Re: not a happy mac motor - help needed

Dan, thanks for your words of wisdom, I'll try that colour combo this weekend and see what happens.

On a separate note that is quite some alchemy to be hitting 40mph on a 6fet controller on 15S of LiPo, I'm guessing you are pedalling like a nutter at the same time?

Re: not a happy mac motor - help needed

Well if you are using an entirely different motor but the same controller as me, and getting the same symptoms, logic suggests it's the controller having difficulty with these geared motors..

With the motor rotating at 1500RPM the controller looks like it's losing sync under load

Re: not a happy mac motor - help needed

Haha! What a great tip. Now the motor is working great. Except... for the jittery problem you're describing. I'm finding that I have to baby the throttle during acceleration or else the motor will cut out entirely or judder during initial acceleration. Almost as if the power is cutting out during a...

Re: not a happy mac motor - help needed

ok, cellman controller is late 2011, when used with my mac 10T it's an absolute dream, no juddering, really really smooth throttle response 8T mac with Lyen controller, no end of trouble 8T puma with Lyen controller, fine, but it doesn't do slow, a little rotating and BAM it launches off with a kick...

Re: not a happy mac motor - help needed

what you've got there, is a motor working in reverse, think about the way the clutch works, the motor is just spinning backwards which it can do freely, nothing wrong with your clutch. Keep trying phase combos, for me it was blue and yellow reversed but now im left with the juddering under load. I'l...

Re: not a happy mac motor - help needed

Another interesting observation for all mac fans out there... noise The 8T mac was notably quieter than the 10T mac on my commuter, and then it dawned on me, it's not the motor that's noisy, it's the frame... On my commuter the downtube is a really thick tubular round aluminium pipe, and it's where ...

Re: not a happy mac motor - help needed

Spacey seems like your problem is different, when I had the phase wires wrong it wanted to spin WAY faster but was pulling way too many amps and had no power. now I have the phase wires "correct" the motor is smooth and spinning in the right direction but still having the juddering problem, perhaps ...

Re: not a happy mac motor - help needed

As I say earlier in the thread, I've swapped the phase and hall combo which now results in a smooth running motor, I havn't checked the no load amps but it might still be too high. Under no load it behaves perfectly but under load it does that constant cutting out thing 2 or 3 times a second. The sa...

Re: not a happy mac motor - help needed

The juddering only happens at high load, regardless of speed, worse at takeoff due to naturally higher loading. No speed switch, doesn't even have a plug for one. Throttle is an eBikes.ca one I changed the plug on to fit the lyen. The speed limit on the CA is 99mph. This is a strange bug indeed, onc...

Re: not a happy mac motor - help needed

swapped blue and yellow phase and hall and wahey, we are off!!!! that's more like it, smooth and quiet, a LOT quieter than my other mac motor, or more likely, frame. The schwinn has a really fat tubular frame, most of the sound seems to come out of the front so I think the resonance is transmitted t...

Re: not a happy mac motor - help needed

I can confirm that when the clutch fails, it results in the motor not being able to freewheel, that isn't the case here. It looks more like an electrical issue, but that doesnt explain how the motor *appears* to be spinning free inside the casing, unless!!!!!! it was spinning backwards due to a phas...

Re: not a happy mac motor - help needed

Neptronix, thanks for replying, I was really hoping you would weigh in on this one, my other 8T i copied the wiring from is indeed an old Puma motor which even has a different sized axle entirely so It's not far fetched to imagine the phases might be in a different order, next time I will have to wo...

wired up this mac motor just like my other working mac motor and this happened.... vFFoBOqNNQo The motor is brand new and is wired up to a Lyen 12fet with the same wires / colour combos as my other mac 8T which is of the earlier, none disc design. I tried going out for a ride and it just wasn't havi...

I can't remember who on the forum said it, but "one test is worth one thousand simulations" whilst the eBike simulator is a great tool, nothing beats getting out there and running a motor to within an inch of it's life and finding out, in the real world what it's limits are, and you don't have to br...

Re: I just went from a 6 turn to an 8 turn Mac

Personally I wouldn't take a mac trail riding, I'd want a direct drive for proper off road, I've heard of macs getting trashed because if the wheel is air born and the throttle is applied, the wheel touching down and meeting sudden massive resistance will trash the plastic teeth on the gears. It wil...

Re: I just went from a 6 turn to an 8 turn Mac

my everyday commuter is a 10T mac running on 44V with a 35A limit on the CA in a 26" wheel with 2.5" tires. It cruises along top speed of 24mph and it will quickly reach it's unloaded speed even on a fairly steep incline. It powers up steep hills no problem. Launches off the line like a champ I also...
