Dualsky XM4255EA V3 Brushless Outrunner Motors – EA Series High-Efficiency Electric Drive

The Dualsky XM4255EA V3 Brushless Outrunner Motor Series is a high-efficiency electric drive platform engineered for applications requiring controlled torque delivery, stable RPM characteristics, and dependable thermal performance. Built on Dualsky’s refined EA-series architecture, the XM4255EA V3 motors combine optimised electromagnetic design with robust mechanical construction to deliver smooth, predictable power output under sustained load.

This motor platform is widely used in RC aircraft, UAV propulsion systems, and electric drive platforms, where efficiency, reliability, and repeatability are essential. The availability of multiple KV options within the same mechanical footprint allows precise matching to voltage, propeller, and system requirements without redesigning the installation.

Beyond RC applications, the XM4255EA V3 series is well suited to robotics systems, engineering projects, academic research, laboratory test rigs, experimental machinery, defence-related prototyping, and invention-driven R&D environments, where brushless outrunner motors are integrated into custom electric drive systems. Its balanced design and consistent operating behaviour make it suitable for both developmental testing and operational deployment.

All motors supplied are genuine Dualsky products and are supported with manufacturer backing, technical guidance, and after-sales support, making this series appropriate for individual builders, institutions, universities, research laboratories, and bulk procurement.
