In the transition toward electric vehicles, servomotors offer significant advantages over pneumatic cylinders in terms of precision, efficiency, response speed, torque capacity, versatility, and durability, among others.
With this post, we aim to highlight the major solutions that can be achieved by implementing small changes in production lines, using such a common element in automation engineering as servomotors.
Vehicle manufacturers are increasingly requiring flexible solutions to adapt existing facilities to the production of new electric car models, avoiding the investment that would be needed to install new lines and optimizing processes and space.” – Borja Marcos, mechanical designer at Gurpea-.
Flexibility and adaptability in engineering solutions translate into operational efficiency and optimization of production processes by leveraging existing infrastructures for the manufacturing of new body models.
Additionally, this flexibility provides companies the ability to make future adjustments based on market needs and emerging technological innovations, ensuring an agile response to changes in demand and regulations.
- Bivalence project: combustion and electric.
An example of this is the project to adapt the cockpit manipulator to electric vehicle production, whose objective was to achieve bivalence in the production of combustion and electric vehicles on the same line and process, using the same resources.
The inclusion of four servomotors—1 in the octopus clamp and 3 in the cockpit gripper—allows width and height adjustments to adapt the grip, entry, and exit for four different body and dashboard models, offering much greater flexibility and precision than pneumatic cylinders.
- Advantages of Servomotors over Pneumatic Cylinders
Servomotors are common and essential devices in a variety of industrial and technological applications due to their numerous advantages:
- Precision and Control: Servomotors offer precise control of position, speed, and acceleration. This is achieved through a feedback system that continuously adjusts the motor’s position, making them ideal for applications requiring high accuracy, such as robotics and CNC machinery.
- High Efficiency: Servomotors are highly efficient at converting electrical energy into mechanical motion. This not only reduces operating costs but also minimizes heat generation, extending the motor’s lifespan and that of associated components.
- Fast Response: Thanks to their rapid response capabilities, servomotors can quickly reach the desired speed and adjust their position almost instantly. This feature is crucial in dynamic applications where rapid changes in direction and speed are common.
- Torque Capacity: Servomotors provide high torque across a wide range of speeds, making them suitable for tasks that require considerable force during starts and stops. This capability facilitates handling heavy loads with greater ease and stability.
- Compatibility and Versatility: Servomotors can be easily integrated with various control systems and are compatible with a wide range of controllers and software. This versatility enables their use across multiple industries, from automotive to industrial process automation.
- Durability and Reduced Maintenance: Servomotors are designed to be robust and durable, requiring minimal maintenance. Their sealed design protects internal components from dust and other contaminants, ensuring reliable and long-lasting performance.
- Noise and Vibration Reduction: Compared to other types of motors, servomotors operate with significantly lower levels of noise and vibration. This not only improves the working environment but also reduces mechanical wear, contributing to longer system lifespan.

- Conclusion
Servomotors represent an advanced and efficient solution for a wide range of applications thanks to their advantages in terms of precision, efficiency, response speed, torque capacity, versatility, durability, and low noise levels. These characteristics make them an essential component for the automation and improvement of modern industrial processes.
Although both servomotors and pneumatic cylinders have their own advantages and disadvantages, servomotors stand out in applications requiring high precision, efficiency, rapid response, and versatility. Meanwhile, pneumatic cylinders are more suitable for simple linear movements requiring high force, although they may be less efficient and require more maintenance. The choice between one or the other depends on the specific needs of the application.
