How to measure the speed of micro gear motor?

The output torque of the micro gear motor is correlated with its speed. The torque decreases with increasing speed while increasing with decreasing speed. So how do you gauge the tiny gear motor's speed? Here is a quick explanation for you.

A crucial parameter is the micro gear motor's speed. The gear motor's application range is represented by speed. The measurement is in terms of revolutions per minute. The micro gear motor typically rotates between a few and several hundred times per minute. High-speed motors can reach hundreds of thousands to hundreds of thousands of revolutions per minute, whereas micro motors can reach thousands to tens of thousands.

There are a variety of measurement techniques for determining the speed of a small geared motor, including photoelectric, centrifugal, and flash tachometers. These speed measurement techniques are not very practical, but they can accurately measure the rotational speed of the tiny geared motor. To measure speed, the tachometer must label the micro gear motor's rotating portion, and the flash tachometer must secure the micro gear motor in a suitable location. These days, a micro motor tester can be used to measure the speed of a small gear motor, which is quite practical.
