Table fans, pedestal fans, tower fans and air circulators repeatedly perform horizontal oscillation, vertical movement, angle holding and start-stop operation. Long-term wear can cause reduced angle, abnormal noise, jamming and wiring failure. An automated oscillation life tester provides repeatable endurance and fault monitoring.

1. System Configuration

A typical system includes a multi-station frame, independent power channels, adjustable fixtures, angle sensors, PLC and HMI. The fixture must hold the fan base without restricting normal movement.

2. Test Program

1. Record initial angle, voltage, operating mode and noise;
2. Set horizontal or vertical motion, dwell and start-stop timing;
3. Set total cycles and inspection intervals;
4. Run trial cycles before formal endurance testing;
5. Inspect angle, noise, temperature and appearance at planned stages.

3. Fault Monitoring

Current, power, endpoint position, oscillation period and angle can be monitored. The system should stop and retain the failure cycle when endpoint signals are missing, movement time is excessive, current is abnormal or the sample becomes unstable.

4. Selection and Maintenance

Specify sample quantity, dimensions, motion direction, angle range, voltage and power monitoring requirements. LSKFT can provide single- or multi-station systems for horizontal, vertical and combined oscillation.
