A: A: I am afraid not. The lifetime varies a lot for different models, materials and the operating conditions like temp., humidity, duty cycle, input power, and how the motor or gear motor is coupled to the load etc. And the lifetime we normally mentioned is the time when the motor rotate without any stop and the current, speed and torque change is within +/-30% of the initial value. If you can specify the detailed requirements and working condition, we'll make our evaluation to see which one will be suitable to meet your needs.
Q: May I have a motor with 12V/5000RPM/25mm, fan/car motor or could you tell me what information I should provide to get the motor I want?
A: Normally we recommend the motors based on the size constraints like diameter, length, width, the shaft diameter, rated voltage, no load speed and stall torque or on load speed and on load torque, lifetime requirements and noise level etc. And different motors might be needed for the same application if with different design. If you can send us a picture of your sample with size information, your existing spec or the detailed requirements we mentioned above, we'll see what we can do. The more information you provide; the better for us to provide what you exactly need.
