2 Pcs 816 8x16mm 0816 Coreless Motor D...

The 816 Coreless Motor (8mm x 16mm) is the high-performance muscle behind micro-aviation. At Electrapac, we recommend this pair of "Hollow Cup" motors for builders looking to upgrade their 1S micro FPV quads, tiny whoops, or DIY indoor flyers that require a massive thrust-to-weight ratio.Product OverviewThese coreless motors are engineered for extreme RPM and rapid acceleration. Unlike standard DC motors, the "Coreless" design removes the heavy iron core from the rotor, allowing the motor to reach speeds of up to 55,000RPM almost instantaneously. This makes them perfect for the split-second maneuvers required in FPV drone racing.Key Features for Electrapac CustomersIncredible Power Density: Despite weighing only 4.5g, these motors deliver the high torque needed to carry micro FPV cameras and VTX modules.Strong Neodymium Magnets: Built with high-grade NIB magnets to maintain high RPM even as the battery voltage drops during flight.Plug-and-Play Compatibility: Standard 8mm diameter fits most 75mm to 85mm micro drone frames and "Tiny Whoop" style mounts.Low Vibration: The precision-balanced hollow cup design reduces airframe resonance, resulting in smoother video feeds and better flight controller performance.Propeller Included: Each pair comes matched with high-efficiency propellers, optimized for the 1.0mm shaft to ensure a tight, no-slip fit.Technical Implementation GuideTo get the longest life out of your Electrapac micro motors, follow these best practices:Clockwise (CW) vs. Counter-Clockwise (CCW): * Red/Blue wires: Usually indicates a CW motor.Black/White wires: Usually indicates a CCW motor.Always check the rotation before finalizing your soldering to ensure your drone doesn't flip on takeoff.Break-in Period: For maximum longevity, run the motors at 50% throttle for the first 2-3 minutes of their life without propellers to let the brushes seat properly.Cooling: Because these are high-RPM motors, they generate heat. Ensure your frame allows for some airflow around the motor can to prevent the internal brushes from melting.Primary ApplicationsMicro FPV Quads: The standard motor for 75mm-85mm indoor racing drones.DIY Micro Planes: Creating lightweight "park flyers" and ultra-light foamies.Science Projects: Building high-speed centrifugal fans or miniature vibration haptics.Small Scale Robotics: Providing high-speed drive for tiny, lightweight mobile robots.Why Shop at Electrapac?We curate our 816 Coreless Motors to ensure they meet the 55,000RPM threshold, giving you the "punch" you need for indoor acro-flying.
