The servo system is a general term for the equipment that enables the system terminal execution structure to implement dimensions including displacement, rotation speed and torque according to the control instruction.
It consists of a controller at the control level, a servo drive at the drive level, and a servo motor at the execution level, supplemented by an encoder.
It determines the accuracy, control speed and stability of automation machinery and is therefore the core of industrial automation equipment.
There are currently two classification methods for servo systems, which are classified according to system power and end actuator types.
According to the power size, it can be divided into small servo, medium servo and large servo system.
Small servo usually refers to products with power less than 1KW, mainly used in small machinery such as industrial robots, electronic manufacturing, textile packaging equipment, etc; Medium servo power range in 1-7.
5KW, mostly used in milling machines, injection molding machines and other fields; The power of the large servo system is greater than 7.
5KW, mainly used to drive heavy mechanical equipment.
According to the current analysis of servo market sales, small servo applications have increased rapidly, accounting for 45%, mainly due to the rapid rise of 3C industry in recent years;
Medium servo has a market size of about 37% due to the sluggish manufacturing industry of transmission equipment such as machine tool industry in recent years;
The proportion of large servo systems is relatively stable, at about 18%.
