Abstract

The invention relates to an Android-based asynchronous motor system capable of remotely monitoring stator current. The system comprises a host computer, a remote mobile monitoring terminal based on anAndroid system, three alternating current sensors installed on an asynchronous motor seat housing, and a monitoring system which is based on a single-chip microcomputer and is arranged on the asynchronous motor seat housing. The real-time remote monitoring of the running state of an asynchronous motor in a mobile phone is achieved, and the stability and safety of the motor in an enterprise working operation are improved. The Android-based remote mobile monitoring terminal, the host computer and the monitoring system are used to monitor different change values of the current of an asynchronousmotor stator winding, thus the current running state of the stator windings of the asynchronous motor can be monitored remotely in real time, the stability and safety of motor operation are improved.A user can use the remote mobile monitoring terminal based on Android to remotely monitor the current operation parameters of the asynchronous motor stator winding and timely find a fault, and the normal production of an enterprise is escorted.

Description

technical field [0001] The invention relates to the production and manufacture of motors, in particular to an Android-based asynchronous motor system capable of remotely monitoring the stator current. Background technique [0002] It is very important to maintain a stable and symmetrical three-phase current in the stator winding of an asynchronous motor when the motor is running under load. When the three-phase current is unbalanced, the positive sequence voltage produces a positive electromagnetic field torque, which is positive, as the driving torque, and the negative sequence voltage produces a negative electromagnetic torque, which is negative, which acts as a brake. Thereby reducing the total electromagnetic torque. [0003] When the motor is running symmetrically, there is a uniform circular rotating magnetic field inside the motor, and its electromagnetic torque is constant. When running asymmetrically, the trajectory of the synthetic magnetomotive force is an ellip...
