EV Motors are easy to rebuild with the correct tools.
This motor was removed from a street legal home built Electric Vehicle Conversion.
When opened up we found the unit had a lot of corrosion & the motor brushes were completely seized.
We turned the armature on the lathe, and cleaned & polished all of the parts.
We replaced the bearings & packed them with NLG1 grease.
Upon testing the unit was quiet as can be and was running very efficiently.
When not fixable we also sell NetGain, D&D, GE, Advanced DC, and Baldor motors.
