1. Rapidity, the time from obtaining the command signal to the working state required by the completion of the instruction should be short. The shorter the time of echoing the command signal, the higher the sensitivity of the electric servo system, and the better the fast response function, generally the size of the electromechanical moment constant of the servo motor is used to illustrate the fast response function of the servo motor.
2. The starting torque inertia ratio is large, and in the case of driving the load, the starting torque of the servo motor of the robot is required to be large and the moment of inertia is small.
3. The continuity and linearity of the control characteristics, with the change of the control signal, the speed of the motor can be continuously changed, and sometimes the speed needs to be proportional or approximately proportional to the control signal.
4. The speed regulation scale is wide, and it can be used in the speed regulation scale of 1:1000-10000.
5. Small size, small mass and short axial size.
6. Able to withstand harsh operating conditions.
It can perform very frequent forward and reverse and acceleration and deceleration operations, and can withstand overload for a short period of time.
Now, because AC and DC servo motors with high starting torque, large torque and low inertia are widely used in industrial robots, most of the industrial robots with a general load of 1000N (equivalent to 100kgf) choose the electric servo drive system. The selected joint drive motors are mainly AC servo motors, stepper motors and DC servo motors. Among them, communication servo motors, DC servo motors, and direct drive motors (DD) are all selected for position closed-loop control, which are generally used in high-precision and high-speed robot drive systems. The stepper motor drive system is mostly suitable for small simple robot open-loop systems that do not require high precision and speed. Communication servo motors have been widely used in flammable and explosive environments because of the electronic commutation and no reversing sparks. The power scale of the robot joint drive motor is generally 0.1-10kW.

The way to reduce spatter – OTC welder
1. Adjust the arc voltage
If the settings are incorrect, the voltage setting will significantly add to the spatter. The low voltage setting can cause spatter as the wire is repeatedly short-circuited in the weld pool, resulting in a small burst at the wire tip.
This short circuit is normal for short arc MIG welding, but ...
