ePropelled, a provider of intelligent propulsion systems, announced the expansion of its Sparrow line of high-efficiency brushless motors with three new models engineered for mission-critical defense applications.As modern warfare relies increasingly on uncrewed systems, propulsion technology has become a key enabler of endurance, stealth and payload flexibility. The APM 1404, APM 2207.5 and APM 3115 add new levels of power density, reliability and environmental robustness to the Sparrow family, enabling defense customers to build more capable unmanned aerial systems.The demand for lightweight, efficient propulsion for defense platforms—particularly small UAVs, loitering munitions, ISR platforms and autonomous systems—has accelerated the need for compact, rugged motors capable of consistent performance in harsh conditions.The expanded Sparrow line addresses this demand with propulsion systems that combine high efficiency, low weight and resilience. Key advantages include improved mission endurance, optimized power-to-weight ratios for small and mid-sized platforms, ruggedized construction, low acoustic signatures for stealth operations and reliability suited to mission-critical deployments.Introducing the new Sparrow models:APM 1404 – Ultra-Light Micro Propulsion Designed for extremely compact platforms, the APM 1404 provides high thrust and efficiency at minimal weight, supporting micro-UAVs and short-range ISR drones that require maximum efficiency in a small form factor.APM 2207.5 – High-Output Mini-Class Performance Offering a balance of power and compact design, the APM 2207.5 delivers enhanced torque and thermal performance, making it well suited for small tactical UAVs, vertical-lift microsystems and electric tactical subsystems.APM 3115 – High-Power Tactical-Grade Motor Engineered for demanding mission profiles, the APM 3115 provides high propulsion output for loitering munitions, medium-range ISR drones and hybrid tactical platforms.“As defense requirements evolve, propulsion technology must evolve with them,” said Nick Grewal, CEO of ePropelled. “By expanding our Sparrow line, we’re providing system integrators and defense innovators with motors and propulsion systems that are smaller, more efficient, more powerful and more reliable than ever before.”ePropelled continues to work with defense organizations worldwide to deliver propulsion and power systems that increase the capabilities of next-generation unmanned and autonomous platforms.Availability: The APM 1404, APM 2207.5 and APM 3115 models are available at epropelled.com, where full technical specifications and performance data are posted.
