Incremental encoder based BLDC drives are widely employed in industry whenever smooth and efficient operation is needed in the whole speed range. Their weak spot lies in the need for a phase of initial alignment, traditionally performed by forcing the motor through a series of fixed phase supply configurations in an open loop stepping mode. This strategy of alignment causes ample mechanical vibrations which can be intolerable for certain applications. This paper presents a novel algorithm for determining the initial rotor sector and aligning the encoder with the motor while minimizing vibrations and oscillations. © 2012 Elsevier B.V.

Abstract

Incremental encoder based BLDC drives are widely employed in industry whenever smooth and efficient operation is needed in the whole speed range. Their weak spot lies in the need for a phase of initial alignment, traditionally performed by forcing the motor through a series of fixed phase supply configurations in an open loop stepping mode. This strategy of alignment causes ample mechanical vibrations which can be intolerable for certain applications. This paper presents a novel algorithm for determining the initial rotor sector and aligning the encoder with the motor while minimizing vibrations and oscillations. © 2012 Elsevier B.V.
