Noise DD

[Kirill]

Hello everyone.

I installed a new unused DD motor Suringmax SR35HD 1500 (Clone 9C).
After the geared Bafang BPM and MAC, this DD seems very noisy. Even faulty.
Tell me, is this noise a breakdown or a malfunction?

I tried to do something in the Kelly controller settings.

Turned on the noise reduction function. (Nothing changed)

Changed the angle of the hall sensors 60 or 120 degrees. (Nothing changed)

Ran auto-identification several times. (Nothing changed)

Ignore the whistling sound from the brake disc.

It doesn't matter which way it rotates, there is noise and crackling.
DD Suringmax 1500 W motor. Set it up remotely by a Chinese engineer after contacting the seller on Aliexpress. But their setup was not completed. It just turned off.

I watched the manufacturer's manual and various YouTube videos on setup. After watching, even more questions appeared.

1) There is no strict procedure for self-identification. The colors of the wires for the short are different.
Self-identification was not successful.

2) Has the opinion that flux-weakening can lead to burn out. What parameters should be set of flux-weakening for uninterrupted operation?

3) During setup, there was an error with the motor halls and the controller failure. I don't know what this is connected with.

As the wheel decelerates, the rhythmic sound to my ears points to a warped brake rotor.

Based on my experience, that buzzing/ratcheting noise at the beginning is perfectly normal and a consequence of the square wave signal from the controller.A sinewave controller can get rid of it. I'm guessing it is louder with this DD motor because the larger side covers that make for better resonators.

Ignore the whistling sound from the rotor please.

Apart from the noise is the performance good?

 

[Kirill]

All good now?

Little bit. I only install motor with my old noname cheap controller and just try to set and to connect Votol controller.

Really keen to hear about the performance of this motor.

They (Suringmax) do high powered controllers and torque sensing as well. And the price is low for the motor wheel and shipping

Their website mentions Power Steering in E-Bikes & goes on to say "Torque Sensors: Measure the force applied by the rider to the handlebars"

Since they're talking about using actuators to actually steer the bike for you (or rather, help steer it), then that makes sense.

But I can't imagine a regular bike that would need such a thing.

A big front-loading cargo trike, where the cargo is steered by the rider along with the front wheels (rather than sitting on a subframe attached to the main frame and not steered along with the wheels), sure, or maybe a cargo bike with huge panniers / baskets / etc mounted to the front fork/bars so they have to be moved with the bars.

Power steering on a bicycle? From their website I am judging this as pure horse pucky.

Hi everyone!

Can I replace the SS41F motor hall sensor with SS413F/SS443F?


Data sheets is attached.

Hi. Can I replace the SS41F motor hall sensor with SS413F/SS443F?

 

[fechter]

Those seem like they should work.

Hi, everyone!

The DD Suringmax motor with the Votol EM50-4 controller doesn't work.
I would even say it works, but according to the Chinese Votol engineer, it is impossible to work.
He tried to configure it remotely twice, but nothing worked. Although it started the motor remotely and even worked smoothly and well. But sometimes it was noisy.
In the end, nothing good. The motor doesn't work. The self-identification process didn’t complete. The wheel made one turn, but then nothing.
I also contacted my Votol specialist. He also couldn't.
Before buying, I clarified whether the Votol controller would work with my motor, in Suringmax answered 'yes', but and now they say 'no', works only with their QS motors. And they say that the problem is in my motor and hall sensors.
The manufacturer Suringmax claims that the motor has SS41F.

Votol rep states that their QS motors typically use SS443F/SS413F.

Is it acceptable to replace SS41F with other hall sensors?

Thanks!

I have the same question right now ?
They say in and out it sounds like bipolar as what I need.
SS41A is what I used to use.

@Kirill can you report back on the motor’s performance?

There are also high powered controllers on the website, interested to hear if anyone has used them

 

[Kirill]

@Kirill can you report back on the motor’s performance?

I'm at a dead end.
It’s the end.
I did everything.
I don’t know what do next!!!
While I'm looking of a solution to the problem, I decided to check the motor's Hall sensors. Despite the fact that everything works fine with the Noname controller. I took measurements. The voltage of one Hall sensor is 2.38 V and doesn't change when the wheel is turned. The other two hall sensors values change. So it is faulty, I decided.
I replaced all three as properly. Nothing changed. The same sensor with a yellow wire has a voltage of 2.37 - 2.38 V.
And nothing works with the Votol controller. Self-identification doesn't complete.
But with the Noname controller everything works fine.

 

[Kirill]

As you could read above I created another topic and I already got problems with the new Votol sine controller.
Only Noname controller works fine.
I tried to perform self-identification in the setup program by changing the PD1 parameters to 22-_e_gear.
But again a message appears about no connection with the controller.

 

[Chalo]

If you have a known quiet controller to try with the motor, do that. In my experience, most DD motor noises are actually controller noises.

 

[Kirill]

Of course I could leave the noname controller but I want to get more speed with the flux-weakening function.

 

[Kirill]

I solved the noise with the Kelly square controller by purchasing a Votol sine controller.
And I got a new problem - the impossibility of proper work at all.

 

[yantra yatra]

Apart from the noise, is the motor good? Or can’t get it to work even noisily?

The motor works fine. But with another noname controller.
Problem with Votol controller.
