Product Overview

The WF-LM Vertical Mill Direct-Drive Permanent Magnet Motor is a high-efficiency, energy-saving drive device developed by voofu Permanent Magnet Technology Co., Ltd. for industries such as mining, power, building materials, and chemical. The product is specifically designed for vertical roller mills, directly driving the grinding table through permanent magnets, eliminating intermediate transmission components such as gearboxes and couplings in traditional drive systems, achieving a direct connection between the motor and the load, thereby significantly improving system efficiency and reducing energy consumption and maintenance costs.

Product Features

1. High Efficiency & Energy Saving:

Eliminates intermediate transmission components, improving transmission efficiency to over 95%, saving 15%-20% energy compared to traditional drive systems. The motor has high efficiency with 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 the low-speed, high-torque demands of equipment such as vertical mills. Peak torque at startup can reach twice 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 (IP67), adapting to harsh environments with high temperature, high humidity, and heavy dust. 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 such as CAN, RS485, and PROFIBUS-DP, allowing integration with central control systems for remote monitoring and fault diagnosis. Can store operating data from the last three months, supporting online monitoring and data analysis.

5. Environmentally Friendly:

Eliminates transmission devices such as gearboxes, ending the problem of oil leakage pollution, making the site cleaner and more environmentally friendly. Low-noise and low-vibration design improves the working environment.
