Product Description

Outer rotor motor-W4215


The outer rotor motor is an efficient and reliable electric motor widely used in industrial production and household appliances. Its core principle is to place the rotor outside the motor. It uses an advanced outer rotor design to make the motor more stable and efficient during operation. The outer rotor motor has a compact structure and high power density, allowing it to provide greater power output in a limited space. In applications such as drones and robots, the outer rotor motor has the advantages of high power density, high torque and high efficiency, so the aircraft can continue to fly for a long time, and the performance of the robot has also been improved.




Production introduction


The outer rotor motor has higher efficiency than the traditional motor, can more effectively convert electrical energy into mechanical energy, and reach a 90% conversion rate, its high torque is also larger than the traditional motor, can achieve fast start and reach the rated speed which meet the high requirements of the body parts of industrial robots and is very suitable for high load continuous operation applications. In addition, the outer rotor motor has no brush, which reduces the possibility of failure during operation, and the low noise can also be better applied to noise sensitive occasions. In addition, given the flexible design of the outer rotor motor, it can be compatible with various machine finger structures and control systems, providing users with more convenience and choice. Outer rotor motors play an important role in both automated production equipment and robotic research and development.
