ZFeng 900 Series 7.5Kw-T General Vector Variable Frequency Drive
The ZFeng 900 series variable frequency drive developed by our company has multiple control methods such as torque and speed. By utilizing the vector frequency conversion control technology of the frequency converter, ordinary motors can also achieve various capabilities such as stepless speed regulation, soft start and soft stop, instant start and stop, and non-stop power outage, greatly improving motor response speed, enhancing motor energy efficiency, extending equipment life, and meeting users' needs for production processes
Vector frequency drive are driving industrial control towards a more intelligent and green direction through technological iteration. Their core value lies in upgrading motor control from "simple speed regulation" to "precision motion management", becoming a key supporting technology for industrial upgrading.
Core advantages
Ultimate control accuracy:By decomposing the motor current into excitation current and torque current, decoupling control of magnetic field and torque is achieved, and the speed/torque control accuracy can reach ± 0.05%, far exceeding the ± 2% -5% of traditional V/F control frequency converters.
Efficient and energy-saving: Adjust the output voltage and frequency in real-time according to the load, so that the motor always runs at the optimal efficiency point.
Low speed and high torque output: Output 150% of the rated torque during 0Hz, solving the problem of insufficient low-frequency torque in ordinary frequency converters; When lifting heavy loads with a crane, there is no need to configure a hydraulic coupling, and a soft start can be made directly to reduce mechanical impact.
Ultra wide speed regulation range: Speed ratio 1:1000, seamless switching from 0.1rpm to rated speed, suitable for low-speed winding and high-speed rewinding processes of textile winding machines.
Selection suggestions
Light load continuous operation: For ordinary fans, an economical V/F control frequency converter can be selected.
Heavy duty/high-precision scenarios: such as injection molding machines and CNC machine tools, prioritize models that support closed-loop vector control.
Special environment: ATEX certified products are required for explosion-proof applications, and independent heat dissipation modules are required for high-temperature environments.
Installation and maintenance recommendations
Environmental requirements: dry, ventilated, avoid direct sunlight, recommended working temperature -10 ℃~50 ℃.
Wiring specifications: Strictly distinguish between the main circuit and the control circuit, with a grounding resistance of ≤ 4 Ω.
Regular maintenance: Clean the dust accumulation on the heat sink every 6 months, check the status of the capacitor, and backup parameter settings.
