Servo drive technology has always held a pivotal position in the field of industrial control. In recent years, thanks to the continuous efforts of scholars from around the world, servo drive-related technologies have achieved new breakthroughs. Low-power servo drives, combining high-performance permanent magnet synchronous motors (PMSMs) with advanced control theory, are now ubiquitous and rapidly developing in areas such as robotic arm control, medical equipment, and intelligent robotics. Tonghang, a professional servo drive manufacturer, has designed a cost-effective, compact, low-voltage, low-power servo drive.

Development Trends in Permanent Magnet AC Servo Drive Technology

Currently, AC servo systems are undergoing a transition from analog to digital. The widespread introduction of new power semiconductor devices, high-performance microcontrollers, and specialized servo system processors has resulted in servo product upgrades occurring almost every five years on the international market. New software algorithms are also evolving rapidly, shortening product lifecycles. A survey of servo drive products on the market and an analysis of recent servo drive technology predicts that servo drive technology will develop in the following directions

Digitalization

Advances in integrated circuit manufacturing technology and semiconductor power device technology have made full digitalization of servo drive systems possible. In recent years, a number of new high-speed microprocessors and specialized DSPs have emerged on the market. Servo control units enable the application of advanced control algorithms in permanent magnet AC servo drives. The digitization of servo drive systems not only simplifies hardware but also significantly improves system reliability and control accuracy.

Higher Performance and Multifunctionality

The use of advanced power devices reduces servo drive system power consumption, significantly improves system response speed and smoothness, and reduces operating noise. To reduce torque ripple and motor losses, the motor's back EMF needs to be made more sinusoidal. To achieve this, motor structure optimization is ongoing. Furthermore, direct drive technology is being adopted in some areas to improve servo system performance. This eliminates the mechanical transmission link between the motor and the worktable, achieving "zero transmission" and significantly enhancing the rigid coupling between the motor and the load.

The functionality of servo drive systems is also constantly expanding. Tonghang's newer servo drive controller series offer a wide range of functions, such as parameter auto-tuning, parameter memory, vibration suppression, and fault diagnosis.

Miniaturization and Integration

We offer servo drive products that incorporate both positioning and speed regulation capabilities, allowing for flexible functionality through software customization. Position or speed servo units, open or closed loop, can all be configured through software. This digitalization and integration significantly improves the integration of servo systems and reduces the size of the entire drive control system.

Universalization

For universal servo drive control systems, users can easily configure various operating modes through software and menus, including V/F control or vector control, open or closed loop control, and sensored or sensorless control, to suit different motor types and applications, without changing the overall hardware configuration, based on the specific usage environment and control target.
