Servo Motor Electric servo system
Advantages of Servomotors
1, precision: to achieve the location, speed and torque of the closed-loop control; to overcome the stepping motor out of step problems;
2, speed: high-speed performance is good, the general rated speed can reach 2000 to 3000 rpm;
3, adaptability: anti-overload ability, can withstand three times the rated torque of the load, the instantaneous load fluctuations and the requirements of the fast start of the occasion is particularly applicable;
4, stable: low-speed operation is smooth, low-speed operation will not produce similar to stepper motor stepping operation. Suitable for high-speed response requirements of the occasion;
5, Timeliness: motor acceleration and deceleration of the dynamic corresponding time is short, usually within tens of milliseconds;
6, comfort: heat and noise significantly reduced
Servo motor applications are too much. As long as there is a power source, and the accuracy of the general requirements may be related to the servo motor. Such as: machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, automated production lines, such as process accuracy, processing efficiency and reliability of the work requirements of relatively high equipment motor In order to improve efficiency, servo motors are generally colored Metal to do worm gear, worm is used hard steel. As a result of sliding friction transmission, the operation will produce more heat, so that the servo motor parts and seals between the thermal expansion of the difference, so that the formation of gaps in the mating surface, lubricating oil due to the temperature rise and thinning, easy to cause leakage The Device, it is strictly prohibited with a hammer and other hitting, to prevent axial or radial force is too large damage to the bearing or gear. Be sure to tighten the device bolts and then tighten the tightening bolts. Before the device, the motor input shaft, positioning the boss and reducer connection parts of the anti-rust oil with gasoline or zinc sodium water wipe net. Its purpose is to ensure the tightness of the connection and the flexibility of operation and to prevent unwanted wear.
So far, high-performance electric servo system mostly use permanent magnet synchronous AC servo motor, control the drive to use fast, accurate positioning of all-digital position servo system. Since the 1980s, with the development of integrated circuits, power electronics technology and AC variable speed drive technology, permanent magnet AC servo drive technology has been outstanding development, the famous electrical manufacturers have introduced their own AC servo motor and servo drive series Products are not perfect and updated from time to time. AC servo system has become the contemporary high-performance servo system, the main direction of development, so that the original DC servo is facing out of the crisis.
