    Motor relaibility determination

    I would like to perform accelerated life testing on stepper motors (several sizes), also AC and DC motors to try to understand the expected operational life of each. Are there accelearation factors for (temperature, humidity, vibration) that apply to this type of device? Any suggestions...
