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 ...

A straight line may not be the best path between two or more rotors. • Electric machines with noncoaxial rotors date back to the 19th century, but today’s electronic controls now make them practical. ...

Historically, generator inspections require rotor removal (Figure 1). There’s a significant level of risk during this process due to possible generator damage during the disassembly, and it also ...

Serious engineering work on contra-rotating open rotors for aircraft propulsion dates back to the late 1940s, particularly as a means to enhance fuel efficiency and extend the endurance of long-range ...
