Application Experience
Metallurgy Project - Henan Yaxin Iron and Steel Plant
The converter steelmaking process requires precise control of multiple parameters. Our system provides accurate process parameter detection and high-level automatic control to ensure molten steel quality and output.
Converter Requirements
- 360° continuous rotation with precise positioning
- Speed regulation according to process requirements
- Maximum safety and reliability during operation
- Flexibility to buffer shock load and torsional vibration
Solution
Implemented master/slave control for 4 rigidly connected 90kW motors, with data transmission between drives through internal communication. The host inverter adjusts speed and torque output while slave inverters follow torque response, eliminating "nodding" and "shaking" issues.
20-Roll Reversible Mill Project
Implemented regenerative drive system with 4 motors (1900kW main winding, 2x2000kW winding, 250kW unwinding) at 690VAC input. Achieved tension control accuracy <1% with maximum rolling line speed of 600m/min.
Mine Hoist Experience
Developed solution for SIEMAG TECBERG group with low harmonics and high torque at low frequency, meeting strict safety requirements for shaft hoisting systems.
Motor Test Bench Project
System features include motor durability testing, temperature rise analysis, field weakening performance evaluation, and real-time display of voltage, current, torque, speed, power, and efficiency.
Frequently Asked Questions
What is direct torque control?
Direct Torque Control (DTC) is a method that provides fast torque response without needing complex coordinate transforms. It maintains torque and flux within defined bands through hysteresis control.
What are the benefits of direct torque control?
- Fast torque and flux changes by adjusting references
- High efficiency with minimized switching losses
- No overshoot in step response
- No dynamic coordinate transforms required
- No separate modulator needed
- No PI current controllers or tuning required
- Low audible noise due to random switching
- Automatic compensation for DC voltage variations
What type of motor is compatible with inverters?
Three phase AC induction motors are compatible, preferably inverter-grade motors with 800V insulation for 200V class inverters or 1600V insulation for 400V class inverters.
What are common reasons for motor failure?
According to EPRI Power Industry Study: 41% bearing related, 37% stator related, 10% rotor related, and 12% other causes.
How do you select a VFD?
Consider motor specifications, application requirements, environmental conditions, and required features like communication protocols and control modes.
