What is Coreless Motor
Hollow cup motor belongs to DC permanent magnet servo and control motor, which can also be classified as micro special motor. Hollow cup motor has outstanding energy-saving characteristics, sensitive and convenient control characteristics and stable operation characteristics, and its technology progressiveness is very obvious. As a high-efficiency energy conversion device, it represents the development direction of motor in many fields. The structure of hollow cup motor breaks through the rotor structure of traditional motor, and adopts coreless rotor, also known as hollow cup rotor. This novel rotor structure completely eliminates the power loss caused by the eddy current formed by the iron core.
At the same time, its weight and moment of inertia are greatly reduced, so as to reduce the mechanical energy loss of the rotor itself. Due to the structural change of the rotor, the operating characteristics of the motor have been greatly improved. It not only has outstanding energy-saving characteristics, but also has the control and driving characteristics that can not be achieved by the iron core motor

Classification & characteristics of Coreless Motor
The hollow cup motor is divided into two types: brush and brushless. The rotor of the brush hollow cup motor has no iron core, and the stator of the brushless hollow cup motor has no iron core. The winding adopts triangular connection method
Hollow cup motor mainly has the following characteristics:
- Energy saving characteristics: the energy conversion efficiency is very high, and its maximum efficiency is generally more than 70%, and some products can reach more than 90% (iron core motor is generally 70%).
- Control characteristics: start and brake quickly, respond very quickly, the mechanical time constant is less than 28 milliseconds, and some products can reach less than 10 milliseconds (generally more than 100 milliseconds for iron core motors); In the high-speed operation state in the recommended operation area, the speed can be adjusted sensitively and conveniently.
- Drag characteristics: the operation stability is very reliable and the speed fluctuation is very small. As a micro motor, its speed fluctuation can be easily controlled within 2%.
In addition, the energy density of the hollow cup motor is greatly improved, and its weight and volume are reduced by 1 / 3-1 / 2 compared with the iron core motor with the same power
Application of Coreless Motor
Because the hollow cup motor overcomes the insurmountable technical obstacles of the iron core motor, and its prominent characteristics focus on the main performance of the motor, it has a broad application field. Especially with the rapid development of industrial technology, higher expectations and requirements are constantly put forward for the servo characteristics of the motor, so that the hollow cup motor has an irreplaceable position in many applications.
After the application of hollow cup motor has entered the large industrial and civil fields from the military and high-tech fields, it has developed rapidly in the past ten years, especially in the industrial developed countries, which has involved most industries and many products.
- Servo system requiring fast response. Such as rapid adjustment of missile flight direction, follow-up control of high magnification optical drive, rapid automatic focusing, highly sensitive recording and detection equipment, industrial robot, bionic prosthesis, etc., hollow cup motor can well meet its technical requirements.
- Products requiring stable and lasting driving of driving elements. For example, all kinds of portable instruments and meters, personal portable equipment, instruments and equipment for field operation, electric vehicles, etc. with the same set of power supply, the power supply time can be more than doubled.
- Various aircraft, including aviation, aerospace, aircraft model, etc. Using the advantages of light weight, small volume and low energy consumption of hollow cup motor, the weight of aircraft can be reduced to the greatest extent.
- All kinds of civil electrical appliances and industrial products. Using the hollow cup motor as the actuator can improve the product grade and superior performance.
- Taking advantage of its high energy conversion efficiency, it is also used as a generator; Using its linear operation characteristics, it is also used as a tachogenerator; Equipped with reducer, it can also be used as torque motor.
With the progress of industrial technology, the strict technical conditions of various electromechanical equipment put forward higher and higher technical requirements for servo motor. At the same time, the application scope of hollow cup motor has completely separated from the limitations of high-end products, and is rapidly expanding its application scope in low-end products such as general civil products, so as to widely improve product quality. According to relevant statistics, hollow cup motors have been mature and applied to more than 100 civil products in industrial developed countries.
