What frequency converter is used for cranes?

In recent years, with the rapid development of industrial automation, as an important lifting equipment, the selection of the core control component of the crane, the frequency converter, has become the focus of the industry. This article will combine the hot topics and hot content on the entire network in the past 10 days to provide you with a detailed introduction to the types of frequency converters commonly used in cranes, performance comparisons and selection suggestions.

1. The role of crane frequency converter

The frequency converter is the core component of the crane control system. It is mainly used to adjust the speed and torque of the motor to achieve smooth start, precise speed regulation and efficient operation of the crane. Its main functions include:

1. Energy saving and consumption reduction: Reduce the waste of electric energy by adjusting the motor speed.

2. Precise control: achieve smooth start and precise positioning of the crane.

3. Protect equipment: Prevent motor overload and overheating, and extend equipment life.

2. Comparison of types and performance of commonly used frequency converters for cranes

According to the hot discussions on the entire network in the past 10 days, the frequency converters commonly used in cranes mainly include the following types:

3. Suggestions for crane inverter selection

1.Choose according to crane type: Different types of cranes have different requirements for frequency converters. For example, port cranes require special frequency converters with strong anti-interference capabilities, while small workshop cranes can choose general-purpose frequency converters.

2.Consider load characteristics: The load characteristics of the crane (such as starting torque, operating frequency, etc.) directly affect the selection of the inverter. Vector inverters are suitable for high-torque and high-precision applications, while general-purpose inverters are suitable for scenarios with lighter loads.

3.Pay attention to the brand and after-sales service: Choosing inverters from well-known brands, such as Siemens, ABB, etc., can not only ensure performance, but also obtain perfect after-sales service.

4.Energy saving and environmental protection: With the improvement of environmental protection requirements, it has become a trend to choose frequency converters with energy-saving functions. For example, frequency converters with energy regeneration can significantly reduce energy consumption.

4. Recent hot topics and industry trends

1.Application of intelligent frequency converter: Recently, many companies have launched frequency converters with AI algorithms, which can automatically adjust parameters according to the operating status of the crane to improve efficiency and safety.

2.The rise of domestic inverters: In recent years, domestic inverter brands (such as Inovance and INVT) have continuously improved in performance and reliability and gradually gained market recognition.

3.Energy-saving policies promote inverter upgrades: Many governments have introduced energy-saving policies to encourage companies to use high-efficiency inverters, further promoting innovation in inverter technology.

5. Summary

The selection of frequency converters for cranes requires comprehensive consideration of equipment type, load characteristics, brand services and energy-saving requirements. With the advancement of technology, intelligent and energy-saving frequency converters will become the mainstream in the future. I hope this article can provide a reference for your selection!
