At the beginning of the new year, the Ministry of Industry and Information Technology (MIIT) announced the "List of the First Batch of Advanced and Applicable Technologies", and "High-efficiency Energy-saving Permanent Magnet Flexible Transmission Equipment and Permanent Magnet Low-speed Direct-drive Motor" from Anhui VOOFU Permanent Magnet Technology Co., Ltd. were prominently listed.

Voofu Permanent Magnet WF-XF Classifier Direct-drive Permanent Magnet Motor is essentially an engineering achievement combining permanent magnet synchronous motor and direct-drive design. Its working principle can be summarized into three steps: magnetic field generation, torque production and direct drive. Step 1: Permanent magnet generates magnetic field. The motor creates its own magnetic field with no external excitation required. The rotor surface is embedded with neodymium-iron-boron (NdFeB), a rare-earth permanent magnet material featuring high magnetic energy product and high coercivity, which produces a constant magnetic field permanently. This is fundamentally different from conventional asynchronous motors that rely on induced current in the stator to generate magnetic fields. It delivers more stable magnetic field, lower energy consumption and faster response.

Voofu Permanent Magnet Direct-drive Motor for Air-cooled Island (WF-KD Series) is essentially an engineering masterpiece combining permanent magnet synchronous motor and direct-drive design. Its core working principle can be summarized in three key points: magnetic field, rotation and direct drive. Magnetic field establishment: Permanent magnets replace excitation current. The rotor core is embedded with rare-earth permanent magnet materials featuring high magnetic energy product and high coercivity, such as N45UH neodymium-iron-boron (NdFeB). Once magnetized, the permanent magnets generate a constant magnetic field permanently with no need for electric excitation. This is completely different from conventional asynchronous motors that rely on induced current in the stator to build magnetic fields. It delivers a more stable magnetic field, lower energy consumption and faster response.

Cooling tower fans run around the clock with substantial energy consumption. Common long-standing problems plaguing numerous factories include reducer oil seepage, vibration and noise, as well as frequent maintenance. These issues are now completely resolved by an innovative technology. Developed independently by Anhui Voofu Permanent Magnet Technology, the direct-drive permanent magnet motor for cooling towers redefines the driving solution for cooling tower fans, featuring Class 1 energy efficiency and maintenance-free performance.

A golden rule in energy-saving retrofitting of industrial motors has been proven by an increasing number of enterprises: eliminating reducers and adopting direct drive for loads is the ultimate solution. Developed independently by Voofu Permanent Magnet Technology, our low-speed high-torque direct-drive permanent magnet motors fully embody this philosophy. Rather than making minor modifications to conventional motors, they fundamentally restructure the "motor-transmission-load" system. The direct-drive technology redefines the efficiency limit of industrial power systems.
