INVT GD350-037G-4-CCS ship specific frequency converter

Performance analysis of INVT GD350-CCS series ship frequency converter with excellent all wheel drive and all-around control

1. Multi type motor compatible drive
The GD350-CCS series ship specific frequency converter supports asynchronous motor and permanent magnet synchronous motor drive, covering multiple types of motors such as variable frequency motors, ordinary asynchronous motors, asynchronous servo motors, synchronous motors, direct drive motors, and electric spindles. It integrates multiple motor drive capabilities and is suitable for the needs of marine diversity equipment.

2. Multi mode control with precise output
The product supports three modes: space voltage vector control, PG free vector control, and PG vector control, which can meet the control requirements of torque, speed, and position. The asynchronous machine has a PG free speed ratio of 1:200 and a PG speed ratio of 1:1000, with a maximum speed control accuracy of ± 0.02%.

3. Low frequency high torque starting performance
The GD350-CCS series ship specific frequency converter is equipped with a unique I/F control and has constant current source characteristics. The asynchronous machine can output 150% of the rated torque at 0.25Hz, the synchronous machine can output 150% of the rated torque at 2.5Hz, and can reach 200% of the rated torque at 0Hz in PG vector mode, suitable for heavy-duty starting scenarios.

4. Smooth speed tracking before restarting
The product has a speed tracking restart function, which can achieve smooth start without impact for rotating motors. It has low current impact and high operational stability. After a 50Hz emergency stop, there is no obvious jerking when running again, effectively avoiding mechanical impact caused by sudden stop and restart of the equipment and extending its service life.
