Product Overview
The WF-TT Tubular Permanent Magnet Adjustable Speed Drive is a high-efficiency, energy-saving speed control device independently developed by Anhui voofu Permanent Magnet Technology Co., Ltd., specifically designed to meet the speed regulation needs of high-power motor systems. The product uses rare earth permanent magnets and alloy conductors to transmit torque through an air gap, achieving non-contact torque transmission between the motor and the load. It features a wide speed regulation range, significant energy-saving effects, and stable, reliable operation.
Product Features
1. High Efficiency & Energy Saving:
The WF-TT Tubular Permanent Magnet Adjustable Speed Drive achieves stepless speed regulation by adjusting the air gap between the permanent magnet rotor and the conductor rotor, with a speed regulation range of 0-97%, and a power saving rate typically reaching 20%-50%, and in some application scenarios even exceeding 70%.
During speed regulation, the motor speed remains constant, avoiding the issues of increased harmonic heating and deteriorated heat dissipation caused by speed reduction, thereby improving the overall system energy efficiency.
2. Stable and Reliable Operation:
The product features a tubular structure design, which is simple, reduces vibration and noise, and improves the stability of the transmission system.
The permanent magnet material maintains strong magnetic field characteristics even under harsh ambient temperatures, ensuring normal operation at extreme temperatures of ±100°C.
The non-contact torque transmission method isolates vibration, reduces mechanical wear, and extends the equipment service life.
3. Strong Adaptability:
The WF-TT Tubular Permanent Magnet Adjustable Speed Drive is suitable for various harsh environments, including those with large grid voltage fluctuations, severe harmonics, flammable and explosive conditions, humidity, and dust.
In flammable and explosive environments, as a mechanical speed control device, the product does not generate sparks or static electricity, ensuring safe and reliable use.
For high-dust environments such as cement plants and mines, its minimal air gap design effectively prevents dust ingress, and it can be cleaned with high-pressure water jets, making maintenance simple.
4. Low Maintenance Cost:
The product has a design life of over 25 years and is virtually maintenance-free, requiring only periodic lubrication.
It reduces downtime caused by equipment failures, lowering both maintenance and operating costs.
5. Green & Environmental Friendly:
The WF-TT Tubular Permanent Magnet Adjustable Speed Drive generates no harmonics or electromagnetic interference during operation, complying with national power quality standards.
It reduces electricity consumption and pollutant emissions, contributing to green production and sustainable development.
Application Fields
The WF-TT Tubular Permanent Magnet Adjustable Speed Drive is widely used in energy-saving retrofit projects for high-power motors in many fields such as power, metallurgy, chemical, cement, coal, steel, and military industries. Specific application scenarios include:
Fan Speed Regulation: Such as cooling tower fans, boiler induced draft fans, etc., achieving precise airflow control through speed regulation to improve energy efficiency.
Pump Speed Regulation: Such as circulating water pumps, feed pumps, etc., adjusting flow according to actual demand to reduce energy waste.
Other Centrifugal Loads: Such as compressors, mills, etc., achieving optimized load operation through speed regulation to improve production efficiency.
