Common servo motor problems
Food manufacture
Machine wash-downs by jet wash, steam hose and caustic solutions cause water and fat ingress, heavy corrosion of the motor casing, and contamination of the feedback device. The motor OEM sealing for this kind of environment has often been under-specified.
Stiff Materials Processing
Dust gathers around the oil seal, eroding the drive-end shaft. The motor shaft is frequently placed under extreme torque. The bearings, bearing housings concentricity, shaft journal integrity, trueness of the shaft and the keyway tightness are often compromised.
Metals Machining
Oil, coolant and/or anti-weld fluid ingress into motor windings. Oil seal wear in drive end of motor shaft. Similar damage to paper industry motors. Fluid-borne contamination of the feedback devices, metal machining servomotors often have additional feedback devices for the main machine's use.
Bottling, Glass Production
The problems we encounter with these industries are often very similar to those found with metals machining plants. They include serious mechanical damage and fluid ingress.
