servo motor The main difference from ordinary motors is:

Servo motor positioning is more accurate with feedback. Ordinary motors do not have it, they start running when powered on.

The difference in feedback mode between servo motors and ordinary motors:

Servo motors can achieve precise control. They can rotate as much as you want them to, and they will also provide feedback to achieve a closed-loop system. The encoder will provide feedback to see if they have indeed rotated as much, thus achieving precise control.

It can hit wherever you point, and you can make it rotate at a specified speed by a specified angle/number of turns. It can be equipped with a screw to achieve precise positioning.

A regular motor starts running when powered on and stops when it runs out of power. In addition to running, if we have to say what function it has, it is forward and reverse rotation.

The structural differences between servo motors and ordinary motors:

The mechanical structure of servo motors and ordinary motors is similar in principle, both consisting of a stator and a rotor. Their main differences are mainly manifested in the blade structure and driving circuit.

The characteristic of a servo motor is that its motion direction is proportional to the voltage between the power supply, and it usually consists of an encoder, a controller, and a servo motor. Encoders can provide higher resolution to ensure precision control; The controller is the "brain" that specifies the direction, speed, and torque of the motor, responsible for converting the control signals sent by the driver into corresponding motor motion commands. The driver provides power and is a device that connects the motor and power supply. It can accurately deliver the required electrical energy to the motor based on control signals.

Ordinary motors only consist of the power supply part and the motor body, and the motor speed or torque can be further determined based on the magnitude of the input voltage. Normally, ordinary motors use open circuits, and their operating speed depends on the voltage, so the choice of controller is not as important as servo motors.
