Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] Such as figure 1 and figure 2 As shown, the present invention provides a rotor assembly, which is suitable for motors. The rotor assembly includes: a rotating shaft 1, an inertia disk 2 and a splined hub 3 that are sequentially sleeved on the rotating shaft 1, and the inertia disk 2 can be moved along the extension direction of the rotating shaft 1. Set in motion, the spline hub 3 is fixedly connected to the rotating shaft 1, and the inertia disk 2 is detachably connected to the spline hub 3; the rear end cover 4, one end of the rotating shaft 1 is rotatably installed on the rear end cover 4, and the rear end The cover 4 is located on the side of the inertia disk 2 away from the splin...

The invention provides a rotor assembly and a motor with the rotor assembly, the rotor assembly is suitable for the motor, the rotor assembly comprises a rotating shaft, and an inertia disc and a spline hub which are sequentially arranged on the rotating shaft in a sleeving manner, the inertia disc can move along the extension direction of the rotating shaft, the spline hub is fixed on the rotating shaft, and the inertia disc is detachably connected with the spline hub; a rear end cover is located on the side, away from the spline hub, of the inertia disc, and one end of the rotating shaft is rotatably arranged on the rear end cover in a penetrating mode; one side, close to the inertia disc, of the rear end cover is provided with a coil, and the inertia disc is made of a magnetic metal material; one side, close to the inertia disc, of the rear end cover is provided with an elastic piece; and / or the manufacturing material of the spline hub comprises a magnetic material; the inertia disc is separated from the spline hub through magnetic acting force generated by electrifying the coil; or the inertia disc is connected with the spline hub through the elastic acting force of the elastic piece and / or the magnetic acting force of the spline hub, so that the problem that the rotational inertia of a servo motor in the prior art is relatively complex to adjust is solved.
Description
technical field [0001] The present invention relates to the technical field of motors, in particular to a rotor assembly and a motor having the same. Background technique [0002] The motor is a common power source with a wide range of applications, usually including multiple types, such as stepper motors, servo motors, etc.; among them, the servo motor drives the control object, speed and speed by converting the voltage signal into torque and speed. The position is usually used as an important part of the servo system to realize the power output. [0003] In different use environments, there are different requirements for the moment of inertia output by the servo motor. The moment of inertia of the servo motor in the prior art is mostly a fixed value, so in the face of different use requirements, only through Replace different servo motors to achieve. [0004] In this regard, someone proposed a rotor assembly of a servo motor that adjusts the inertia of the motor side by ...
