Product Description

External rotor DC brushless motor, innovative design, with significant advantages. Its rotor is on the outside and the stator on the inside, featuring a unique structure. By adopting electronic commutation technology and eliminating mechanical commutators, mechanical wear and sparks are eliminated, significantly reducing maintenance and lowering the failure rate. During operation, as there is no interference from mechanical commutators, it runs more smoothly with extremely low noise. Moreover, the rotor is composed of permanent magnets and bearings, without energy-consuming components such as resistors and brushes. It has a high efficiency in electrical energy conversion and outstanding energy-saving effects. In addition, the brushless design makes its lifespan much longer than that of traditional motors. In fields such as industrial automation, smart home, and medical equipment, it can operate stably and reliably with outstanding performance, providing strong power.
