5. Top manufacturer of AC drive in China! Creative Technology, Service leading! Hoister systems With the variable frequency technology to updated the hoister system to achieve constant torque control under full frequency range( 0 to 50Hz/60Hz), also can overcome the defects of traditional AC wound rotor with series resistor speed adjusting system. Dynamic braking with resistor solution with cheaper cost and energy feedback solution with remarkable energy both can be consider to use for regenerated energy issue. For the safety consideration, the hydraulic braking system should be reserved, and integrated with VFD braking function to achieve better control. With the PWM control and IGBT rectifying function to realized the dual direction control for rectifying and energy feedback, the power factor will be near to 1 and to realized the true four- quadrant running. Application cases showing Conveyor belt. There are a lot of benefit we can get when using Veichi medium voltage for conveyor belt such as soft start, soft stop, reduce the mechanical impact in effectively and extend the service life span. With the mast –slave control technology of veichi MV drive, the output torque and DC bus voltage of mast-slave of drive can be make the same almost via the output torque control of drive. The tolerance of output torque of mast- slave will be within ±1% when the system is running stability. Advantage of using with VFD 1.Achieve soft start of belt system 2.Power balance of belt system with multi- motors 3.Reduce the tension of belt 4.Reduce the mechanical impact 5.Mini the maintenance of system 6.Smooth start, large torque output, no impact current, start with heavy load is available. 7.Energy saving.

6. Top manufacturer of AC drive in China! Creative Technology, Service leading! Oil extraction machine The law of motion of oil extraction machine will adapt the oil well change condition with variable frequency drive to improve the efficiency of system and increase the production. The advantage of oil extraction with VFD retrofitting. 1.Increasing the power factor, ( from 0.25 ∽ 0.5 to 0.9),. 2.Reduce the current of power supply, so it means reduce the load of grid and transformer. 3.Speed regulating in dynamic to achieve the energy saving and increasing production. 4.Reduce the impact for gear box with soft starting to avoid big mechanical impact and extend the service lift span of machine. Counter-rotating fan Adjusting the speed of fan with AC60 medium voltage VFD to change the flow of fan to meet the process requirement and enable to energy saving and process optimize. Using the VFD is the best solution for fans application, because it is not only the stepless speed regulating is available, but also can achieve the constant flow control with close loop.
