I am afraid not. The lifetime varies a lot for different Models, materials, and 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 rotates 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 conditions, we’ll make our evaluation to see which one will be suitable to meet your needs.
