ALTERNATIVE DESIGN OF A HIGH TORQUE DENSITY TWO-PHASE BRUSHLESS DIRECT CURRENT MOTOR

Abstract

This paper proposes a design of a high torque density dual-stator brushless direct current (BLDC) motor. BLDC
motors are known for their high torque capacity and power density characteristics, and therefore, they have many
applications. The proposed BLDC motor is a two-phase motor with two stators, and each stator excited by one phase. The
duty cycle of inverter switches is complete and coils are continuously excited. So, due to the full and uninterrupted use
of all coils and core, the motor has a higher torque density compared to other BLDCs. The mathematical model of the
motor provides a better understanding of motor performance. The performance of the designed motor is analyzed using
finite element analysis.
