All essential components of the stepper motor with controller are housed in a single enclosure. This makes the entire assembly more compact and requires less space.
Because the components are integrated, there is no need to install and wire separate drivers and controllers, which simplifies and speeds up installation and setup.
Less wiring means greater reliability and fewer potential points of failure. It also reduces electromagnetic interference (EMI) that can be caused by long cable runs.
Advanced features such as microstepping, torque control, speed control, and fault diagnosis are built in.
Integration also helps reduce overall costs, as fewer separate components need to be purchased and assembled.
With fewer separate components, maintenance is often easier because there are fewer potential sources of error and problems can be diagnosed more quickly.
Gunda Automation’s MotorFinder helps you select stepper motors with integrated controllers, axis systems, and complete drive solutions. Using real motion data as well as defined masses and forces, suitable drives can be selected quickly, precisely, and transparently.
In just a few steps, the axis system, motion profile, and load data are entered. The tool then calculates suitable stepper motors with integrated controllers and clearly displays the results in a torque-speed curve.

Stepper motors with integrated control combine the motor, power electronics, and positioning control into a single compact unit. This significantly reduces wiring effort, control cabinet size, and commissioning time. Integrated stepper motors are being used more and more frequently, particularly in mechanical engineering, industrial automation, positioning systems, and decentralized drive concepts.
In this FAQ, we answer the most important questions about stepper motors with integrated control, Industrial Ethernet, PLC connectivity, safety functions, gear options, and selecting the right drive solution.
A stepper motor with integrated control combines the motor, power electronics, and positioning control in a single compact housing. Unlike traditional solutions, there is no need for an external stepper motor controller in the control cabinet. This significantly reduces wiring effort, space requirements, and installation costs. Stepper motors with integrated control are frequently used in positioning systems, packaging machines, handling systems, and modern automation solutions.
The integration of the motor, controller, and power electronics creates a compact all-in-one solution. Installation effort is reduced, commissioning is accelerated, and space requirements in the control cabinet are minimized. At the same time, the number of potential sources of error is reduced due to fewer cables and connectors. Modern stepper motors with integrated control also support Industrial Ethernet protocols and can be easily integrated into existing automation systems.
Stepper motors are particularly well-suited for precise positioning tasks at moderate speeds and offer an attractive price-performance ratio. Servo motors are primarily used in highly dynamic applications requiring high acceleration, high speeds, and maximum control accuracy. For many positioning tasks in mechanical engineering, stepper motors with integrated controllers represent a cost-effective alternative to servo drives.
Modern stepper motors with integrated controllers support industrial communication interfaces such as Profinet, EtherCAT, EtherNet/IP, CANopen, or Profibus. This allows the drives to be integrated directly into PLCs and automation systems. The choice of the appropriate interface depends on the control architecture used and the application requirements.
Profinet is frequently used in Siemens-based automation solutions and enables seamless integration into the TIA Portal. EtherCAT is characterized by particularly short cycle times and very high performance in multi-axis systems. Both systems enable reliable communication between the PLC and the drive, but differ in terms of real-time capability, network architecture, and typical areas of application.
EtherCAT is one of the most powerful Industrial Ethernet systems and is particularly well-suited for applications with short cycle times and synchronized multi-axis systems. Stepper motors with EtherCAT enable fast real-time communication between the controller and the drive and are frequently used in mechanical engineering, packaging systems, and complex automation systems.
Yes. Many integrated stepper motors have been specifically designed for direct PLC connection. Motion commands, diagnostic data, and status information can be exchanged directly between the controller and the drive via Industrial Ethernet or fieldbus interfaces. This makes it possible to implement modern machine designs particularly efficiently.
Typically, integrated stepper motors have separate power supplies for the motor and the logic. Often, 24 VDC is used for the control electronics and 24 to 48 VDC for the motor power supply. The separate power supplies enable flexible machine and safety designs and increase operational reliability.
A stepper motor with a gearbox is used when higher torques, lower output speeds, or particularly precise positioning are required. Using a planetary gearbox can significantly increase the available torque and improve resolution. Typical applications include rotary tables, dosing systems, positioning systems, and handling axes.
Selecting the appropriate size depends on the required torque, the masses being moved, the desired dynamics, and the installation conditions. NEMA17 motors are suitable for compact applications, while NEMA23 and NEMA24 drives cover many classic automation tasks. NEMA34 stepper motors are used when high forces and torques are required.
Depending on the model, integrated stepper motors feature safety functions such as STO (Safe Torque Off). This function reliably prevents the generation of torque and enables the motor to be safely shut down. This allows modern safety concepts in mechanical engineering to be efficiently implemented.
STO stands for Safe Torque Off and refers to a safety function for safely shutting down the motor torque. When the STO function is activated, the motor can no longer generate torque. This prevents unintentional startup and increases the safety of machines and systems.
Depending on the model, stepper motors with integrated control are available in various protection ratings. Many industrial drives come standard with IP40 and are also available with higher protection ratings, such as IP54, as an option. This makes them suitable for demanding industrial environments with increased requirements for dust and contact protection.
M12 connectors have established themselves as an industry standard. They enable quick installation, secure signal transmission, and high reliability even under demanding environmental conditions. At the same time, they significantly simplify maintenance and service.
Typical applications include positioning systems, packaging machines, laboratory automation, medical technology, dosing systems, handling systems, conveyor systems, CNC applications, and general automation tasks in mechanical engineering. Wherever precise movements, a compact design, and easy integration are required, integrated stepper motors offer significant advantages.
The trend toward decentralized machine designs and Industry 4.0 applications means that more and more functions are being integrated directly into the drive. Stepper motors with integrated control significantly reduce the effort required for planning, wiring, and commissioning. At the same time, modern interfaces such as Profinet, EtherCAT, or CANopen enable direct communication with the machine controller and lay the foundation for flexible automation solutions.
When selecting a suitable stepper motor, torque, speed, acceleration, load mass, and installation space should be taken into account. A professional drive design helps to realistically evaluate reserves and loads. With the Gunda MotorFinder, you can quickly and transparently size suitable stepper motors, gearheads, and drive systems.
