Variable-frequency drives, or VFDs, are a means of controlling the speed of an AC motor, typically an AC induction motor. It does so by varying the frequency of the power source.

VFDs operate by switching their output devices, which can be transistors, IGBTs, or thyristors, on and off. VFDs can be either constant voltage or constant current. Constant voltage types are the most common type of VFD. It uses pulse width modulation to control both the frequency and the voltage applied to the load.

Energy Conservation of variable frequency drives (VFD) systems If an AC-motor application that does not need to run at full speed, then you can reduce your energy costs by controlling the motor with variable speed. Energy savings with variable torque distribution can be significant, often pays the cost of the VFD in a few months. In variable torque applications, the torque required varies roughly with the square of the speed and power demand varies roughly with the cube of speed, resulting in a higher power reduction for a small reduction in speed. The engine consumes only 25% of energy compared to 50% rate is 100% speed. This is known as affinity laws, which define the relationships described between speed, flow, torque and power

VTdrive - The China's Best VFDs
Beyond your expectations!

History

Based on HUAWEI&EMERSON twenty years of experience and in depth know-how, in addition to an organisation strongly oriented towards customer needs and constant technological innovation, have enabled VTdrive to become a leader in the sector of automation for industrial process control.

The story started in 1996, HUAWEI beginning research China own brand Variable Frequency Drive. At that time, the China VFD market was under foreign brands control. HUAWEI was filled with great enthusiasm and historical mission setted up the largest R&D center for VFD in China. Mr. Qiu, our General manager, once had the privilege as a member of the excellent R&D team in HUAWEI. Depends on powerful economic and technical efficiency HUAWEI VFD got good reputation and grabbed big market share in the years that followed. The success of HUAWEI catched EMERSON attention.

After merged Control Techniques in 1995, EMERSON moved their interest to the China biggest VFD manufacturer HUAWEI. In the meantime, HUAWEI also have had mind to sell VFD division because that wasn't its core business. They have had almost one year long negotiations. In 2002, they finally clinched a deal. EMERSON took over HUAWEI VFD division, and Mr. Qiu became Chief Technical Officer of EMERSON CHINA.

2006 is a milestone of VTdrive, Mr. Qiu and his old unit left EMERSON and established VTdrive in Shenzhen.They work together for one dream that developing the China's best VFD. VTdrive was born with excellent innovation ability and great commission.It is lifeful and fast developing. The most experienced R&D team be the first developed torque-vector control frequency inverter and servo-featured frequency inverter in China and VTdrive has achieved great success rapidly.

Today VTdrive is a National High-tech enterprise, has own The Most Competitive Brands prize, Champions of National Hybrid Electric Vehicle competition and one of Top Ten Variable Frequency Drives Enterprises in China. She with around 150 R&D staff, 10% profit be used in R&D every year, own more than 320 patents, products be exported to over 60 countries and regions, growth rate more than 20% yearly.
