Spring come,nice days to ride e-bikes.But when you take out of your old e-bike from warehouse and are going to ride it.Suddenly you would find there is strange noise from hub motor<\/strong><\/a> .
\nThese days the electric bike motor<\/strong><\/a> are brushless gearless and used for electric bike widely.It was made of rotor-winding,magnet,hub,covers,axis,bearings…
\nIf this bike motor<\/strong><\/a> has strange noise,generally it’s from rotor-winding rub magnet or the bearing is broken.It’s easy to solve it.The important is to disconnect this electric hub motor.
\nYou should prepare some tools:
\n1.Hexagon wrench (Necessary)
\n2.Hammer (Necessary)
\n3.Screwdriver<\/p>\n

Disconnect hub motor Step 1:
\nTake off nuts and gasket on axis and use hexagon wrench to loose 16 screws.<\/p>\n

Step 2:
\nMake the hub motor stand and cable is bent inside.Left hand hold the hub motor and use hammer to knock the axis.<\/p>\n

Step 3:
\nAfter some knock,the cover will take off hub.<\/p>\n

Step 4:
\nUse the same way to knock the other axis,the other cover will also take off hub.<\/p>\n

Step 5:
\nWhen both side covers are off hub,next we should take out the rotor-winding.Make the axis stands on the ground,both hands press hub motor,the rotor-winding will out of hub.<\/p>\n

Step 6:
\nCheck magnet around inside hub,if there is some metallic impurities stick on magnet.Please remove it.If no,but found some friction trace on magnet.Please check around the rotor-winding and remove some glue around the steel.If not,please check the bearing inside the cover.Use a little finger hold inside the bearing,use the other hand to turn cover,faster,better.If you hear some noise.Please replace bearings.<\/p>\n

By now,you have solved problem. <\/p>\n","protected":false},"excerpt":{"rendered":"
