March 29, 2023 by Mark Allinson Leave a Comment

Flat BLDC outrunner motor is a high-efficiency, high-power-density motor, which is widely used in robotics, power tools, medical equipment, and other fields due to its compact shape, light weight. DONCEN MOTOR explains in this article.

Robotics engineers are more inclined to use small size and high power external rotor brushless motors to replace conventional drive motors in their applications.

Basic research stage (mid-1980s to mid-1990s): At this stage, motor technology began to develop in the direction of flat brushless external rotor motors.

The researchers mainly focus on the structure, materials and manufacturing process of the motor. At this time, the motor has begun to be used in some high-performance electric tools, medical equipment and other fields.

Technological innovation stage (from the mid-1990s to the beginning of the 21st century): In this stage, major breakthroughs have been made in motor technology, and the application of flat brushless external rotor motors has been further promoted.

The weight, volume, power density and other indicators of the motor have been significantly improved, and the application fields of the motor have been further expanded.

Mature application stage (from the 21st century to the present): At this stage, flat brushless external rotor motors have become one of the important branches of motor technology and have been widely used.

The performance, reliability and service life of the motor have also been further improved, enabling it to be used in more fields, such as electric vehicles, smart homes, drones, robots, and so on. At the same time, significant progress has been made in the development of green, intelligent and integrated motors.

With the increase of application requirements, the motor speed requirements are also getting higher and higher.

Currently, the external rotor brushless motors on the market are usually low KV and high torque. Therefore, the high KV external rotor brushless motors in the future Electric motors will occupy a part of the market.

The service life and performance of the motor in high temperature environment are limited, so the future flat brushless external rotor motor will improve its high temperature resistance through the improvement of materials and structure.

The future flat brushless external rotor motor will be more integrated. By using new manufacturing technology and materials, sensors, drivers and control circuits are integrated into the motor, thereby reducing the volume and weight of the system.

The future flat brushless external rotor motor will be more intelligent. Through built-in sensors and control circuits, adaptive control and intelligent monitoring can be realized to improve the efficiency and performance of the motor.

The future flat brushless external rotor motor will pay more attention to environmental protection and sustainable development, and reduce environmental pollution and resource consumption by using environmentally friendly materials and energy-saving technologies.

The flat design of the outer rotor brushless motors is particularly suitable for robot joint motors. High power output in a small size is a characteristic favored by robotics engineers.

The precise control and high torque characteristics of the outer rotor motor can be adapted to the robot drive wheel motor

Outer rotor brushless motors have a good application in power tools.
