Metallurgy Project Experience
Converter steelmaking process at Henan Yaxin Iron and Steel Plant required precise control for quality molten steel production. The system features:
- 4x 90KW variable frequency motors for 360° continuous rotation
- Accurate positioning at any point with speed regulation
- Safety interlocking with oxygen lance, ladle car and fume hood
- Fault-tolerant operation to complete current steelmaking cycle during failures
- Shock load and torsional vibration buffering
Solution Implementation
Master/slave control configuration with internal communication between drives ensures absolute synchronization of all 4 motors. The host inverter adjusts speed and torque output 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 directly regulates torque and flux without requiring complex coordinate transformations. It provides fast torque response and high efficiency by minimizing switching losses.
What are the benefits of direct torque control?
- Fast torque and flux response to reference changes
- 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
- Random switching process reduces audible noise
- Automatic compensation for DC voltage variations
- Fast 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 inverters or 1600V insulation for 400V class inverters. Always match the inverter to the motor's specifications.
What are common reasons for motor failure?
Industry studies show: 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 braking, communication protocols, and control precision.
