Every family will have some old appliances. If it is handled improperly, it will not only pollute the environment, but also make the resources not be used for the most reasonable use. In order to standardize the recycling of waste electrical and electronic products, save resources, protect the environment, and establish a recycling system for discarded electrical and electronic products compatible with China's economic, social, and ecological development, the Ministry of Commerce has drafted the “Administrative Measures on the Recycling of Waste Electrical and Electronic Products (Consultation Draft)†》, now seek advice from the community. The public can provide feedback through the following ways and methods: 1. Log on to the China Legal Information Network, and go to the left side of the home page to submit comments on the “Opinion and Regulations Draft Solicitation Systemâ€.
2. Log on to the website of the Ministry of Commerce and go to “Request for Comments†and click on “Management Measures for the Recycling of Waste Electrical and Electronic Products (Consultation Draft)†for comments.
3. Email: tf_liutong@mofcom.gov.cn.
4. Communication address: Department of Commerce and Industry, No. 2 East Chang'an Avenue, Beijing, Zip Code: 100731.
The deadline for comments is January 16, 2013.

These keywords represent critical components and applications within the electrical and industrial sector. Here's how they can be classified:
-
Frequency Converter: A frequency converter is a device that converts the frequency of an alternating current (AC) to match the requirement of a particular electrical device or system. This allows equipment designed for specific frequency to operate in regions where the electrical supply has a different frequency. For example, a frequency converter can be used to allow a device designed for a 60Hz supply to operate in a region with a 50Hz supply.
-
Variable Frequency Drive (VFD): A VFD is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. VFDs have significant applications in industrial systems and machinery, where they allow for precise control of motor speed and torque, leading to increased efficiency and longevity of equipment.
-
Pumps, Fans, Conveyors: These are common applications of motors controlled by VFDs. The variable speed provided by the VFD allows these systems to operate more efficiently and adjust to the specific demands of their task. For instance, a pump's flow can be controlled more accurately, fans can be speed adjusted according to the cooling requirement, and conveyor speed can be precisely managed based on the production line's needs.
-
Phase Motor: A phase motor refers to the type of electric motor, which operates based on the phase of the power supply. The most common types are single-phase motors and three-phase motors. Single-phase motors are usually found in lower power applications like household appliances, while three-phase motors are used in higher power applications, often in industrial settings. These motors can be controlled using VFDs for enhanced performance and efficiency.
These components play significant roles in various industries and are essential for efficient operation in many modern systems. The use of VFDs and phase motors, in particular, has revolutionized the way we control and optimize industrial processes, leading to substantial improvements in energy efficiency and system longevity.
