Fluid Analysis of Hollow Shafted BLDC Motor for Fan Blower Application

In recent years, BLDC motors have been used in various fields, because they are more reliable and efficient than conventional DC motors. In this paper, the hollow shaft BLDC motor is proposed for increasing the flow efficiency of the fluid for a fan blower. As the result of fluid analysis with the BLDC motor for fan blower, the energy efficiency of fluid transfer with the hollow shaft BLDC motor was increased compared with the conventional shaft BLDC motor.
