The energy consumption required for ship operation is large. Based on the concept of energy saving and consumption reduction, it is necessary to conduct research on the energy-saving technology of its electric motors on the existing basis, do a good job in the operation method and operation parameter control, and reduce the operating efficiency of the ship without affecting the operating efficiency. energy consumption. The energy-saving design of the motor can generally be carried out from three aspects, namely, improving the efficiency of the motor, applying the appropriate operation plan chart and the optimal shaft output power, etc. In the actual design, the optimization scheme should be determined based on the operating characteristics of the marine motor to achieve energy saving. Purpose.
