The converter steelmaking process of Henan Yaxin Iron and Steel Plant's steelmaking plant is relatively complex, with many detection parameters and frequent equipment movements. The accuracy of process parameter detection and the level of automatic control are directly related to the quality and output of molten steel.

• The mechanical tilting converter can continuously rotate 360°
• Driven by 4 sets of 90KW variable frequency motors
• Must have maximum safety and reliability during operation
• Should have good flexibility to buffer shock load and torsional vibration

Since these 4 motors are rigidly connected, the speeds of all motors are required to be absolutely synchronized. The transmission of the 4 motors adopts master/slave control, with data transmitted between the 4 drives through internal communication.

About rolling mill in metallurgy, last year we did one project in a steel plant in Henan province, it is our regenerative drive application in 20-roll reversible mill project. In total of 4 motors: 1 pcs of 1900kW main winding motor, 2 pcs 2000kW winding motors and one 250kW unwinding motor.

SIEMAG TECBERG group is a leading supplier of shaft hoisting technology. The main request for the drives is low harmonics and high torque in low frequency because in order to keep safety environment, the system must work at very low speed in low frequency.

The electric motor test bench includes 2 motors, one is MUT (Motor under test), the other is DM (Driving motor). During the test, the controller controls the motor speed and torque. One motor works under motoring mode, the other motor works under generator mode.

1. Power unit: To make sure the motor constant torque output, keep DC bus voltage stable, and reduce the interference in the site, select Inomax AFE (Active front End) as rectifier.

2. Control unit: The rectifier control unit (RCU) and inverter control unit (ICU), through drive cable, three modules output uvw at the same time through the reactor and then concatenate the output to drive a single motor.

• Significant energy saving effect
• Good bidirectional loading characteristics
• Wide range of speed adaptation
• High torque response speed
• Provide anti-drag capability

This project is a high-end marine long-line winch, world leading level. Due to the large number of precision electronic equipment used in marine detection, strict requirements are placed on the drive system of the winch, and the expected harmonics are less than 3%.

Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.

• Torque and flux can be changed very fast by changing the references
• High efficiency & low losses - switching losses are minimized
• The step response has no overshoot
• No dynamic coordinate transforms are needed
• No separate modulator is needed
• There are no PI current controllers
• The switching frequency of the transistors is not constant
• Due to the hysteresis control the switching process is random by nature
• The intermediate DC circuit's voltage variation is automatically taken into account
• Synchronization to rotating machine is straightforward due to the fast control

Inverter motor type must be a three phase AC induction motor. Preferably, you should use an inverter-grade motor that has 800V insulation for 200V class inverters, or 1600V insulation for 400V class inverters.

The EPRI Power Industry Study by General Electric in 1985 offered the following causes based on 6,000 utility motor failures: 41% were bearing related, 37% were stator related, 10% were rotor related and 12% were other causes.
