Upgrade Questions

HUMMM…

Was the belt on too tight?


#3

no it felt pretty loose. motor still works surprisingly, but I don’t trust it a bit.


#4

Sadly, it needs to be rewound. There are a lot of guides online, plus side is you can alter the kv/improve efficiency if done well.


#5

Wow … Need more info bro…there is some reason it heating up… I’d re-check phase wires…make sure the tips of the bullet connectors aren’t touching … Hand spin the motor… Is it smooth? Or is something grinding or giving it resistance…


#6

Need more info about your setup with pics


#7

I can’t even take off the housing because the Allen key holes are stripped. I received the motor like that :confused:


#8

The motor is smooth, only resistance I get it the belt tensions. It could be the wires because I took off the originals and replaced them for less stiff wires. Though everything it wrapped in heatshrink/electric tape.


#9

Not at home so can’t take pics, but all of my electronics are here


#10

Were you going up a hill? I find that without a VESC, my board doesn’t limit the amount of amps going into the motor, which is a problem up hills because there’s more load and obviously too much power can blow your motor. If you have a VESC, try limiting the amount of max power to the motor.


#11

I went on a 4 mile ride, some hills:

The motor would stutter going up hills so I walked them.


#12

Oh and I don’t have a vesc though I am considering buying one now. Suggestions on where to buy from?


#13

The stuttering is some type of short…if the phase wires intermittently touch you can get the jerking motor…also signs of a burned out motor


#14

This whole statement is confusing…How the heck did the motor come with stripped bolts???


#15

There is another thread going on now that addresses the reason motors and Esc’s burn up.
I plan on doing some testing myself on the 3 phase side of the Esc and will post my findings later today.


#17

I don’t know how, they just did.


#18

drill the heads off the screws and pull the can off then remove the screws with plyers


#19

I’ll probably do that. Or maybe make a slot with a dremel for a flathead screwdriver.


#20

Smart! Aren’t most of these motors just held together with a circlip like this one from enertion?


#21

I have that motor. If u can get it off the mount its rotor is held connected with just a c clip like all of them. The pic above. On the shaft closest to the center
