The 630kw Three Phase Asynchronous Motor adopts IP55 protection level, which can effectively prevent dust and water spray from entering, suitable for damp and dusty sand dredging ship environment,
1. Its squirrel cage rotor structure is simple and reliable, requiring no slip ring or electric brush maintenance, and has a low failure rate
2. Fully enclosed self fan cooling (IC411) design achieves forced ventilation through internal fans, with high heat dissipation efficiency, and can meet the requirements of continuous heavy-duty operation

The 630kW three phase asynchronous motor adopts a copper bar rotor design, which has the following advantages compared to copper wire winding rotors:
1. Copper bars have a larger cross-section and stronger current carrying capacity
2. Can withstand higher temperature rise and transient overload
3. Especially suitable for harsh environments and heavy load conditions
4. Avoid accidental shutdown caused by motor overheating or overload
5. Ensure the continuous and stable operation of the production line
This 630kW three phase asynchronous motor is particularly suitable for applications such as sand dredgers in the Democratic Republic of Congo that require high reliability of motors
