As a high-performance motor control device, vector frequency
converters have multiple core advantages.
Ultimate control accuracy, with an error of less than 0.5%
Vector control technology: By decomposing the motor current into
excitation current and torque current, decoupling control of
magnetic field and torque is achieved. The speed/torque control
accuracy can reach ± 0.05%, far exceeding the ± 2% -5% of
traditional V/F control frequency converters.
Application scenarios: CNC machine tool spindle control, precision
conveyor belt positioning, laser cutting equipment, ensuring that
machining size errors are controlled at the micrometer level.
Dynamic response speed increased by more than 10 times
Millisecond level response: Real time monitoring of motor rotor
position and current parameters, with response time reduced from
hundreds of milliseconds for ordinary frequency converters to 5-10
milliseconds.
Case comparison: When the elevator load suddenly changes, a regular
frequency converter needs 0.3 seconds to adjust the torque, while a
vector frequency converter can complete compensation within 50
milliseconds to avoid car shaking.
Energy saving effect up to 30% -50%
Intelligent power matching: Adjust the output voltage and frequency
in real time according to the load, so that the motor always runs
at the optimal efficiency point.
Typical scenario: In the central air conditioning water circulation
system, when the room temperature meets the standard, the water
pump speed is automatically reduced, and a single device can save
about 120000 kWh of electricity per year.
Low speed and high torque output, breaking through traditional
limitations
Zero speed full torque: It can output 150% -200% rated torque at
0Hz, solving the problem of insufficient low-frequency torque in
ordinary frequency converters.
Industrial value: When lifting heavy loads, cranes do not need to
be equipped with hydraulic couplings, and can be started directly
with soft start, reducing mechanical impact.
Ultra wide speed regulation range, covering all operating
conditions requirements
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.
Multiple protections extend equipment lifespan
Intelligent monitoring: Built in 12 protection functions including
overcurrent, overvoltage, phase loss, overheating, etc., reducing
the failure rate by 60%.
Maintenance cost: By using predictive maintenance algorithms,
potential hazards such as insufficient bearing lubrication can be
alerted 30 days in advance.
Deep adaptation to complex industrial scenarios
Multi motor collaboration: supports synchronous control of multiple
drying cylinders in paper machines, with tension fluctuations
controlled within ± 1%.
Extreme environment: In the mining crusher, vector control is used
to compensate for voltage fluctuations in the power grid and
operate stably in a low temperature environment of -20 ℃.
