| Abstract |
This paper presents particular methods for
deployment of the sensorless Permanent Magnet Brushless DC
(PM BLDC) motor drive system. The waveform of the motor
internal voltages (or back emf) contains fundamental and higher
order frequency harmonics. Therefore the third harmonic
component is extracted from the stator phase voltage. The
resulting third harmonic signal maintains a constant phase
relationship with the rotor flux at any motor speed and load
condition. In addition, in this paper, a simple starting method and
speed estimation approach are also proposed. Experimental
results are provided, to demonstrate the validity of the proposed
control method. |
