Force and Velocity Ripple Reduction of the New Linear Motor
IEEE Access, 2021 This study presents a new linear motor with an E-core stator and a homopolar permanent magnet (PM) mover. The velocity and force ripples of the motor are effectively reduced by an optimized structure and effective force compensation.

An Observer-based design for cogging forces cancellation in permanent magnet linear motors [PDF]
Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009 This paper adresses the high precision positioning issue of permanent magnet (PM) linear motors, in presence of spatially periodic forces, also known as cogging. Using an internal model representation of this perturbation, an observerbased controller only relying on position measurements is derived.
