Detection device and method under operation states of loads on motor transmission systems

Abstract

The invention discloses a detection device and method under operation states of loads on motor transmission systems. The device comprises a first magnet (1), a second magnet (2), an induction coil (3)and a control module (5), wherein the first magnet (1) and the second magnet (2) are used for establishing a magnetic field under an operation state of a load on a motor; the induction coil (3) is used for inducing a change amount of the magnetic field; the control module (5) is used for determining whether the change amount is greater than or equal to a first set value, and determining that a connection state between the motor and the load is abnormal if the change amount is greater than or equal to the first set value. According to the device and method, the problem that the reliability isreduced due to the long-term using of to-be-dismounted application environments and overall systems of motors and loads in the prior art, and the effect of enhancing the reliability is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to a detection device and method for a motor transmission system under a load running state, in particular to a transmission control system for detection of a load running state and a corresponding detection method. Background technique [0002] The motor is the core component of energy exchange. With the continuous expansion of applications and the continuous improvement of the reliability of the whole system, the application environment where the motor and the load need to be disassembled and the reliability of the whole system will decrease with long-term use. Problems (for example: wear, corrosion and deformation of the connection between the load and the motor shaft, and the detachment of the fixing screws will lead to reduced reliability and failure of the whole machine function), and the motor drive system puts forward higher requirements for early predicti...
