Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

Recent patent disclosures indicate that BYD has strengthened its work on variable-flux permanent-magnet synchronous ...

Two great minds in permanent-magnet-free motor design are fusing their know-how to create an even more capable inductive electric motor. Mahle and Valeo have teamed up to introduce what they call the ...

The race is on to create an ebike motor that adds the least amount of weight and bulk as physically possible, disappearing away into the bike where it's barely seen or heard but is felt on every pedal ...

Compromise is key to keeping a team humming along. Say one person wants an inrunner electric motor, and the other prefers ...

Never mind present-day’s bonny blather on the benefits of electric, hydrogen and biofuel power. How do you feel about magnets? Better make up your mind, stat; as of this morning, a company named ...

How the switched reluctance motor's (SRM) architecture eliminates the need for magnets and rotor windings. Why SRMs are some of the most rugged and cost-effective motor technologies available. A look ...

Dynamic shaft seals often fail in submersible systems, but the SplashValve eliminates seals entirely—using magnetic coupling ...

This study focuses on the direct-drive ultrasonic resonant motors called PILine ® motors. Their direct-drive design enables ultra-low response times and highly precise positioning without any backlash ...

The trend in the automotive industry is to replace mechanically actuated systems with systems based on electric motor technology. The traditional brushed dc motor is not suitable for many of these ...
