Description

Technical Field

[0001] The utility model relates to the field of motor shafts, in particular to a rotor structure for a motor. Background Art

[0002] The motor rotor is the rotating part in the motor. The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. In order to extend the service life of the rotor, a high-strength rotor structure is required. Among them, the "rotor structure for a stepper motor" disclosed in the application number "CN202122894278.6" is also an increasingly mature technology. It "through the setting of the connecting mechanism, the connecting mechanism can connect the rotor cores, and through the setting of the rotating parts, windings, clamps and limit tubes, the windings and limit tubes are used together to assemble several groups of rotor cores into a rotating body. The clamps can fix the windings, thereby improving the stability of the rotating body and extending the rotor core. The service life is long, and it is convenient for people to use. The whole device has a simple structure and is easy to operate, which increases the practicality of the whole rotor structure. However, the rotor structure still has the following defects during use: the rotor structure can indeed improve the stability of the rotor by coordinating the rotating parts with the winding, the clamping parts, the limit tube and other structures, but the above structure is relatively complex, so it may cause the parts to fall off when the rotor rotates at a high speed. Based on this, it is necessary to provide a rotating shaft that can improve the stability of the rotor structure and has a simple structure. In addition, the rotor structure is weak in strength, so long-term use may cause the rotor structure to be deformed and damaged. Based on this, it is necessary to provide a rotor structure that can significantly improve the structural strength and extend the service life. Utility Model Content

[0013] 2. When the rotor body rotates, the rotor body made of silicon steel can initially enhance its own strength and avoid deformation. At the same time, the first magnetic steel slot and the second magnetic steel slot cooperate with a number of arc-shaped triangular structure reinforcement holes to further enhance the structural strength of the rotor assembly.
