Outrunner Brushless DC Motor – Brushless DC Motor Solutions for Electric Skateboard and Esurfing/Efoil/Ejet Parts

An outrunner brushless DC motor is a type of brushless motor with an external rotor design that delivers high torque density, efficient heat dissipation, and compact form factors.                                                                                          Outrunner motors are ideal for applications requiring robust torque output, low-speed operation, and high reliability under load.                                                                                                                                                                                  They are widely used in Electric Skateboard, Esurfing/Efoil/Ejet Parts, Boat Engine Thruster, industrial fans, and precision automation equipment, especially where high power density and thermal management are essential.

Outrunner brushless DC motor Product Overview

An Outrunner Brushless DC Motor (BLDC) is designed with its permanent magnets mounted on the outer rotating shell and the stator windings fixed at the inner core.

In this design, the rotor housing directly carries the magnets and delivers torque, which delivers significantly higher torque density and improves heat dissipation.

This structural innovation enables outrunner BLDC motors to achieve:

Substantially higher continuous torque output

Superior thermal performance with low thermal resistance

High power density and compact axial length

Smooth low-speed operation and suitability for direct-drive applications

These advantages make them the ideal choice for applications demanding high torque density, robust thermal management, and reliable performance in compact systems, such as in robotics, drones, and precision automation.

Outrunner Brushless DC Motor by Frame Size

We classify our cor Outrunner Brushless DC Motor primarily by frame size, which is the most common and efficient way for engineers to narrow down motor selection.Each frame size category includes multiple series and sub-models with different power ratings and winding options.
