8520 Mini DC Coreless Motor 3.7V Speed Rotation for Drone Quadcopter Replacement

8520 Mini DC Coreless Motor 3.7V Speed Rotation for Drone Quadcopter Replacement Description

Compact 3.7V micro DC motor designed for precise, speed smallscale applications. Key benefits rotational speed: about 41000 rpm without load to improve conversion rates, enabling fast response for miniature mechanisms. Low power draw: current about 150 mA at 3.7V minimizes power consumption for batterypowered projects. Compact shaft: 1 mm diameter and 5.5 mm length for easy coupling with small gears, pulleys, or adapters. Ready to install: 80 mm cable length provides convenient reach for wiring and placement in constrained layouts. Predictable sizing and performance that simplify integration into custom assemblies and repairs. How this product solves common problems Fits tight spaces where larger motors will not, allowing designers to reduce overall device size without losing speed. Low current requirement helps extend runtime in portable and batteryoperated systems. Standard shaft dimensions make it straightforward to attach common micromechanical interfaces, avoiding custom machining. Adequate cable length reduces the need for additional wiring or extensions during assembly. Specifications Voltage: 3.7V Current: about 150 mA Noload speed: about 41000 rpm to improve conversion rates Shaft diameter: 1 mm Shaft length: 5.5 mm Cable length: 80 mm Typical applications Hobby and educational robotics: drive small wheels, microactuators, or sensor positioning mechanisms. Miniature cooling or airflow devices: power small fans or impellers in tight enclosures. Precision hobby projects and model making: turn lightweight gears, pumps, or rotary components where space and power are limited. Notes for use Noload speed is specified; actual speed under load will vary with torque and system resistance. Verify shaft coupling and mounting arrangements match the 1 mm diameter and 5.5 mm length before final assembly. This motor is intended for integration into small electromechanical systems that require compact size, rotational speed, and modest current consumption.
