Servo motors primarily rely on pulses for positioning. When a servo motor receives one pulse, it can be said that the displacement is achieved by rotating the angle corresponding to one pulse. Because the servo motor itself has the function of sending pulses, when the servo motor rotates its own angle, it will send the number of pulses. In this way, the pulses received by the servo motor will be echoed or referred to as a closed loop. In this way, the system knows how many pulses have been sent. The servo motor receives how many pulses at the same time and thus controls the rotation of the motor to achieve a precise position down to 0.001mm.
The structure of the DC servo motor is the same as that of the general DC motor, but it is thin and long, which can reduce the moment of inertia. The excitation windings and armature are powered by two separate power supplies. There are also permanent magnets. In other words, the magnetic pole is a permanent magnet. Armature operation is usually used. In other words, the excitation voltage f is stable and the set magnetic velocity is stable, and the control voltage Uc is added to the armature. The difference is that the resistance of the armature is large, and the mechanical properties are smooth and linear (high resistance, weak magnetic field start, direct start).
Mechanical characteristic curves of DC servo motors at different operating voltages (Uc is the nominal operating voltage). When the magnetic flux is stable at a specific load torque, the motor speed increases when the armature voltage increases, and conversely, when the armature voltage decreases, the motor speed decreases. If Uc=0, the motor stops immediately. To make the motor rotate, change the polarity of the armature voltage.
Power Supply Method:
Independent power supply. The excitation winding and armature winding are powered by two separate power supplies.
How to control:
1. Armature Control (Main)
2. Pole manipulation (reduce use).

OTC robot contacts need to be replaced
Contacts are one of the items that often replace welding materials. During this time, the contact fixes the direction of the wire, and since the instantaneous current that moves when the arc is closed after welding is too simple to melt the contact outlet, it must have a role. The wire and contacts have been welded together, so that the welding can no longer be performed ...

Advantages of OTC welding robots in electrode grinding
Generally speaking, welding robots need to carry out electrode grinding operations after long-term operation. This is due to the fact that after the robot has been welded repeatedly, the shape of the electrode tip may change, that is, the electrode will be worn, resulting in the welding quality of the robot.
