FANUC Motor (series lists)
FANUC of Japan have produced over 15 million FANUC motors. DNC has a dedicated Fanuc motor engineer purely working with FANUC servo and AC spindle motors with purpose build FANUC systems and FANUC drives systems to test, inspect, diagnose, rebuild, rewind, clean, overhaul, replace motor components, and lastly paint. DNC offer exchange on 1000’s of different motors, repair services on 10’s of thousands of FANUC motors. This list below is our series of supported FANUC MOTOR models.
FANUC Motor models @ DNC
DNC constantly try to improve testing facilities for FANUC motor models. Either in increasing the differing series of motors such as the ai series 02xx and the emerging 22xx series of motors being fitted on CNC machine tools today with 0i-MF / 0i-TF / 35i controls, etc.
When motors are sent into us for inspection we follow this procedure.
We visually inspect your FANUC motor for signs of liquid ingress, mechanical damage to the rotor, stator housing, near and end bearing housing, encoder and the end cap or fan. Assuming a problem is detected visually then we will deal with that before proceeding further. If not and the mechanical appearance is good, then we will MEGA the windings and do other tests (such as the brake releases if fitted). If the winding’s are down then we will advise. Otherwise we will look for electrical issues with the encoder / tacho / sensor, assuming nothing obvious then we will do a basic test with our feedback testing rig. If OK, then we put your motor(s) on one our rigs with the correct FANUC drive to suit the motor.
If the motor exhibits bad winding’s, encoder feedback, stiff or locked bearings, faulty brake, or damaged shaft then we will be in contact with options such as replacement, repair and rebuild, rewind, etc. Once works are carried out on your motor then it will be tested on the appropriate FANUC control and drive system to run it at various speeds, etc.
FANUC motor repair turnaround
Obviously the quickest solution is to take an exchange assuming that its in stock and your motor is acceptable for our service exchange conditions. If no stock or looking for a solution on a non exchangeable motor such as regular motors we receive. Bad winding’s, bad sensor, bad bearings, damaged shaft then we will hopefully find a solution. Our turnaround is normally 24 hours on all motor repair work if winding’s are not an issue. If the motor has shorted winding’s then we will advise on quickest course of action. Either we have spare winding’s for your motor series or it will need to be rewound which is a 5-7 day turnaround.
