IPET SYSTEM's I8 is an integrated propulsion solution for multirotor drones, featuring a motor with an ESC (electronic speed controller) embedded directly inside the housing for enhanced space and weight savings and reduced wiring. The I8 is designed for quadcopters with takeoff weights of 16 to 18 kg, and hexacopters with takeoff weights of 24 to 27 kg.
The I8 delivers 12.1 g/W overall efficiency at 4.0 kg thrust and up to 11 kg maximum thrust, and has supported more than 100 minutes of verified flight time on an endurance-focused multirotor platform. The integrated design is manufactured with high-quality machining and precision assembly, ensuring high reliability and a service life designed for 10,000 hours of operation.
The embedded ESC includes a health monitoring module that tracks real-time operating conditions, with overcurrent, over-temperature, overvoltage, stall and throttle-signal-loss protection for dependable mission performance.
