A05B-2452-C900 FANUC servo mechanism is an automatic control system that makes the output controlled quantity such as position, orientation and state of an object follow arbitrary changes of the input target (or given value). Servo positioning mainly depends on pulse, basically can be understood in this way, when the servo motor receives a pulse, it will rotate the Angle corresponding to a pulse, so as to achieve displacement, because the servo motor itself has the function of sending pulses, so each rotation Angle of the servo motor will send out a corresponding number of pulses, which echoes the pulse received by the servo motor. Or closed loop, so that the system will know how many pulses are sent to the servo motor, and how many pulses are received back, so that it can be very precise control of the motor rotation, so as to achieve accurate positioning, up to 0.001mm.

Dc servo motors are divided into brushless and brushless motors. Brush motor has the advantages of low cost, simple structure, large starting torque, wide speed regulating range, easy control, need maintenance, but not convenient maintenance (carbon brush), electromagnetic interference and environmental requirements. Therefore, it can be used in cost sensitive common industrial and civil situations.
