Note: Please don’t exceed the range, which will cause demagnetization and damage motor.
Is it possible to damage my electric motor?
Yes, the field can demagnetize your magnets if it is too strong. Keep within limits.
If you raise voltage you'll get proportionally higher speed. The motor will be fine.
Controller can be damaged if you have a 72V controller. 96V is probably too high for the mosfets and caps to have any safety margin

To control which I bought and wait is for 96 volts.
Of course I will drive at no more than 45 amps, but I will also do 70-80 amps for a sport mod which will be limited within 30 seconds

I tried setting current at 200A DC on the new EM72150SP - measured output is about 200A. -->Controller is still unlocked in the new version.

I wonder if they changed to cheaper mosfets as the rating was reduced so much or if they had a lot of controllers break at 180A continuous output.

What do you mean? Are these controllers locked and in what sense?

normal controllers are locked so that you cannot exceed max amps. These are unlocked, current can be set above rating but with increased risk for failed mosfets. I want to highlight that it is not fair to seek warranty returns from QS if it happens above rating :flame:

I consider the controller function to be my responsibility when doing this.

The new controller has arrived.
However, I have a few things.
Problems:
The first is that the program always recognizes it as EM50 and 72 volts after the controller is at 96 volts.
When I make the connection to the controller do I have to change it every time before writing anything to the controller.
The second is that the outdoor temperature sensor shows -10 degrees constantly. It is most likely damaged by a colleague's external intervention. when he placed cables to connect to an analyzer.
Fourth: The engine is a little noisier. A high frequency sound is heard when moving at higher speeds and at acceleration.
Third: Large sizes.
Fifth: Noho I put value in the fourth page (picture 1) after the refresh program does not read the values ​​to me and shows me that they are empty and not used but in practice

Negatives: None

Positives:
Mota does very well with this controller.
100 amps is 100 amps. It feels .
And I set a maximum of 75 amps and the bike will fly out.
Very good. With the change in flux weakening, I curtailed a maximum speed of 60km under normal operating conditions, on a level street and 130kg above.
I weigh as much as two people.
Good acceleration. Everything else for now is great except for the problems described above.


Discovery:
So far I have found that the values ​​from the fourth page of the program (cardboard 1) are for program combinations, not as I thought they were for the pin outputs of the controller.
These are separate commands to the controller what and when to activate.
This is the original combination of my old controller and all new values are empty_function.
I need to understand how these functions work.

Help.

You will kill your battery at this current. It is only rated for 45 A.

of course I'll use it at 45 amps.
I just made a sample today. But why does he see it as an EM 50

You can try to use the em200 controller program. It can be downloaded from link early in this thread.
It is possible to select correct controller in this.

What could be the reason for the controller not taking the outside temperature into account? (on the engine)
No problem with the cable because the old controller was reading it.

It might be that the 96V controller is older than the EM50.

My old EM150 doesn’t show temp either.

Where did you buy it? I think 96V controller is not a big seller. Current and power rating is low compared to 72V versions

I bought it here from a guy in the forum.
However, I have a lot of problems with this controller,
No program sees it as EM100 but as EM 50
and the settings are kind of confused.
I change some parameter and nothing happens. In a sense, I make a change, then I save it and after I close the program and reopen it, the value is always empty.

I'm talking about this page

Recovering from my old controller gives me an anomaly and shows me a voltage of 56 volts. It removes the settings from the restored file, then saves them to the controller and the controller works with the settings from the old controller, however, by restarting the program and re-entering the controller all values ​​from the last page remain empty and the motor runs with them. This is unrealistic, and the controller works with the specified settings and their parameters are empty.
I don't know what to do anymore I think this purchase was completely unnecessary or the controller has a problem.
I'm already 60% back on my old controller
You're helping because I can't handle this controller.

Also, these parameters, after I set them after restarting the program, remain with the value "0".
I'm going out to do the latest tests and I'll have to decide whether to get my old controller back or so with a half programmed controller.
Help me decide.

