A novel speed and position estimation of the brushless DC motor at low speed

Abstract

A novel estimation technique for speed and position of BLDC motor is proposed. The new estimation method use trapezoidal waveform of back-EMF with speed information. To estimate the trapezoidal waveform of back-EMF, three phase currents information and DC line voltage information of inverter and terminal voltage are used. The proposed new estimation method… (More)
