Ancheer controller replacement

[ra'amyah 613]

Hey peoples,
Noob here. Have an Ancheer ama5929, 2023 26" Step through "Swan" bike and I'm the second owner. Got an E10 error code (EN06 display) and went to trace it. Finally ended up in the controller with what appears to be an inductor that is getting VERY HOT 5-10 seconds after being energized. Ancheer says 2 months to get a new controller. Paugh! Need it quicker than that! Looking at controllers on Amazon was fruitless - this looks to be a proprietary deal - makes NO sense but oh well. Will include pics. The two big cables (motor and display?) are wired directly to the board - damnifiknow what the individual wires do, no wiring diagram.
Does anyone know an aftermarket controller available to replace this??
500w, 10.4A battery, rear hub motor, 120° hall sensors, smooth sine wave, light and horn worked when it wouldn't move. Love the bike, done 500 miles in six months, did great until I tried the controller? Ancheer has very little support available - brakes, no; controller, no; spokes, no; displays, no (until I begged - swear they created a web page just to finally sell me one - it wasn't there before!). Anyway, I've looked on forums, YouTube not finding this anywhere and not bright enough to learn all there is to know on controllers.
Help?

Is there a quick disconnect motor connector or does the Ancheer run the cable direct to the display? That will guide your choices,

Trust me you don't want more of what came on the bike originally. Ancheer makes about the crappiest e-bike I see often enough to have a nuanced opinion about the brand. Every element of every Ancheer bike I've serviced has been garbage. I'm not averse to using garbage grade components that work well, but that's not my impression of Ancheer so far.

A propos the question asked by @docw009 , every Ancheer I've had to service doesn't give a practical way to detach the hub motor wheel to do flat repair or anything else. There's a long motor cable that disappears into the battery box where the controller is enclosed. Inside that, there are bullet and multi-pin connectors for the motor, but that's a lot of shop labor to throw at something they should have equipped with an accessible plug. But it shouldn't take any amount of rocket science to attach the motor to another cheap controller.

His controller does have a 9 wire motor cable, instead of discrete phase/sensor wires, so it might use a molded connector.

Some newer ancheers even use controllers with the waterproof connectors in the battery cradles for what look like Hailong batteries. Still not plug and play though,

Unless you want to buy a new controller/display combo and wire all components to the new controller, you’ll have to wait.

I say the controller and display, because you can’t just toss another controller, that looks right, in there. The display is “married” to that controller. Unless the controller comes from the manufacturer, which you have already initiated. You’d have to get a new controller that comes with a display to be sure they will work together. Then you’ll have to suss out the wiring and get that hooked up.

It does indeed have a molded 9-pin connector - one for the motor and one for the display. They are of different lengths. One goes into the chassis bundle before attaching to the display at\outside the handlebars, the other one goes through the chassis straight down the bottom of the seat post for the motor. I have only seen fairly short extension cords on Amazon. The initial connections, on the PCB, for both 'cables', are direct wires, individually soldered with no way to trace to the connector.

Through all the silliness (thinking it could be the display that was the problem) I have ended up with 3 working EN06 displays. To the best of my understanding they are UART2, self adjusting to voltage, self adjusting hall sensor, for smooth sine wave, cruise capable, etc. It appears the brakes (low?) are not included in the display bundle even though the display did show when the brakes were engaged. Each brake has an individual cable for the sensor/trigger leading into the bundle/harnass, but I am unsure of where they attach at the controller.

Is there a controller that might fit for this configuration with or without using my existing EN06 displays?

 

[ra'amyah 613]

Sorry, messed up, cuz I'm doing it from memory, sigh. The display cable is a molded 5-pin connector and the motor is a molded 9-pin connector.

 

[ra'amyah 613]

If I was not being clear (cuz I'm a little slow) they both are connected by molded connectors coming out of respective exits from the chassis.

The Z91 looks correct for the display? 5-pin?

Yeah. I was able to open the hub to see if the motor needed cleaning or demonstrated lack of continuity but no way to remove the whole motor - attached to spokes. Planetary gear was also intact and okay. I agree that motor cable is not easily accessible from the controller as it originates from individual wires on the PCB to bundled cable straight to the chassis where it exits to a molded connector hooked up 8 or so inches from the motor's own cable.

They are indeed waterproof connectors though I have seen more competent connectors (neighbor's Walker H7) where it screws up to the mating connector.

Wallke H7 I meant

Quick disconnect for both motor and display .

The other EN06 may not work because they used different firmware intended for some other controller.

It appears you have a Z91 motor connector for the motor. I see the smaller handlebar harness going forward to the handlebars. There is a molded connector in your picture just before the seat that looks like part of it? The harness is more than 5 wires, as can be seen in the controller shots... red, blue, green, yellow, white, brown. Is there a black in there too? Should be a 5 pin molded plug at the handlebars for the EN06. SHould see connectors for the brakes too. No throttle? The red/blue/black connector on the controller circuit board must go to the pedal sensor.

If you want the easiest repair, best bet is to wait for a new Ancheer box, The handlebar harness is probably proprietary to the Ancheer.

If it were my bike, I would buy a 17A KT sine wave controller with waterproof motor connector, a KT 4n1 harness, KT display, throttle and pedal sensor. Something like this, They offer 9 pin extensions to reach your motor, if needed.

One thing I don't know is whether it's a 350 or 500 watt motor or 350 / peak 500. Not a clue. Pictures attached with a little bit better detail. Thank you for the suggestion. It looks like it could work. Could you please review the photos and see if the suggested product is still apropos? And I still have no idea how/where the brake sensor wires are!

Throttle is full twist on the right handlebar, no idea how all that is wired! Battery is 10.4ah.

Ancheer says: "It is a 48V15A controller, we do not recommend you to use controllers of other brands, because they may not be compatible and may also cause other problems." I'm not so believing them right now because of low support for their product.

Interesting thread, and probably appropriate for many individuals with similar challenges. I would explore purchasing a complete kit which (on sale) could be < $200. Then the "only" problem would be connecting the kit to the battery. I was able to do that on one occasion.

 

[docw009]

Others may disagree, but I consider the Z91 pin motor controller a standard, If it's on a motor, any controller will run it. The watts is a consideration, but that's up to the rider to take care of the motor.

If you can spin the motor, then you have the choice of a plug-n-play where everything is replaced or the solder-n-pray where you try to make the old parts work with the new controller. I gave you a solution where it's all on the same website. You could probably save 20% buying parts ala carte and fashioning your own connectors.

I believe though that the Ancheer handlebar harness is proprietary like the display, When you buy a controller, you need the matching display and harness. Unless you can solder and figure out wires, might as well buy a matching throttle and pedal sensor. Your horn and lights won't work either. Those need to be replaced.

Told ya I was kinda slow... Heh heh. When you say spin the motor...?
