INVT GD20-09 series: Performance advantages of low-frequency heavy-duty lifting machinery
Low frequency high torque output capability
The full name of GD20-09 is Goodrive20-09 crane specific frequency converter, which is a product created by INVT for the low-frequency heavy load characteristics of lifting machinery. Its dedicated vector algorithm can output sufficient rated torque around 0Hz, meeting the core requirements for heavy-duty starting of lifting equipment. Compared to general frequency converters, this product has no shaking or slipping during the start-up phase, and has better torque stability during low-speed operation.
Speed stability under heavy load
The Goodrive20-09 crane specific frequency converter has extremely strong speed anti-interference ability. When the lifting load suddenly increases or decreases, it can quickly adjust the output state and maintain stable speed. During the dynamic process of lifting machinery, there will be no significant drop in rotational speed, ensuring the smoothness of heavy lifting and avoiding damage to the mechanical structure caused by impact.
Long term overload operation capability
The INVT GD20-09 series supports short-term overload operation and can cope with instantaneous overload and impact load scenarios of lifting machinery. The product has a reasonable overload protection curve, which not only retains sufficient overload margin to cope with sudden working conditions, but also effectively protects the motor and frequency converter body, and adapts to complex load fluctuations in lifting operations.
Low speed precise positioning performance
The GD20-09 crane specific frequency converter has excellent low-speed control accuracy and can achieve smooth operation at extremely low speeds, meeting the precise positioning requirements of lifting machinery. In scenarios such as heavy object placement and mold lifting that require low-speed fine-tuning, the product can output stable low-speed torque, accurately position without crawling, and improve the precision and operational experience of lifting operations.
