Shaft Mechanical Design of 250 kW Electric Motor

One part of the complexity in designing electric motors is to provide suitable mechanical support of the motors. BPPT is developing a 250 kW electric motor to be applied on 100 Teus container vessels. Minimum information available is used to design it from the scratch. To fulfil the design objective, that includes manufacturability with high local contents, the optimal design of shaft and the choice of suitable bearings are crucial. This paper provides the contribution of the shaft design and bearing calculation in the overall design of the motor. As supplication to the study, a numerical simulation based on Finite Element Analysis is also carried out.
