Product Overview
The WF-TD Horizontal Air-Cooled Double-Supported Permanent Magnet Adjustable Speed Drive is a high-efficiency, energy-saving speed control device developed by voofu Permanent Magnet Technology for small to medium-power motor systems (typically suitable for centrifugal pumps and fans below 630kW). The product adopts permanent magnet drive technology and achieves a soft connection between the motor and the load through non-contact torque transmission. It features a wide speed regulation range, significant energy-saving effects, and stable, reliable operation. It is widely used in energy-saving retrofits of centrifugal loads such as fans and pumps in industries including power, metallurgy, chemical, cement, and coal.
Product Features
1. High Efficiency & Energy Saving
Wide Speed Regulation Range: Supports 30-97% stepless speed regulation, allowing precise adjustment of load speed according to actual demand, avoiding the "big horse pulling a small cart" phenomenon, with a power saving rate typically reaching 20%-50%.
Soft Start Function: The motor starts under no load, and the load accelerates smoothly by adjusting the air gap, reducing starting current surge and extending the life of both motor and load.
No Harmonic Interference: Pure mechanical speed regulation without power electronic components, avoiding harmonic pollution to the power grid and reducing reactive power loss.
2. Structural Advantages
Double-Supported Design: Adopts a double-bearing support structure, enhancing equipment rigidity, reducing vibration and noise, and improving operational stability.
Air-Cooled Heat Dissipation: Uses convective heat dissipation through cooling fins on the conductor rotor surface, requiring no external cooling system, suitable for poorly ventilated areas.
Compact and Lightweight: Tubular structure design, small in size and light in weight, facilitating on-site layout and maintenance.
3. Strong Environmental Adaptability
Withstands Harsh Environments: Operates stably in extreme temperatures from -40°C to +100°C, suitable for high-dust, humid, flammable and explosive locations.
Explosion-Proof Performance: The main power part transmits torque without friction, generating no sparks or static electricity, suitable for applications with high explosion-proof requirements such as coal mines, oil fields, and chemical plants.
High Reliability: No mechanical connection design, isolates vibration, reduces mechanical wear, and extends equipment service life.
4. Low Maintenance Cost
Maintenance-Free Design: No bearings or wear parts, requiring only periodic air gap inspection and lubrication, with a design life exceeding 25 years.
Low Failure Rate: Non-contact transmission isolates vibration, reduces mechanical stress, and lowers the failure rate of various transmission system components (such as bearings, seals, etc.).
Application Fields
The WF-TD Horizontal Air-Cooled Double-Supported Permanent Magnet Adjustable Speed Drive is widely used in the following scenarios:
1. Power Industry: Boiler induced draft fans, primary air fans, circulating water pumps, etc.
2. Metallurgical Industry: Blast furnace blowers, dust removal fans, cooling water pumps, etc.
3. Chemical Industry: Compressors, mixers, circulating pumps, etc.
4. Cement Industry: Kiln head and kiln tail fans, raw mill fans, circulating water pumps, etc.
5. Municipal Water Supply: Urban water supply pumping stations, aeration fans in wastewater treatment plants, etc.
