Re: Sinusoidal wave brushless motor controller

Hi tuxadmi. Could you share what you learned about the serial protocol used by the KLS controllers? I took a crack at reading the serial commands, but it doesn't look like ASCII characters are used. So before I start analyzing with the oscilloscope I thought I just ask you about it. It looks like 19...

Re: MAC vs Bafang

I haven't tried the 500dd, but if I compare mac against MPIII its not buch difference in volume. I put a sine wave controller on my Q100 and that made a big difference, goes to show that a lot of the noise is generated by the motor and not just the gears. I guess if you find a sine wave controller t...

You can select LVC in 0.5v increments between 19v and 66.5v according to the software.

Re: 8Fun CST 250w and 350w, what is the difference?

I didn't buy the 8Fun CST so i can't say how that works with 10speed, but I did buy a qute q100 cst and that needed extra 2mm for both standard 8 speed cassette and my 10 speed Dynasys cassette. The 10 speed cassette isn't much bigger than the 8 speed, the gears are closer and it uses a special narr...

Re: Which throttle for mountain biking?

I have the thun/CA3 setup on two of my bikes and while it works very good 99% of the time I have found that when you need to do some tricky trail maneuvers you want that torque sensor disabled and use throttle instead. The reason is that the Thun doesn't detect torque more than once every revolution...

Re: European regulations

The motor has to cut within two meters of stop pedalling. The 5m applies if you have brake cut-offs. To qualify as brake cut-offs, they would be expected to cut the motor immediately. The power is allowed to run on for 5m without using the brakes.The idea is that when you want to stop, you don't ha...

Thanks, bought it and got it! Is it the side with the cables i must unscrew or is it the other side? You definitely want to open the freewheel side of the motor since you need to route the sensor cable trough the controller cup and out that side unless you want to drill new holes. It should be poss...

Re: New Cute Q100 replacement? The Q140 CST

The spacing between the 11 teeth sprocket and the frame is actually 4mm less than on the original wheel (the 10speed wheel had only 1.6mm more space). The b...

Re: New Cute Q100 replacement? The Q140 CST

My Q100 201rpm Noload measured at 18mph. This put me at 226rpm at an assumed 40 volts, or 200rpm. Either way, the motor would do about 15mph on its own. I don’t remember seeing anyone else who actually measured the motor speed until this thread. I’m kinda surprised the 140CST would spin that fast. ...

I got 269rpm at 40.1v that equals to 6.7rpm/v and 241.6rpm@36v.
201rpm@36v wasn't very true then.

How is the torque and speed of the new motor?
You have to give me a few more days. The motor hasn't arrived yet. According to FedEx it wont arrive until Friday, but it arrived in Oslo yesterday so I expect it here sooner. I'm guessing the torque and speed will be the same as the Q100.
