Product Overview

The WF-GF Air-Cooled Low-Speed Direct-Drive Permanent Magnet Roller is a high-efficiency, energy-saving drive device developed by voofu Permanent Magnet Technology Co., Ltd. for industries such as coal, mining, ports, power, building materials, and chemical. The product integrates the permanent magnet synchronous motor directly with the roller structure, eliminating traditional reduction devices and achieving a direct connection between the motor and the load, thereby significantly improving system efficiency and reducing energy consumption and maintenance costs. Additionally, it adopts an air-cooled heat dissipation method, adapting to harsh environments such as high temperature and heavy dust.

Product Features

1. High Efficiency & Energy Saving:

Eliminates intermediate transmission components, improving transmission efficiency to over 90%, saving 20%-30% energy compared to traditional drive systems. The motor operates with high efficiency and a power factor close to 1, reducing reactive power loss and lowering grid load. Maintains high efficiency within a 25%-120% load range, with even more significant energy-saving effects under light load conditions.

2. Low Speed, High Torque:

Directly produces the low speeds required by equipment (e.g., tens to hundreds of revolutions per minute) while outputting high torque, perfectly meeting low-speed, high-torque demands. Peak torque at startup can reach over 2 times the rated torque, easily solving the problem of heavy-load starting.

3. Stable and Reliable:

The direct-drive design reduces transmission components, significantly lowering failure points and improving equipment operation stability. The motor features a high protection class (IP55 or higher), adapting to harsh environments. Bearing life reaches up to 100,000 hours, requiring only periodic lubrication, essentially achieving maintenance-free operation.

4. Intelligent Control:

Supports variable frequency speed regulation, achieving stepless speed regulation to meet speed requirements under different operating conditions. Supports multiple communication interfaces, allowing integration with central control systems for remote monitoring and fault diagnosis. Can store operating data, supporting online monitoring and data analysis.

5. Air-Cooled Heat Dissipation:

Adopts an air-cooled heat dissipation method, cooling the motor by drawing in cold air and exhausting hot air through the roller, with high heat dissipation efficiency. No oil-based cooling is required, eliminating the risk of oil leakage pollution, making the site cleaner and more environmentally friendly.

6. Compact Structure, Easy Installation:

The integrated design of the motor and roller saves installation space and facilitates installation and maintenance. Roller lagging and replacement are more convenient, reducing maintenance costs.
