Problems solved by technology

[0003] For example, on the mechanical arm of a robot, because there are too many sensors on the arm, the vibration of the motor will affect the stable operation of other precision instruments. However, the existing technology is not effective in detecting and processing this vibration.

Embodiment Construction

[0019] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0020] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the ...

Abstract

The present invention provides a jitter detection processing system and a method for a miniature motor. The jitter detection processing system for the miniature motor comprises an STM32 control chip, a detecting unit, a first signal processing unit, a sampling module, a second signal processing unit, a first oscilloscope, a current amplification circuit, a second oscilloscope, a vector signal analyzer, a computer LABVIEW module and a power supply. The detection unit comprises a current sensor and a displacement sensor. The first signal processing unit comprises a first follower circuit, a first controllable amplifying circuit, a second follower circuit, a first band-pass filtering module and a first A/D module. The second signal processing unit comprises a multi-path PWM module, a second controllable amplifying circuit, a second band-pass filtering module and a second A/D module. Based on the above-described techniques, the jitter parameter signal of the motor is compared with a reference signal, so that the jitter degree of the motor is determined. Furthermore, whether an anti-phase current needs to be applied to the stator winding of the motor to eliminate the internal noise harmonic influence of the motor or not can be determined.

Description

technical field [0001] The invention relates to motor detection technology, in particular to a vibration detection and processing system and method for micro motors. Background technique [0002] Micro motor, the full name of "micro motor", refers to a motor with a diameter of less than 160mm or a rated power of less than 750mW. Micromotors are often used in control systems or transmission mechanical loads to realize functions such as detection, analytical operation, amplification, execution or conversion of electromechanical signals or energy. [0003] For example, on the mechanical arm of a robot, because there are too many sensors on the arm, the vibration of the motor will affect the stable operation of other precision instruments. However, the existing technology is not effective in detecting and processing this vibration. Contents of the invention [0004] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of t...
