Micro motors are commonly used in control systems or transmission machinery loads to perform functions such as detection, analysis, amplification, execution, or conversion of electromechanical signals or energy.

[0003] Many micro motors use long shafts, but due to their long length, the stability of the long shafts during rotation is difficult to guarantee, which can affect the performance and working status of the equipment using the micro motor. Therefore, an electric micro motor structure is proposed here. Utility Model Content

When the micro motor is energized, the current passing through the coil of the stator 6 generates an electromagnetic force that interacts with the magnetic field of the rotor 7, forming a rotational torque, which causes the rotor 7 and the shaft 4 to rotate.

[0017] The rotating shaft 4 is connected to the upper middle part of the housing 1 by a bearing, and the connecting sleeve 8 is connected to the upper end of the housing 1 by screws. The connecting sleeve 8 can be easily disassembled from the housing 1.

The second support plate 12 can support the rotating shaft 4, making the rotating shaft 4 more stable when rotating.

[0019] Working principle: The micro motor operates using an external power supply. The rotor 7 has permanent magnets. When the micro motor is energized, the current passing through the coil of the stator 6 generates an electromagnetic force that interacts with the magnetic field of the rotor 7, forming a rotational torque, which causes the rotor 7 and the shaft 4 to rotate. The second support plate 12 provides support for the shaft 4, making the shaft 4 more stable during rotation. The first support plate 9, the connecting rod 11, and the second support plate 12 can be easily disassembled and assembled.
