Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0036] For the existing motor equipment, AC motors are generally used, but in special cases, the air volume of the whole machine cannot be increased. In order to increase the air volume while ensuring that the structure of the whole machine does not move, only variable frequency DC motors can be used. However, the use of variable frequency DC motors will cause problems with the failure rate of the motor.

[0037] In this example, a motor operation fault monitoring method is proposed to monitor motor faults, such as figure 1 As shown, the method may include:

Abstract

The present invention provides a motor operation fault monitoring method and device, wherein the method includes: acquiring voltage dynamic data and current dynamic data of the target motor equipment; determining the target according to the voltage dynamic data and the current dynamic data The type of failure of the electrical equipment. The above-mentioned solution can solve the problem that the existing DC motor used as the motor equipment has a relatively high failure rate, which leads to the short service life of the motor equipment, and achieves the technical effect of effectively improving the service life of the motor equipment and the reliability of the unit.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a method and device for monitoring motor operation faults. Background technique [0002] At present, under the condition that the air volume of motor equipment (such as: central air conditioner, household air conditioner, fresh air system, etc.) is gradually increasing, ordinary AC motors cannot meet the requirements of speed and air volume. Therefore, DC motors are generally used as the motor type of motor equipment. , and generally driven by an external motor. Furthermore, through multiple monitoring, it is found that the failure rate of the external motor drive is higher than that of the built-in drive AC motor. [0003] For how to reduce the failure rate of motors, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a motor operation fault monitoring method and device, so as to reduce the f...
