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.
