The invention discloses a control module for a servo motor, which is developed on the basis of a single chip microcomputer. The control module is used for realizing the precise control on the rotating speed and position of the servo motor and monitoring the working current and torque of the servo motor in real time. The control module is mainly composed of a single chip microcomputer control module, a motor driver, an optical-electricity encoder, a current and torque sensor, a storage module, an input output terminal and an Ethernet interface. The single chip microcomputer control module is mainly used for outputting a motor control signal, processing a position and speed signal collected by the optical-electricity encoder, switching the signal collected by the current and torque sensor and sending the information to the input output terminal, the storage module and the Ethernet interface, so that the display, storage and remote monitoring for the data are realized. The control module for the servo motor has the advantages of high control precision, smaller volume, safety, reliability, lower cost, and the like, and can realize the storage for the data and the remote monitoring for the working state of the motor.
