over heating a few mile in?
Im still going back and forth with them on this.
They want me to buy more motors at discount.
Why do I want more motors if 6 of them over heat when on a bench?..
Maytech needs to step up the QC and be a little more helpful when things are bad on their end.
I can give some snippets of the email if needed. Sad to see this happen to more than me, but maybe this will help to prove to them, there is/was an issue with some batches.
I was told no one at all reported issues, etc etc. again I can provide snippets if needed but I digress.
If outside temperatures are over 30C and you ride aggressiv itâs very likely that your motors overheat. I get my open APS 6384 over 80C in 10-15min if itâs hot outside.
Wouldnât say itâs a maytech problem. More a problem of the motor design and the way we use them.
Went for a ride today at 28C after talking to Maytech. When I addressed the issue with Maytech, they said because of the design of the sealed motors it is typical for them to run hotter and the max temperature of 90-100 should be no problem. After a quick ride to the store I realized the Metr wasnt recording so this log is after the motors had gotten up to running temperature already. Unfortunately during the ride I noticed towards the end that the acceleration had been pretty much squashed. I was full throttle and only gradually accelerating compared to before. There were times when I experienced a stutter effect as well where the motors were only receiving limited power thought it looks like temps were staying under 75c for the most part. What might have caused the loss in acceleration and power cuts?
Interesting you say that because the metr does say max temp hit 85c but the graph only says 75c. When the stuttering happened I didnt see the temps up past 75c. My motor cutoffs where set at 80c/ 95c. I will up them to 90c/105c and see if it helps at all.
Edit- I changed the metr graph view and can see where I hit cutoffs on motor temps
Keep in mind the acceleration temperature decrease will lower the maximum temperature during acceleration to leave room for braking, this is why itâs cutting before reaching the values youâve set
I havenât personally tested, but I have a friend that is running one from a 3S pack, let me check with him if he did test it with the battery fully charged
Im calling BS on that.
I have 6 motors (well had 6 over heating 10mm shaft motors.)
I have four 8mm Maytech in the same 190kv etc etc.
The 8mm have no issues and can run them at 12s lipo
all day, up hill, etc etc. They are great!
This is why I bought 6 more but decided to go 10mm shaft since
the 8mm one is shorter and I need length for the builds I have.
Now if sealed is the issue, why does 8mm sealed motors work fine but the 10mm ones donât get but a few miles then feel like the sun? Im calling BS, since my real world testing shows otherwise.
Seems Maytech is trying to make it your fault somehow imo.
