    Noisy halls on sinus controller

    The PWM is 10kHz (measured on the output) and I can see some voltage drops right when my clicks appear, but there is no change in the pulse width. I'm thinking the the 50kHz might be from the power supply I'm using to test the motor (a battery charger not meant for this usage). Anyway, I...

    Noisy halls on sinus controller

    Hi. I have a Golden Motor HPM05KL (5kW BLDC) and a Kelly KLS7250D Controller that I have connected together. I seemed to work nicely except some slight clicking noise at high speed that I didn't think too much about. But when I applied load to the motor it started to make very hard knocks which...

    Sinusoidal wave brushless motor controller

    The PC software does not work on my Win10 version. I get Software version does not match, please use the latest software. I have now played a little with the RS232. It seems to be using very simple 8 bit binary strings. To make it easy the phone software lists the everything in the same order...

    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...

    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...

    Golden Motors - New Smart-Pie Motor?

    I have and I have read a few more (2 or 3) that also have had problems with the internal controller on the SmartPie. I swapped mine for a external one from Lyen. http://goldenmotor.com/SMF/index.php?topic=4747. First fault I had was a loose connector inside the controller, easy fix. Next time I...

    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...

    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...

    help making the ebike pedal assist?

    From what I read in the first post it sounds like you are looking for a way to drive the wheel with the motor without rotating the pedals and/or pedal without dragging the motor. All the answerers above are concerning PAS as your topic title indicates, but if this is not what you are asking for...

    GoldenMotor MP3 in Trek 2013 29er, great combo!

    Hi, I just noticed this thread now and those winter riding videos are very cool and makes me miss winter. I have ridden my SmartPie a lot in the snow with studded tires and it is amazing fun. The smartPie shares the same problem with the internal controller as the MagicPie3 and I broke mine...

    Alternatives to the BMSBattery hubs

    I have bought kits from bmsbattery greenbikekit and elifebike and I can't say there is much difference. Elifebike lace the wheel in a srange way, i think it was called over under or something, but it was by far the straitest of the wheels. Greenbikekit has been the fastest and bmsbattery the...

    European regulations

    When riding at top speed (27km/h) 2 meters go by very fast while the pedals don't move too fast (depending on gear ratio). I'm wondering how the standard 5 magnet PAS ring copes with that? I don't have brake cut off at the moment because of hydraulic brakes, but I have ordered a 12 magnet pas ring.

    Which version of cycle analyst for Magic pie 3?

    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 possible to get a small cable trough the same hole as the phase wires, although I haven't tried this...

    European regulations

    I think I have decipherer the formula now: P=m*(2D^2/T^3) P = power (watts) m = mass of bike and rider combined (kg) D = speed when hitting the 20 meter mark (km/h) T = Time between starting off and hitting the 20 meter mark (seconds) I tried the formula with my bike Q100@14amps (manufacture...

    European regulations

    The safest is probably to buy a kit from a distributor that clearly states that the kit follows the EN15194 standard (or that the motor is 250w according to EN6034-1). The good news is that a manufacturer can choose to run a 250w motor at way above 250w if he is willing to subject the motor to...

    European regulations

    You can find lots of information in the EN15194:2009 standard. For the 6km/h limit the standard says the following The standard also defines a EPAC as There is also a definition of the continuous rated power: What this means is that the motor is allowed to give more than 250w as long as it...

    New Cute Q100 replacement? The Q140 CST

    I tested my 8 speed cassette on the cute 140 today to see if it fitted any better than the 10 speed did. Surprisingly it actually fitted worse. 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)...

    New Cute Q100 replacement? The Q140 CST

    I'm sorry I didn't know the right terminology, English isn't my primary language. As mentioned earlier in the thread the Q140 is 5mm wider than the standard dropout thats 135mm, but this wasn't a problem when test fitting it. The picture comparison was against a front wheel version that is only...

    New Cute Q100 replacement? The Q140 CST

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

    New Cute Q100 replacement? The Q140 CST

    It doesn't look like they've done that here: After having a second look at the motor with the chain rings on it I can see that I'll need a washer at about 1.5mm thickness for it to work without having to adjust the dérailleur. For the build I'm doing now I think I'll just use the front Q100 to...

    New Cute Q100 replacement? The Q140 CST

    I have now uploaded a video of me testing it to see if the motor works. The sound quality is surprisingly poor on the camera, but you can hear that the ticking from the cassette is very loud and the motor is barely audible above it. My Q100 freewheels much better than this one, but it might...

    New Cute Q100 replacement? The Q140 CST

    I just bought myself a tuning stand (Park tool TS 2.2) so next time I'll try to do it myself.

    I stand corrected. They did a good job then. That made me much happier.

    New Cute Q100 replacement? The Q140 CST

    I just got the M140 from elifebike.com and I can safly say that this is the first and last time I'll buy anything from them. First off I got a mail saying it will cost $75 extra to ship the motor and rim if they lace them together for my. I'm thinking thats OK as it means I don't have to lace it...
