Although servomotor technology has been around for quite a long time now, many machines are still produced with often over-complex drivetrains. In addition, great potential can be found in upgrading older machinery to reduce maintenance cost and increase flexibility.
We challenge you to look at your situation and question if servomotor technology wouldn’t be the better choice?
Our automation experts provide you 6 thoughts to consider…
1. Lower wear and tear
Where mechanical drivetrains typically consist of a multitude of components working together that are subject to friction, servomotors are installed close to the point of use, significantly reducing the overall amount of wear and tear parts.
2. Higher accuracy over distance
As a drivetrain gets longer, the inaccuracies due to backlash add up. The further away from the motor, the less accurate the position control will be. The electronic link between servomotors is independent from distance and provides similar accuracy at each point of use.
3. Better motion control
Although frequency controlled asynchronous motors offer good possibilities to allow speed variations, the control range is limited to 20-60Hz. In contrast, servos offer greater flexibility with their possible speed range of 1-100%, which ultimately leads to smoother running production lines.
4. Energy efficiency
Servodrives can get their power from 1 linked DC-bus, resulting in a very efficient power management as one drive can provide its remainder in energy (eg during braking) to another, requiring extra energy (eg during acceleration). This way, the machine’s overall power consumption is limited and peak loads on the power grid are avoided.
5. Improved accessibility and ergonomics
As motors can be placed close to where the action is happening, a lot of free space is created in between. This offers great advantages in terms of accessibility, ergonomics and even hygienic design.
6. Combination of movements
Synchronizing a rotational and linear movement becomes a lot easier with servos. Where in the past often a crankshaft connection was used, today it can easily be solved by programming + use of linear servomotor. On top of this, the movements can even take place any direction without mechanical restriction.
