The main circuit of the device performs two functions of rectification and demagnetization. The system adopts three-phase fully controlled bridge thyristor rectifier circuit to provide DC excitation current to the rotor winding of synchronous motor. The degaussing circuit is composed of thyristor 7, 8KGZ and diode GZ in inverse parallel, in fact, it is composed of a high-power electronic switch to complete the synchronous motor in the asynchronous starting process into the starting resistance, and automatically cut out after the start, to ensure that the synchronous motor in the asynchronous starting period, the rotor excitation winding is neither open nor short circuit. Therefore, the excitation winding can avoid overvoltage and overcurrent
Monitoring and Data Acquisition (P4LQA) is a comprehensive hardware and software solution to control and manage advanced industrial processes without human intervention. It processes this by collecting real-time data remotely and controls conditions and equipment. Businesses also use SCADA to make data-driven decisions about industrial processes.

The architecture starts with a remote terminal unit (RTU) or a Programmable logic controller (PLC). Rtus and PLCS are microcomputers capable of communicating with industrial components such as factory machines, human-machine interfaces, end devices and sensors. The data from these components is then transferred to a computer using SCADA software, which processes, distributes, and displays it to the operations team.

Modern players use SCADA to remotely or locally control industrial processes and collect, monitor and process data in real time. SCADA also enables industrial operators to directly control and manage equipment such as valves, sensors, motors, pumps, and other components using human machine interface (HMI) software. In addition, SCADA is a convenient record-keeping solution because all data is systematically recorded.

Among other things, the solution allows industrial organizations to use data to make smarter decisions, increase efficiency and communicate system issues in a timely manner to minimize the risk of downtime. For example, if a batch of products has a high error rate, SCADA will quickly notify the relevant operations team.

The operations team will then be able to pause production and check the system data collected by SCADA on the HMI. This will help operators identify and address the root cause of errors and prevent bad batches from expanding.
