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 ℃.
