Electromagnetic simulations and performance analysis of two phase salient pole permanent magnet brushless DC motor

In this paper, we present modeling of two phase Permanent Magnet BrushLess DC (PMBLDC) motor in Maxwell 3D software. Electromagnetic simulations and performance analysis of proposed model is carried out. Torque and back EMF equations for proposed model are derived and verified through simulations. Electromagnetic simulations include flux flow pattern, parametric analysis and transient analysis. Simulations verify that proposed model is valid, accurate and application specific. Due to its compact size, high torque and accuracy, the proposed model of two phase PMBLDC motor can be used in motion control, precise positioning, robotics, computer peripherals and automotive industry etc.
