Brushless DC motor life expectancy
Brushless DC motor life expectancy
(OP)
Can anyone recommend me a way to calculate Mean Time Between Repair (MTBF) of BLDC motor. Is there a way of estimating it without the help of the manufacturer?
The engine specs are:
2 poles 21 winding
inrunner
1:4.4 transmission
76.1 mm length
27.6 mm diameter
15 Ampere
15 volt
max rpm 60k
appreciate anyone's help

The environmental conditions are key to motor life. Can dust get into the bearings? Is the motor temperature cycled causing differential thermal expansion stresses?

sreid is right the environmental conditions are key to motor life. Dust and durt can kill a motor life by increasing the winding temp and contaminating the brg grease.
The best thing to do is to call the manufacturer and talk to them about it. They will want to know what the room temp, load that you are running and type of service (hours per day running).
