We are a dedicated Servo Motor Department.
Here at ACT our technicians are artfully trained to diagnose and repair each servo motor using proprietary techniques to ensure the proper operation of the motor according to the manufacturer’s specifications. Each motor goes through a thorough testing procedure to determine the motor malfunction with complete teardown, repair, and post-test to bring the motor operation up to proper specs. Each repair also includes a complete evaluation report outlining the condition of the motor upon arrival with motor tests performed to determine the condition of the rotor magnets, stator windings, and bearings.
Winding tests are performed using the PdMA hardware and software tools. Motor CEMF and brake torque is also tested and compared with known data. The feedback device is tested using proprietary Mitchell hardware and software equipment to evaluate the condition of the feedback device(s). The results of those tests, any pertinent datasheets and daily job notes pertinent to the repair, along with numerous other data are then included with the repair.
In-Depth Testing Process
- We utilize the Mitchell Equipment diagnostic and repair system
- Initial back-drive testing alignment verification
- Verify breakdown condition under "real life" full load conditions
- Record test data including: winding waveforms, feedback signals, reverse generated voltage readings, shaft and encoder alignment data
Quality Repair Method
- All bearings are replaced with NEW bearings
- We verify feedback devices to OEM specification
- In-house machining center that can re-machine the end bells, shaft and motor housings
