Linear induction motors (LIMs) are specialised electromagnetic machines that convert electrical energy directly into linear force, thereby eliminating the intermediary rotary step inherent in ...

The first linear motor was conceived by Wheatstone more than 100 years ago. But large air gaps and low efficiencies prevented linear motors from being widely used. Though they still have relatively ...

Here’s how power losses and inertia matching affect the efficiency of linear drives. The operating efficiency of linear drives is of growing concern to machine designers. Here's a look at three common ...

Machine and robot builders recognize linear motor benefits, but some are reluctant to integrate the components into design because of incomplete understanding of the technology. Here we overcome that ...

This study provides a comprehensive overview of the ALMs for direct-drive applications, mainly focusing on their topology structures, working principles, performances evaluation and control techniques ...
