I. Internal structure of hollow cup motor Hollow cup motor is a new type of electric motor with a complex structure, including rotor, stator, drive circuit and many other components, of which the most important is the hollow cup rotor. The hollow cup rotor is a hollow cylindrical structure, which consists of several isolated motor coils inside, while the shell is made of highly conductive material. At the same time, there are also motor coils inside the stator, and the hollow cup rotor is continuously rotated by changing the direction of the electromagnetic field through the AC power supply. 2.The electromagnetic principle of hollow cup motor The working principle of hollow cup motor is based on the law of electromagnetic induction. When the current passes through the motor coil, a magnetic field will be generated around it, and the strength of the magnetic field generated between neighboring coils is different. In this case, the neighboring coils will interact with each other, and this interaction will cause the hollow cup rotor to rotate. Specifically, when current flows through a coil, a certain magnetic field is generated inside the coil. And since the hollow cup rotor also has a number of motor coils inside, the magnetic fields generated between these coils will interact with each other, thus creating a gravitational force and a repulsive force. By constantly changing the direction of the current, the direction of these gravitational and repulsive forces can be constantly changed, thus allowing the hollow cup motor to constantly rotate. 3. The application fields and future development direction of hollow cup motor Hollow cup motor is a very flexible motor, also called coreless dc motor,suitable for energy, aviation, robotics, medical equipment and other fields, widely used in transmission and control of high precision requirements of the occasion. In the future, with the popularization of various electronic devices and the development of robotics, hollow cup motors will have a wider range of applications. At the same time, the improvement of performance indicators and cost-effectiveness will also be the key to the future development of hollow cup motor.
