Energy Saving 24V Brushless DC Electric Motor Three Phase 8 inch
Brushless DC Motor For Stand Fan 24VDC CL.B Energy Saving Ball Bearings
Brushless DC motor uses electronic communtation instead of mechanical steering. Compared with Brush DC motor, it has long working life and eliminates mechanical steering's noise, sparks and electromagnetic interference and so on. It is of great convenience and reasoning to control motor's performance. It can be mainly divided into two parts, motor and circuit control.

- 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) |
No error should occur after test at the mimimum package test condition. 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. |
| Shock test(packaging) |
No error should occur after test at the minimum package. Drop height: 50CM Impact shock is applied 1 time for bottom surface. |
