G4.0KW-5.5KW Intelligent Speed Regulating Inverter
Product Description
The inverter modulation method adopts optimized space voltage vector SVPWM modulation, which can effectively improve the operating efficiency and control accuracy of the motor. SVPWM modulation optimizes the use of voltage vectors, reduces the generation of harmonics while ensuring the output voltage, thereby improving the operating performance of the motor. This modulation method is particularly important in high-performance applications and can significantly improve the dynamic response and stability of the motor.
The starting torque performance of the inverter is also excellent. In open-loop vector control mode, the starting torque can reach 150% of the rated value at 0.25Hz, and in closed-loop vector control mode, the starting torque can even reach 180% of the rated value at 0Hz. This feature enables the inverter to overcome the large static friction at startup, ensuring that the motor can start smoothly, and is suitable for applications under various load conditions.
