Although this work has been ongoing, it still requires continued enhancement. This includes improvements to the motor itself, such as enhanced permanent magnet material performance and better magnetic installation structure design, as well as the optimization of the drive system's efficiency, which encompasses the optimization of inverter drive circuits, acceleration/deceleration movements, regenerative braking and energy feedback, and improved cooling methods.
Direct Drive
Huizhou Servo Repair Factory explains that direct drives include servo drives for turntables with disk motors and linear servo drives with linear motors. By eliminating intermediate transmission errors, these systems achieve high-speed operation and precise positioning. The easily adjustable shape of linear motors allows various devices utilizing linear linear mechanisms to be miniaturized and lightweight.
High-speed, high-precision, high-performance
By incorporating higher precision encoders (at the million pulse per revolution level), higher sampling accuracy and data bits, faster DSPs, high-performance rotating and linear motors without cogging effect, and leveraging modern control strategies such as adaptive and AI, we continuously enhance the performance standards of our servo systems.
Integration and Consolidation
Vertical integration of motors, feedback, control, drives, and communication is a developing trend in current low-power servo systems. Sometimes, we refer to such motors that integrate drives and communication as intelligent motors. Occasionally, we call the drives that integrate motion control and communication intelligent servo drives. The integration of motors, drives, and control brings the three components closer together from design, manufacturing, to operation and maintenance. However, this approach faces greater technical challenges (such as reliability) and challenges to engineers' usage habits, making it difficult to become mainstream and a small, distinctive part of the entire servo market.
Generalization
Huizhou Server Repair Factory introduces the general-purpose driver, which is equipped with a large number of parameters and rich menu functions. It allows users to easily set up in five operating modes—V/F control, open-loop vector control without speed sensors, closed-loop flux vector control, permanent magnet brushless AC servo motor control, and regenerative units—without altering the hardware configuration. Suitable for various applications, it can drive different types of motors, such as asynchronous motors, permanent magnet synchronous motors, brushless DC motors, stepper motors, and can also accommodate various sensor types, even without position sensors.
Huizhou Server Repair Factory Analysis: The system can utilize the feedback configured within the motor itself to form a semi-closed-loop control system, or it can interface with external position, speed, or torque sensors to create a high-precision full-closed-loop control system.
