Why do high power dc servo motor controller is also called low pressure servo motor controller

by:Hoprio     2020-07-21

the dc servo motor controller is why not the same as ac servo motor controller? Because if it is a high power ac servo motor controller, the corresponding motor controller is also with high pressure, and even the high power dc servo motor controller can use the low voltage. Therefore, the high power dc servo motor controller is also called low pressure servo motor controller. The advantage of high power dc servo motor controller are: small volume, light weight, the output is big, fast response, high speed, small inertia, the rotation smooth, stable torque. Easy to implement intelligent and flexible its electronic commutation, can square wave or sine wave phase commutation. There is no loss of carbon brush and maintenance-free motor controller, high efficiency, low operating temperature low noise, electromagnetic radiation is very small, long life, can be used for all kinds of environment. Can be used in spark machine, the machine hand, precise machine, etc. , at the same time can be added with reducer, machinery and equipment with reliable accuracy and high torque. Although the scope of its power and ac servo motor controller, power can be done is very big, big inertia, the highest speed is low, speed decreases with the increase of power and uniform, suitable for low speed running smoothly. But the disadvantages of the ac servo motor controller is to control more complex, need to adjust PID parameters on site and determine the drive parameters, and need more attachment to support its operation work. High power dc servo motor controller can be used in low voltage equipments, it is very convenient for some low voltage equipment use demand, so than ac servo motor controller has become more and more popular. High power dc servo motor controller compared with the application field of ac servo motor controller both dc servo motor controller used in all kinds of digital control system of actuator drive and requires precise control of constant speed or requires precise control speed change curve of driving. As a result of the dc servo motor has both ac motor has simple structure, reliable operation, easy maintenance and a series of advantages, and the operation of the dc motor with high efficiency, no excitation loss and speed control performance is good, so in the various fields of national economy, such as medical equipment, instrument, chemical industry, textile, becoming increasingly prevalent in, and the application of household electrical appliances, etc. Whatever the position, speed and torque control accuracy is high, can using ac servo motor controller. Such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robot, electronic, pharmaceutical, financial instruments, automatic production line, etc. Because servo multi-purpose in position, speed control, so servo is also known as motion control. High power dc servo motor controller of many application areas, such as CNC machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robot, automatic production line, etc. , the normal operation of the servo motor controller, leave the good performance, mechanical and electrical equipment co. , LTD is specialized in the supply of normal operation of high power dc servo motor controller.
