Presently, the automotive industry is being renovated with the help of an electrical machine, batteries, and power electronic components. In this technological shift, permanent magnet machines (PMSM) are mainly preferred for traction, because of their high efficiency and power density. The noise, vibration, and harshness (NVH) performance of the electrical machine is one of the main challenges, due to the tangential and radial electromagnetic forces. In this research study, a geometrical and electrical approach has been executed to reduce the radial force, which has a larger impact on vibration and noise. Initially, a permanent magnet synchronous motor with a V-shaped magnet configuration has been designed and the output performances are analyzed. The base structure (V-shaped magnet without duct) highlights that the radial force in the 12/3 and 12/12 order is higher, which will increase the vibration and noise of the motor. In this proposed geometrical approach, a duct has been introduced in the rotor outer periphery, which will reduce the airgap permeance and minimize the radial force. Different duct-shaped rotor configuration has been simulated using finite element analysis. The effectiveness of different duct shapes (like circle, rectangle, and ellipse) is analyzed and compared. The radial electromagnetic forces of a motor without duct and with duct have been provided. After placing the duct, the radial force was reduced which minimizes the vibration and noise. The ellipse duct rotor configuration shows better electromagnetic performance compared with rectangle and circle-shaped ducts. An electrical approach has been proposed to minimize the radial electromagnetic forces by injecting harmonic current and current angle on d-axis and q-axis. Finite element analysis with various results ensures the improved structure with an ellipse-shaped duct can reduce the radial force of the motor by around 36%.
