Abstract

Aiming at the problem that the asynchronous motor used in the submersible LNG pump has reduced locked torque and long starting time at low temperature, the causes of this problem are analyzed theoretically. A scheme of using brass instead of cast aluminum cage rotor winding and reducing the cross-sectional area of cast aluminum rotor winding is proposed, and the two schemes are compared. The corresponding simulation calculation was carried out using Ansys Maxwell, and the dynamic process of motor starting and the rotor winding loss during stable operation were obtained. Theoretical analysis and simulation results show that the improved scheme is simple, practical and effective.
