Embodiment Construction

[0040] The technical solutions of the present invention will be described in detail below through embodiments with reference to the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention.

[0041] The term "and / or" in this article is just an association relationship describing associated objects, which means that there may be three relationships, for example, A and / or B, which can mean: A exists alone, B exists alone, and A and B exist simultaneously. In the three cases of B, the term " / and" in this article is to describe another associated object relationship, which means that there can be two relationships, for example, A / and B, which can mean: there is A alone, and there are two cases of A and B alone , In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

Description

technical field [0001] The invention relates to the technical field of motors, and more specifically, the invention relates to a motor system with a precisely controllable output speed. Background technique [0002] In the control of the motor in the prior art, the adjustment of the control strategy is usually used for high-precision control, and the current closed-loop control loop is mostly used for control. The difference in the output of the motor leads to the decrease of the control accuracy of the motor. The parameter changes of the motor include the perturbation of the motor parameters, the change of the friction resistance of the motor, the change of the rotational inertia, the noise of the current sensor and other factors. It will also cause a decrease in motor control accuracy. [0003] In the prior art, the output speed of the motor is also adjusted by improving the internal structure of the motor. For example, a high-precision and controllable servo motor, the a...
