eBay "RisunMotor" 45A sine wave FOC controller

Post by E-HP » Nov 05 2019 1:20am

I'll be reviewing my latest eBay ebike purchase, a "RisunMotor" sine wave FOC 45A controller. I received the "mystery" RisunMotor controller today. I call it a mystery since my current controller was also bought on eBay, and also a "RisunMotor", but actually a KT sine wave controller and LCD3. Anyway, this controller didn't appear to be a KT design, but has the voltage flexibility (36V-72V) I was looking for, plus all the other features I'm used to (PAS, regen, etc.). Very few controller fit the bill, and none looked like this one, hence the mystery. The label does say "RisunMotor" on this one though. :?:

The first clue as to what the mystery controller might be came when I received the links to the documentation for the controller, display, and bluetooth app. The display manual was a generic 750C manual; the controller "manual" was just photos and the description of the connectors. But the bluetooth app manual has a picture of a Sabvoton (or clone) controller, and the app is downloaded from MQCON's website.

Anyway, this is what showed up:

eBay listing with description and features. I guess I get to see how FOC works. Also, I noticed the app has some flux weakening settings, so some new stuff to play with. I'll cross my fingers that the controller doesn't experience the reliability issues I've read about for the current Sabvoton controllers.

RisunMotor programmable sine-wave motor controller works with high efficiency, less noise, and lower energy consumption, which makes your electric vehicles or electric motorcycles more comfortable and easier to control. Our designed friendly interface of the programmable motor controller makes you set the parameters, conduct the tests and obtain the diagnostic info easily and quickly.
1. FOC-180° sinusoidal drive controller applied to BLDCM or PMSM.
2. It takes only 2-3 minutes for the motor to be well matched on its best electronic angle at the first time.
3. The motor torque ripple will be reduced to the minimum, so as to ensure electric vehicle to run without any noise and vibration, smoothly, and comfortably.
4. The precise current ring can provide accurate torque input to meet the requirement of large torque output during vehicle starting and climbing.
5. The controller enjoys high efficiency due to space vector converter control algorithm which can effectively reduce the temperature rise of controller and extend battery life mileage
6. Built-in various protection: locked-rotor protection, over-current protection, overload protection, over-temperature protection, speed protection, over-voltage protection, under-voltage protection and so on, effectively ensuring the safety of electronic control system and vehicle.
7. System status and fault intelligent management system can effectively monitor the current system operating mode external input state, the case of system failure, and the LED flashes at the same time to facilitate the diagnosis and maintenance.
8. Multi peripheral interfaces: reverse, cruise, anti-theft electronic brake, etc.
9. Parameter modifications and settings are available through Mobile phone via Bluetooth or computer via USB data cable
10. CAN BUS is optional to communicate with body instrument and BMS


I couldn't really picture what the size of the controller would be, even though I cut out some cardboard to the dimensions listed to see how it might fit on the bike. But it turns out to be smaller than I thought, although pretty chunky at the same time. About the size of a brick, but only about 3/4 of the length.

Actual length is 1/4" less than a $20 bill, and the height is 1/4" less than the width of a bill. Chunky, but I have a good idea about how I'll mount it.

I won't get around to installing this thing until the weekend, but maybe i'll power it up to check out the bluetooth app or something.

Of course it hasn't gone smoothly. The very first hiccup has been with the bluetooth module. After a lot of messing around, my conclusion is that the module communicates like it should with either my iPhone of android tablet, but the module is not communicating with the controller.

Symptoms are after connecting, the parameters screen, which should read the controller settings, reads all zeros. The settings screens appear to allow updating of the settings, and says they are saved, but none of the setting save to the controller. The modules acts the same as if I just plug it into my laptop (to power it) and connect to it with my phone.

I've emailed the seller. Miraculously though, with the throttle attached, and just plugging in the phase and halls, the motor runs smoothly. It appears to actually be running faster than with my other controller, so perhaps the field/flux weakening setting is set to ON? I haven't tried setting up the PAS yet.

If anyone else has had problems like this with the Sabvoton bluetooth module, I'd love to hear how you go around them.
