We specialize in Allen-Bradley MPL, MPM, and VPL series servo motors, restoring them to OEM specifications or better. Our repairs are cost-effective, reliable, and backed by more than 25 years of servo system expertise.

Our Capabilities – Beyond Basic Motor Repair

We go deeper than just rewinding or replacing bearings. At Star Automations, our servo motor services include:

• Resolver & absolute/incremental encoder alignment
• High-speed rotor dynamic balancing
• Shaft runout correction & polishing
• Rewinding with thermal Class H copper wire
• Insulation resistance & surge comparison testing
• Load simulation & thermal stability analysis
• Pre-delivery report with waveforms and test video

Common Critical Faults in Allen-Bradley Servo Motors

• Encoder feedback dropout (causes axis misalignment)
• Overheating coils due to insulation breakdown
• Bearing seizure from lubricant degradation
• Inverter surge damaging stator winding
• Loss of commutation sync in high-speed cycles
• Environmental damage (dust, oil mist, coolant ingress)

We use modern ESD-safe equipment, multi-axis test rigs, and OEM-grade spare parts to return your motor to peak performance.
