Abstract

This paper presents the speed torque characteristics of BLDC motor on load in forward and reverse direction. The Hall sensors of the BLDC motor is bestowed as the input to the ARM controller. The PWMs are produced depending upon the input of the controller. In order to convert DC to three phase AC, three phase bridge inverter with MOSFET as switches is used. The generated PWMs are inputted to the gate of the MOSFETs in the inverter. The output of the inverter is the energization sequence of BLDC motor and only two phases energizes at once. Dynamometer is used for encumbering the motor. The results are acquired for variable load torque and Speed torque characteristics are observed.
