Comparing the force ripple during asynchronous and conventional stimulation [PDF]
Muscle and Nerve, 2014 ABSTRACTIntroduction: Asynchronous stimulation has been shown to reduce fatigue during electrical stimulation; however, it may also exhibit a force ripple. We quantified the ripple during asynchronous and conventional single‐channel transcutaneous stimulation across a range of stimulation frequencies.

Force and Velocity Ripple Reduction of the New Linear Motor [PDF]
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. Firstly, the mechanical structure, magnetic paths and operation principles are introduced. Force analysis is carried out
