BLDC Motor Speed Control Using Co-Simulation Of Multisim and Labview

Abstract: Brushless dc motor is finding various applications in the present day scenario. They have improved efficiency, higher speed, better torque speed characteristics and faster dynamic response when compared with the traditional motors. In this paper, a controller is developed based on co-simulation of multi sim and lab view and is presented for low cost brushless dc motor drive with low-resolution hall sensors. The driver circuit is made using a low cost MOSFET gate driver IC in multi sim and the controller is developed in lab view. A hall sensor is usually used to commutate the BLDC motor and the hall sensor output is used as the gate pulse for the six pulse inverter. The effectiveness of the design was verified through co-simulation. Keywords: BLDC, gate driver circuit, control circuit multi sim, lab view, co-simulation.
