Core Technology

Direct Torque Control (DTC) Technology: The ACS6000 system’s motor control platform is based on ABB’s award-winning Direct Torque Control (DTC) technology, which enables real-time and precise control of motor torque and speed, achieving unprecedented high performance in the medium-voltage drive field. This technology can quickly respond to control commands under various operating conditions, ensuring stable motor operation and making the drive system control more instantaneous and smooth.

Integrated Gate Commutation Thyristor (IGCT): The module uses IGCTs as power semiconductor devices, which have advantages such as low conduction loss, high blocking voltage, and fast switching capabilities, making them particularly suitable for high-power medium-voltage applications. The use of IGCTs significantly reduces the number of components in the system, simplifies the circuit structure, and improves system reliability and efficiency.

Application Scenarios

Metallurgical Industry: In rolling mill drive systems, the S-073N phase module ensures stable torque output by precisely controlling the motor’s power supply phase, enabling the rolling mill to produce high-quality steel at a constant speed. In cases where multiple motors are used to drive the rolling mill, the module ensures phase synchronization between the motors, preventing rolling force fluctuations caused by phase inconsistencies and improving the rolling accuracy and surface quality of the steel.

Mining Industry: In large equipment such as crushers and hoists, the module can monitor the motor’s operating status in real time and adjust the phase according to load changes, ensuring sufficient torque output while preventing motor damage due to overload or underload. For hoists, the module ensures stable phase during the lifting and lowering of heavy objects, achieving smooth lifting and lowering operations and improving the safety and efficiency of mining production.

Chemical Industry: In equipment such as pumps and compressors in chemical production, the module optimizes the motor’s power supply phase, improving motor efficiency and reducing energy consumption. When chemical pumps transport different media, the load characteristics change; the module can adaptively adjust the phase to ensure stable pump operation. For compressors, precise phase control helps reduce vibration and noise, extending the equipment’s service life.
