Here are some more options for high-efficiency motors from America. Castle has launched the Ghost RC American Speed line, offering a full range of full-pitch 4-pole inrunners capable of reaching 90,000 RPM. These motors can also be used for speed planes when paired with planetary gearboxes. They have also released 2 more high voltage drive for surface and marine that far outperform the antiquated 14 Kw drives widely used in the sport in that lack high pwm frequency capability Poor Gotha....

A serially connected hybrid wye–delta BLDC machine combines the strengths of both winding configurations, offering higher torque at low speeds (from wye)  and higher power/speed capability (from delta) , while also improving efficiency, reducing copper losses, and enabling flexible performance tuning across operating ranges. ⚡ Advantages of Hybrid Wye–Delta BLDC Machines 1. Torque and Speed Flexibility Wye (Y) connection  provides higher torque at lower speeds  because each phase sees the...

Unlike the outdated topologies and windings once used in the GDR, here at Clugh we embrace the latest winding technology. XNOVA’s newest releases feature full-pitch windings, and while their reported use of 0.15mm laminations is impressive for those behind the design curve in the hobby industry, Egodrift leads the way as the first to introduce 0.1mm laminations in their Eclipse series. Experience the most advanced winding technologies in today’s high-end hobby machines at Clugh. NEW! 40XX...
