This paper presents the implementation of a three-leg voltage source inverter fed by a brushless DC motor. The open-loop speed control with direct torque is employed in this motor. The rotation of the motor is controlled by using an optimal voltage vector which is related to the calculation of stator flux and electromechanical torque. The experimental results show that this system has greater capability to reduce spike and ripple on the voltage, current, stator flux, and electromechanical torque than the conventional speed controller which feeds the voltage vector from the hall-effect sensors.
