Servo control system and robot

A robot, wherein the robot comprises a central processor, a CAN bus and a plurality of servos, each servo comprising a servo control system, each servo control system communicating with the central processor via the CAN bus, the servo control system comprising:

• a main control module;
• and
• a driving module comprising a driving circuit and an electronic switch circuit, the driving circuit being coupled to the main control module, and the electronic switch circuit being coupled between the driving circuit and a driving motor of the servo, wherein:
• the driving circuit receives a control signal outputted by the main control module and outputs a driving signal according to the control signal, and the electronic switch circuit outputs a driving pulse to the driving motor according to the driving signal, to control the driving motor to rotate;
• wherein the driving motor is a three-phase driving motor, neutral points of three-phase windings of the three-phase driving motor are coupled together, the driving motor comprises a first terminal, a second terminal and a third terminal, the driving circuit comprises three driving units, and driving chips of the three driving units are connected to the first terminal, the second terminal and the third terminal through the electronic switch circuit respectively for powering up any two of the first terminal, the second terminal and the third terminal of the driving motor so as to control the driving motor to rotate in a forward direction or a reverse direction.
