Micro servo motors generally refer to servo motors with relatively small volume and power below 1000W.

Of course, there is no absolute standard to measure what is a micro servo, what is a small servo, and what is a large servo.

After all, the purpose of our choice of servo is to meet the needs of the project.

What are the needs of the project?

The main ones are the power, output torque, rated speed, working stability, price and so on of the motor.
First look at the volume and weight.

Since it is a micro servo motor, it must be small in size and light in weight.

On the one hand, this allows it to be integrated into more devices, and on the other hand, it is also convenient to transport.

Then there is power.

Generally, motors with higher power have higher supply voltage and current and require more components.

Limited by the small volume and weight, the power of the micro servo will not be very large, generally between several hundred watts and several thousand watts.

After all, if the power is too high, heat dissipation is also a big problem.

Micro servos do not have such a complete heat dissipation system as large servos.
Then look at the motor speed and output torque.

In terms of speed, micro servos are relatively fast, and thousands of revolutions per minute are normal.

The torque is limited by the power.

This type of servo can only output a torque of about a few Nm.

This is for most cases, and it does not mean that there are specific devices that can output a larger value.
In addition, micro-servo is relatively simple and convenient to maintain.

It is integrated with various encoders, and its motion accuracy is very high.

Various high-precision production lines, such as those that produce semiconductors, will have servos in their motion mechanisms.
