How will the drive and control systems of electric stacker develop in the future

Drive and control systems are very important for any mechanical equipment or vehicle. The same is true for electric stacker. The development of the drive and control system for electric stacker is reflected in two aspects: the drive motor and the control system. Motors are divided into DC motors, AC motors, and special new types of motors. With the development of power electronic control technology for AC motors, DC motors are gradually being replaced by AC motors and their control devices. Next, the stacker manufacturer will talk to you about the future development direction of the drive and control system of electric stacker.

In the future, the electric driving ability of electric stacker will become stronger and stronger. Modern electric forklift trucks with the advantages of no exhaust emissions, low noise, low vibration, etc., generally use computer control devices and high energy storage batteries, making the electric driving ability increasingly strong, and further improving the operating efficiency, reliability, durability, and energy-saving effect of the machinery. Secondly, the content of electronic technology is becoming higher and higher. Modern electric stacker effectively integrate computer technology, automatic control technology, and artificial intelligence technology, enabling mechanical products to continuously develop in the direction of high technological added value. Stacker manufacturer told everyone that according to incomplete statistics, the proportion of electronic components in the product structure cost of electric stacker has basically reached around 30%, while in some automatic guidance vehicles, it has reached over 80%.

Moreover, the control technology of electric stacker is becoming increasingly accurate. The power control for the operation or lifting operation of electric stackers has evolved from the use of thyristor (SCR) to metal oxide semiconductor transistors (MOSFETs) and isolated gate bipolar transistors (IGBTs), and can achieve a wide range of stepless speed regulation and regenerative braking for energy recovery. The energy consumption of the electric servo steering system is only 10% to 20% of that of the hydraulic servo steering system. The stacker manufacturer has told everyone that using microelectronic technology can achieve comprehensive self adjustment, self diagnosis, and self protection for vehicles, such as automatic monitoring of battery discharge and charging, analysis and treatment of temperature rise of motors and electronic control devices, wear of motor carbon brushes and brake shoes, position and quality of loads, and misoperation, Display the real-time accumulated operating condition parameters and various fault information in text and symbols on the instrument panel in digital or analog quantities.

The frequency of product updates for electric stacker will accelerate. At present, although there are many types of electric stackers, they are still difficult to adapt to changing needs. To this end, product development will integrate the mechanisms of various relevant or emerging disciplines, using a comprehensive and systematic perspective and the integration of computer aided design and manufacturing (CAD/CAM) approach, using new designs, new materials, and new manufacturing processes to shorten the vehicle upgrade cycle from 8 to 10 years to 3 to 4 years. The stacker manufacturer has told everyone that the productivity of flexible manufacturing methods can reach over 20 units per person per year.
