What is a DC servo motor?

A DC servo motor is a servo motor that operates on direct current. Servomotors are motors that accurately reproduce movements in response to control signals, and are used in precision equipment. Since DC servo motors are controlled by detecting the number of revolutions and position of the motor, it is common to have a product that integrates the motor with a sensor that detects speed and position, such as an encoder or resolver. In order to rotate a DC motor, it is necessary to pass the current supplied to the motor to the rotating shaft with a part called a brush, so the brush wears due to wear and requires regular maintenance.
