Application Project Experience
Metallurgy Project Experience
The converter steelmaking process at Henan Yaxin Iron and Steel Plant requires precise control systems for quality molten steel production. The mechanical tilting converter can rotate 360° continuously, driven by 4 sets of 90KW variable frequency motors with precise positioning and speed regulation.
Solution: The 4 rigidly connected motors use master/slave control with internal communication for absolute synchronization. The host inverter adjusts speed and torque output while slave inverters follow the torque response, eliminating nodding and shaking issues.
Rolling Mill Application
Our regenerative drive was successfully implemented in a 20-roll reversible mill project featuring 4 motors (1900kW main winding, 2x 2000kW winding, and 250kW unwinding). The system achieved tension control accuracy under 1% with maximum rolling line speed of 600m/min.
Mine Hoist Experience
Our drive system was selected by SIEMAG TECBERG group for shaft hoisting technology, meeting strict requirements for low harmonics and high torque at low frequencies for safety-critical operations.
Motor Test Bench Project
Our system features two motors (MUT and DM) with controller-managed speed and torque, enabling motor durability testing, temperature rise analysis, overload performance, and real-time display of operational parameters.
National Key Project - Xiangyanghong Research Ship
Our drive system was selected for the world-leading marine long-line winch application, meeting strict electromagnetic interference requirements with harmonics under 3% to protect sensitive electronic equipment.

Frequently Asked Questions
What is direct torque control?
Direct Torque Control (DTC) is a method used in variable frequency drives to control torque and flux directly without requiring complex coordinate transformations.
What are the benefits of direct torque control?
- Fast torque and flux response
- High efficiency with minimized switching losses
- No overshoot in step response
- No dynamic coordinate transforms required
- No separate modulator needed
- No PI current controllers requiring tuning
- Low audible machine noise
- 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 appropriate insulation (800V for 200V class, 1600V for 400V class).
What are common reasons for motor failure?
According to studies: 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.
