it with the best fets you can find
Run it at FULL THROTTLE for 20 minutes
Run it at 20% Throttle for 20 minutes
Report back
Get 2 hub motors
One low KV
One high KV
Lace them both into 26" wheel
Run them both at a Constant Current, at a Constant Voltage, and at a Constant Power
From that you will find the truth of interdependent variables
... Altho flippy annoys me (not sure why, he sounds like Luke in disguise, I know Lukes voice) he is right if he said that high voltage is always better.
To a degree...
To prove that:
Get 2pcs 6fet controller
Configure them to run 2000W each
Run one at 24V and whatever current it takes
Run one at 100V and whatever current it takes
Run whatever mosfets you have to
Which one failed?
Which one lived?
(of course to do that test... you must have a fair test in place... which means DIFFERENT MOTORS of DIFFERENT KV... so DIFFERENT LOADS)
IF
We are to say that one battery voltage works better than another...
IF
We are saying that is true for a specific KV+diamter
Fine
Otherwise 
Takes 3 formulas to solve a 3 variable equation
Ok bye

Re: 24FET 4110 Controller Modified Lyen MII Edition
Yes from a practical POV, for efficiently pushing heavy weight up long steep hills, I concede gearing external from the motor will be needed.methods wrote:If you want to create Torque then the first thing to consider is Gear Ratio.
But for my foundational 101learning about these issues, positing DD.
Reducing wheel size is limited by rough terrain + no suspension, fatty tires compensating a bit but I think a decent wheel diameter is a given, even if using motorcycle/moped type tires.
Kv will be low to favor torque over top speed.
I want voltage to be 52, 14S LI, unless **really compelling** reason to go higher, if that really does gets me
1. more torque at lower speed
2. less heat at given torque level
3. greater energy efficiency, kW/km
then I'll concede and go to 20S 72V
A sine wave / FOC controller is fine if that makes the difference? not sure why square wave / trap is assumed?

If I were not a broke hobo. . . I would buy that thing right now.
Nothing like a big beefyass controller!
mmm... Torque
... I do see tho that advancements in technology have created a new set of controllers that are so much more compact.

These days I really am not in the business of Test so much as Practicality...
