Outrunner BLDC Motor

DONCEN Motor specialize in the development, design, and production of high-performance outrunner BLDC motors that boast exceptional capabilities. Our MX series of outrunners is available in power ranges spanning up to 1000W.

Initially designed for the Robot industry, our outrunners were created to fulfill a need for powerful yet lightweight motors with high torque. As time has passed, we have refined our outrunner design to make it suitable for a variety of applications, including those in the commercial and AGV power system as well as in other industrial settings.

Our outrunners are highly compact in design and possess leading power-to-weight/Volume ratios.

All of our outrunner motors are customized and can be tailored to meet the specific requirements of our clients. Customizations can include adjustments to the housing, shaft, winding, number of poles, magnet material, potting material, cooling, and even the addition of a gearbox, among other things. By incorporating these adjustments, we are able to create the most efficient, lightweight, robust, and powerful motors to suit our clients’ specific needs. Our motors are perfect for applications with space, weight, and energy supply constraints.

What is a Outrunner Brushless Motor? ( Knowledge Share)

Outrunner brushless motor is a type of brushless DC electric motor. T stator is mounted on the outside of the rotor. This configuration allows for a more efficient use of space, and results in a higher power-to-weight ratio than other brushless motor designs. Compare with the inrunner bldc motors, outrunner bldc motors are lighter in weight, higher in power and huger in torque. Outrunner brushless motors are typically used in applications where high power and/or speed are required.
