Abstract: This paper presents a simplified modelling, analysis and simulation of permanent magnet brushless DC (PMBLDC) motors for sensorless operation. This model provides a mechanism for monitoring and controlling of voltage, current, speed and torque. The sensorless scheme employs direct back emf-based zero crossing detection for controlling the dynamic characteristics.

Keywords: PMBLDC motors; modelling; sensorless operations; back emf zero cross point; simulation; permanent magnet brushless DC motors; voltage control; current control; speed control; torque control; monitoring.
