Split-Type Permanent Magnet Shaft Generator

Split-Type Permanent Magnet Shaft Generator

The split-type permanent magnet shaft generator is a dedicated customized model for large vessels and offshore platforms, adopting a split-type assembled structure. It can be installed and serviced without disassembling the vessel’s main shaft, perfectly solving the equipment disassembly challenge for large vessels. With high power, high adaptability, and easy maintenance, it is the core energy-saving power supply device for large heavy-load marine equipment.
