As a high-performance motor control device, vector frequency converters have multiple core advantages.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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 ℃.
