Overview
The Omron R88M-W1K315F-S2 is a powerful AC servo motor of the 1.3 kW class and part of the R88M-W series. This series was designed for high continuous load, precise speed control and use in demanding CNC and industrial systems. Due to the robust torque behavior and compatibility with Omron W servo packs, the motor is ideal for machine tools, powerful axes and automation with high reliability.

- Keep the environment clean (avoid dust, oil, coolant)
Repair description
- Incoming inspection: visual inspection, insulation measurement, winding resistance, encoder line test
- Disassembly & cleaning: open motor, clean stator/rotor, expose bearings
- Analysis: Inspection of bearings, windings, temperature sensors and encoder signal quality
- Repair: Replacement of defective bearings, cleaning of the interior, replacement of the UTSIH-B17CC encoder if necessary
- Testing & load test: functional test on the R88D-W servopack, control of current consumption, smooth running, torque behavior
- Endurance test & conclusion: continuous operation under rated torque, thermal stability test, create final report