Now after the test.https://connect.garmin.com/modern/activ ... nique_id=9
Mileage 39 of my 100% charged battery left me with about 25%. With a claim of 75% the distance traveled is 40km.
The controller settings were made just like my old controller. The maximum amps were 45A and the mod speed was 55A. I used it 3-4 times in 30 seconds,
Conclusion: I will go 50 km a day and thus I will save the battery, because with 55A front speeds and mod 75A speed the battery runs out in 25 km.
I'm already 98% back on the old controller.
Tell me what to do because I'm split.

Something else happened to me today. As I was driving, after about 30 km of transition, the engine suddenly switched off. I drove no more than 40km on a straight road without loading.
Stopping and the engine did not work. When I lifted the seat, the fuse was off. I tried turning it on but it didn't work. It was at least 60-70 degrees warm and I assumed it was overheated. I waited for it to cool down but it didn't work again.
After I dropped the fuse, I do not know for what reason the two DC-DC converters 72 to 12 volts were damaged.
Both burned at the same time. Now I have to buy new ones. I'm trying to figure out the reason why if I buy new and they burn?
Ideas?

PS. Could the engine have been returned to high voltage after the automatic fuse has been switched off and the inverters burned out?
Because now, as I said after the accident, I wrote 99 volts on my board.
Help me to solve the mystery.

Ask about the automatic fuse. Should it be obligatory for direct current or may it be for alternating current.
My fuse was for 12-96 volts DC and 16A - 6000A, but I can't find one. Can I put another one. Today I bought a 16A for 220 volts, but turned it off twice for 2 kilometers.

Can you look at the diagram below and is there an option to remove the 72 to 12 volt converters and use the first battery to get 12 volts from there for the whole motor.
For signal lights, tail lamps and headlamps.
And if not why what would be the problem.

-The first battery will get out of balance, and lower your range as it’s the weakest battery that decides the range.

-I would use a 100 A ”midi” fuse instead of an automatic fuse

-Just get a new dc-dc, doesn’t cost a lot.

Regarding the controller choice: i’d stick with the em50. My first controller was like your 96V controller with the halfway functional program and eventually it just stopped working.

And what is the reason for them to burn?
After switching off the switch, a high voltage was turned on and burned or?

Is that what you mean?

Yes, but so the controller will be constantly energized. Isn't that bad?
And to get my old controller back, the em100 goes to the bin.

Impossible to say why dc-dc burned without doing a complete check of system and harness, all connections etc.

If there are two dc-dc and both dc-dc burned then i’d assume there is a short in a wire that is common to these two. Has to be found if this is the case.

The automatic fuse isn’t your only way of turning off controller? Don’t you have a keyswitch?

It’s not a problem to have controller connected to power always, but it shouldn’t be turned on constantly (not good if someone touches the throttle, due to idle power consumption etc.)

I checked the whole system afterwards and there is no short circuit. With the help of another 12 volt battery, after a thorough check, I ran the 12 volt system and everything worked perfectly. Except for the light bulb for the registration number. She was burned out.
At first I thought it was short on the 12 volt line, but there is nothing like it. Everything works fine. I opened both the disconnectors and the two high-voltage fuses were broken. After measuring the transistor it is burned by giving it a short.
This is a burned path of 72 volts because the pannistor is shorted to a table. I guess because of the high back voltage after my fuse fell while driving, the motor generated high voltage and the controller without current couldn't adjust it. My fuse was 100 degrees and he turned it off. As I said before, the EM100 has some problems, but it didn't work out exactly what, but it didn't work properly.

Yes I have a contact key but it only breaks 72 volts to the killer cable controller.
So, is there no partial consumption left by the controller that drains the battery. I thought that when I was in the parking lot I had to break the voltage not only from the ignition switch but also from the fuse.

By the way, I already got my old controller back.

I'm thinking of putting a 8-10 amp fuse on one of the voltages. but I do not know what voltage will be more appropriate.
Tell me if it makes sense for a fuse and what voltage would be more appropriate to put it on?
