Automatic Advance Angle Control Algorithm using Anti-Windup Output Voltage and Voltage Equation for Expanding High-Speed Operation Region of 7-Phase BLDC Motor

This paper proposes an automatic advanced angle algorithm for the high-speed operation region control of 7-phase BLDC motor. when the 7-phase BLDC motor is operated at high speed, phase current delay occurs with respect to the phase of the back-emf due to the increase of the reactance component of the phase winding, so that the torque ripple and the speed control performance are greatly deteriorated. This paper can calculate the effective...
