‌Factory Testing Protocol for Electric Actuators‌

I. Visual & Mechanical Inspection

Visual Check‌:

Housing deformation/scratches/rust

Legible markings (model, voltage, current)

Mechanical Components‌:

Smooth operation of gears/lead screws

No abnormal wear or binding

Sealing Integrity‌:

IP65+ models: Verify gasket condition

Optional water ingress test (per IEC 60529)


II. Electrical Performance Tests

Test Method Criteria
Insulation Resistance Megohmmeter (500VDC) ≥100MΩ (terminal-to-housing)
Dielectric Strength 1.5× rated voltage (e.g., 1500VAC/1min) No breakdown/leakage
Voltage Tolerance ±10% nominal voltage (e.g., 198-242VAC) Normal startup/operation

III. Functional Verification

Travel Control‌:

Positioning accuracy: ±0.5° or ±1mm repeatability

Limit switches: Proper engagement & signal output

Feedback Signals‌:

4-20mA/0-10V correspondence (0%=4mA, 100%=20mA)

Potentiometer/encoder linearity verification

Manual Override‌:

Handwheel/clutch operational test


IV. Dynamic Performance Tests

Speed‌: Full travel time (e.g., 30s/90°)

Torque/Thrust‌:

Torque sensor validation (e.g., 50Nm nominal)

Overload Protection‌:

120% load triggering alarm/shutdown

Noise/Vibration‌:

≤0.1mm/s vibration (per ISO 10816)


V. Communication Tests (Smart Actuators)

Protocols‌: Modbus RTU/Profibus DP parameter R/W

HART/Bluetooth‌: Remote configuration verification

VI. Environmental Testing

Condition Test Standard Acceptance Criteria
-30°C to +70°C IEC 60068-2-1/2 Stable operation
85% RH IEC 60068-2-30 Insulation resistance maintained
IP65/IP67 IEC 60529 No water penetration

VII. Safety Protections

Thermal Protection‌: Auto-shutdown at overtemperature

Phase Sequence (3-phase)‌: Alarm on reversed phases

Emergency Stop‌: Immediate power cutoff via ESD


VIII. Life Testing (Sampling)

Mechanical‌: 100,000 cycles (wear assessment)

Electrical‌: Contactors/relays endurance test


Testing Equipment Recommendations‌:

Multimeter, Megohmmeter, Oscilloscope

Torque transducer, Signal generator

Environmental chamber

Batch Acceptance‌: AQL sampling per ISO 2859-1
