4PCS Coreless Micro Motor (8.5x20mm, 3.7V, 46000rpm)

This set of four coreless micro motors is engineered for lightweight, high-speed applications such as DIY quadcopters, miniature robots, and motion prototypes. Running on a standard 3.7V supply, each motor delivers an impressive 46000rpm output in a compact form factor. They are ideal for makers, students, and hobbyists building miniature drive systems.

High-speed 46000rpm performance

Each coreless micro motor delivers a high-speed output of 46000rpm at its rated 3.7V operation. This rapid rotational speed makes them well suited for miniature aerial propulsion and high-velocity mechanisms.

Compact 8.5x20mm form factor

Featuring compact dimensions of 8.5mm in diameter and 20mm in length, these motors fit neatly into tight chassis and lightweight airframes. Their small profile helps reduce overall project mass without sacrificing speed.

Standard 3.7V voltage rating

Rated for 3.7V operation, these micro motors integrate seamlessly with single-cell LiPo battery setups and common microcontroller motor drivers. This standard rating simplifies power system design in portable builds.

Versatile motion prototype applications

Supplied as a 4-piece pack, these motors provide direct drive power for micro quadcopters, miniature robotics, and custom kinetic prototypes. They offer a straightforward solution for multi-rotor configurations or small-scale actuation.
