Siemens drives are electronic devices used to control the speed, torque, and direction of electric motors. They are an essential part of industrial automation, helping improve energy efficiency, precision, and machine performance. Siemens offers a wide range of AC and DC drives under the SINAMICS and MICROMASTER series, designed for different motor types and applications.
The main types of Siemens drives include:
-
SINAMICS V-series (V20, V60, V90) – Compact and cost-effective AC variable frequency drives (VFDs) designed for general-purpose applications like pumps, fans, and conveyors. The V20 is known for its simplicity and reliability, while the V90 is optimized for servo motion control systems.
-
SINAMICS G-series (G110, G120, G120C, G130, G150) – General-purpose and modular drives for variable-speed control of motors in industrial environments. The G120 family is widely used with Siemens PLCs for efficient motor control, offering features like regenerative braking, safety functions, and energy monitoring.
-
SINAMICS S-series (S120, S210, S150) – High-performance servo drives designed for precise motion control, robotics, packaging machines, and CNC systems. These drives support multi-axis synchronization and high dynamic response.
-
SINAMICS DC and DC Master Drives (DME, DCM) – Used for controlling DC motors in heavy-duty industries like steel plants, paper mills, and cranes where high torque is required at low speeds.
All Siemens drives are configured using TIA Portal or STARTER software and support PROFINET, PROFIBUS, and Modbus communication for seamless integration with S7-1200 or S7-1500 PLCs.
In simple terms, Siemens offers V-series drives for simple control, G-series for general industrial use, S-series for high-precision servo motion, and DC drives for heavy-duty torque applications. This complete drive portfolio ensures Siemens can meet the power and performance needs of any automation system.
Siemens offers a wide range of drives under its SINAMICS family, designed to meet different industrial automation and motion control needs. The main types include Variable Frequency Drives (VFDs), Servo Drives, DC Drives, and Distributed Drives. The most common ones are the SINAMICS low-voltage frequency drives such as the G120, G120C, and V20 series, which control the speed of AC motors. These drives are used in pumps, fans, conveyors, and compressors where energy efficiency and process control are important. Siemens also uses the term SIMOVERT for its AC inverters, which perform similar motor control functions.
For high-precision motion control, Siemens offers SINAMICS Servo Drives like the V70, V90, and S210 series. These are ideal for robotics, CNC machines, and packaging systems that require accurate position and speed control. For DC motor applications, SINAMICS DC Drives provide reliable power conversion for both simple and complex setups. Siemens also provides Distributed Drives such as G115D and G120D, which integrate the drive and motor in one compact unit for decentralized systems like conveyor belts. In short, Siemens drives cover every need — from basic speed control to advanced multi-axis motion — offering efficient, scalable, and intelligent solutions for all types of automation environments.
