Abstract
This Paper propose a novel sensorless drive system for the trapezoidal brushless DC motor in Bow speed region. The inverter DC input voltage is controlled by step-down converter for low speed operation. A indirect rotor position sensing technique based on a detailed analysis of the terminal voltage characterisrics is proposed in this paper. A sensorless drive system is implemented using a TMS320F240 for the main process and IPM(Intelligent Power Module) for the inverter.
