N2 - This paper mainly studies the variation rules and optimizations of rotor pole shoe deformations in the interior permanent magnet synchronous motor. With two types of the V-shaped rotor structures taken into account in the study, the effects of the geometrical parameters such as the thickness of magnetic bridge, the thickness of magnetic rib, and the V-shaped angle are analyzed by the finite element method. Combined with the advantages of V-shaped type and spoke type rotor, this research proposes a novel interior rotor structure, which adopts the modular rotor core and the tangential magnetized PMs with the trapezoid shape. The simulation results prove that the proposed rotor structure can effectively reduce the rotor deformation without increasing the magnetic flux leakage, which ensures the electromagnetic and mechanical performances of the motor.
