Stepper motor with integrated controller
Stepper motors with integrated controller
Our integrated stepper motors are stepper motors in which the motor, driver and controller are combined in a single housing. This design has several advantages:
- Compact design: As all the main components are housed in one casing, the entire structure is more compact and requires less space.
- Easy installation: The integration of the components eliminates the need to install and wire separate drivers and controllers, simplifying and speeding up installation and setup.
- Less cabling: Less cabling means higher reliability and less susceptibility to errors. It also reduces the electromagnetic interference (EMI) that can be caused by long cable runs.
- Built-in intelligence: Advanced functions such as microstepping, torque control, speed control and fault diagnostics are integrated.
- Cost savings: Integration can also reduce overall costs as fewer separate components need to be purchased and assembled.
- Simplified maintenance: With fewer separate components, maintenance is often easier as there are fewer potential sources of faults and problems can be diagnosed more quickly.
Typical applications for stepper motors with integrated control
Integrated stepper motors are used in a variety of areas, including
Automation technology: In machines and production systems where precise motion control is required.
Medical devices: In systems that require precise positioning and control, such as medication dosing.
Integration into the higher-level control system can be easily achieved with the available interfaces such as CANopen, Profi-Bus, Profinet or Ethercat.
Overall, integrated stepper motors offer an effective solution for applications where space, efficiency and ease of installation are important.

What are stepper motors?
Stepper motors are the preferred choice when it comes to the right drive for demanding positioning tasks. These electromechanical motors rotate in precise "steps", unlike conventional motors that perform a continuous rotary motion. This characteristic makes stepper motors ideal for applications that require precise positioning. A stepper motor with control is particularly indispensable when high accuracy is required. The design of these special drives ensures simple and precise operation, which is why they are widely used in automation technology. The stepper motor controller used, as used by Gunda Automation, is decisive for their reliability and precision.
Possible applications for stepper motors
Stepper motors are versatile drive systems that can be used in many areas. Their precise control and ease of use make them a popular choice for engineers and manufacturers. Here are some applications of stepper motors:
CNC machines: stepper motors are often used in CNC machines to perform precise positioning tasks in machine tools such as milling machines, lathes and laser engravers. Their high resolution and repeat accuracy ensure high-quality machining results.
3D printers: To ensure that print heads and print platforms move precisely, most manufacturers have their 3D printers controlled by a stepper motor. They enable the layer-by-layer production of objects with high precision.
Medical technology: Stepper motors are used in medical devices such as CT scanners, dialysis machines and insulin pumps to ensure precise movements and dosages, which improves the safety and efficiency of these devices.
Automation technology: Stepper motors with gears play an important role in automation technology, where they are used in conveyor belts, pick-and-place machines and packaging systems to transport and position products.
Textile machinery: In the textile industry, stepper motors are used in weaving machines, spinning machines and knitting machines to enable precise movements for the production of textiles.
Aerospace: Stepper motors are also used in aerospace technology, for example in the positioning of antennas and sensors as well as in the control of satellite movements.
Due to their versatility and precision, stepper motors are the preferred drive solution for many industries and applications that require reliable and high-precision motion control.
Advantages and disadvantages of stepper motors
Stepper motors are widely used in automation and offer various advantages and disadvantages that should be considered when choosing the right drive system.
Advantages of stepper motors:
Precision: stepper motors are known for their precise positioning, making them ideal for applications that require accurate control, such as in 3D printers or CNC machines.
Ease of control: Compared to other motor types, stepper motors do not require feedback on their position, which simplifies their control and reduces costs.
Torque at low speeds: Stepper motors offer high torque at low speeds, making them particularly suitable for applications that require precise movement at slow speeds.
No slippage : Unlike brushless motors, stepper motors have no slippage, which means they are better suited to certain applications where absolute positioning is required.
Disadvantages of stepper motors:
Resonance and vibration: Stepper motors are susceptible to resonance and vibration, especially at higher speeds: However, modern stepper motor controllers can significantly reduce this behavior.
Power consumption: Stepper motors can have a higher power consumption compared to other motor types, especially if they are operated without a closed loop, but this issue can also be solved with modern controllers.
Complexity at high speeds: At high speeds, stepper motors lose torque,this can lead to difficulties when used in applications that require fast movements.
Overall, stepper motors offer a precise and cost-effective solution for many applications. However, it is important to consider both their advantages and disadvantages to ensure they are suitable for the specific application. Gunda Automation relies on high-quality stepper motors and customized control solutions to maximize efficiency and precision in various industries.
