  • Protection function
Locked-rotor protectionWhen the motor rotor and output shaft are locked, the motor lock protection function starts to work, the motor output is closed, and the motor output current is returned to Zero, the motor stops working.
Current limit functionWhen the current in the motor circuit exceeds 3.0 A, the motor will be protected and stopped.

  • Reliability test

Temperature and humidity test

(without condensation)

Motor must be left at the temperature range of -20°C to 60°C and the relative humidity range of 5% to 90% for 72 H. and then returns to room temperature 12 hours. Measurement of the rated load speed and rated load current must be conformed to standard.
Vibration test (without packing)

No error should occur after test .

Direction of vibration: front and rear, right and left, up and down.

Vibration acceleration: 9.8m/s²(sine eave) vibration

Frequency range: 50Hz~50Hz~50Hz

Repeating period: 1Min Vivrating

Time:30cycle(30min) each direction.

Vibration test (packing)
