ABB Drives is a core business unit of ABB, focusing on the research, development, manufacturing, and sales of a full range of motor control and energy efficiency optimization equipment. Its main products include low-voltage/medium-voltage frequency converters, soft starters, servo drives, and related motor and control systems. Its core technology lies in achieving precise control of AC/DC motor speed, torque, and position through advanced algorithms such as direct torque control and vector control. It also deeply integrates energy management, predictive maintenance, and digital connectivity functions, and is widely used in industry, infrastructure, and transportation, aiming to improve equipment performance, reduce energy consumption, and empower industrial automation and digital transformation.

The core advantage of the ABB Drives series lies in its deep integration of superior control performance, top-notch energy efficiency, and forward-looking digital capabilities: its unique direct torque control technology achieves millisecond-level torque response, meeting the most demanding dynamic load requirements; the entire series is designed with high efficiency in mind, combined with energy-saving architectures such as a common DC bus, significantly reducing system energy consumption; at the same time, the products have built-in predictive maintenance and cloud-ready functions, transforming drive devices into intelligent data nodes, providing full lifecycle services through the ABB Ability™ platform, delivering comprehensive value to customers in improving productivity, reducing operating costs, and achieving digital transformation.

The core feature of the ABB Drives series is its comprehensive solution integrating high-performance control, superior energy efficiency, and deep intelligence: it offers a product line from micro to large, covering all power and voltage levels; it features leading algorithms such as direct torque control for precise and rapid motor regulation; the entire series is designed with high efficiency and energy saving, significantly reducing system energy consumption; and it deeply integrates digital functions, supporting predictive maintenance, cloud connectivity, and industrial IoT integration, meeting diverse needs from basic speed regulation to complex automation systems.

The core application of the ABB Drives series is to provide precise speed, torque, and position control for various industrial motors, thereby achieving three key objectives: optimizing process flows (such as improving production line speed accuracy and coordinating multi-machine synchronous operation), significantly reducing energy consumption (especially for variable torque loads such as fans and pumps), and achieving intelligent operation and maintenance (ensuring equipment reliability and production efficiency through built-in monitoring and predictive functions). It is widely used in critical sectors such as manufacturing, energy, transportation, and building automation.

Direct Torque Control (DTC) is a high-performance control technology for AC motors. It detects the motor flux linkage and torque in real time and directly compares them with a given value. Using a hysteresis controller, it generates a switching signal to directly control the inverter, achieving a fast and precise dynamic response to motor torque at the millisecond level. This technology eliminates the need for complex coordinate transformations and PWM modulators, has a simple structure, and is less dependent on motor parameters. It is particularly suitable for industrial applications such as cranes and rolling mills that require rapid start-up, braking, and torque surges.
