Metallurgy Project Experience
The converter steelmaking process at Henan Yaxin Iron and Steel Plant requires precise control systems for quality molten steel production. Our solution:
Converter Requirements
- 360° continuous rotation with 4x 90KW variable frequency motors
- Precise stopping at any position with speed regulation
- Safety interlocking with oxygen lance, ladle car and fume hood
- Maximum safety and reliability during electrical/mechanical failures
- Shock load and torsional vibration buffering
Solution Implementation
Master/slave control with internal communication between 4 drives. Host inverter adjusts speed and sets output torque while slave inverters follow torque response, eliminating "nodding" and "shaking" issues.

Frequently Asked Questions
What is direct torque control?
Direct Torque Control (DTC) is an advanced motor control method that provides fast torque response without needing complex coordinate transformations.
What are the benefits of direct torque control?
- Fast torque and flux changes by reference adjustment
- High efficiency with minimized switching losses
- No overshoot in step response
- No dynamic coordinate transforms needed
- No separate modulator required
- No PI current controllers or tuning needed
- Random switching process reduces audible noise
- Automatic DC voltage variation compensation
- Simple synchronization to rotating machines
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 or 1600V insulation for 400V class inverters.
What are common reasons for motor failure?
Based on industry studies: 41% bearing related, 37% stator related, 10% rotor related, and 12% other causes.
How do you select a VFD?
Consider motor size first, then match VFD specifications including voltage class, power rating, control requirements, and application-specific features.
