High precision Linear motors now with force feedback

Linear motors are ideal for fast and accurate motion in a machine .
Linmot , the leading manufacturer of cylindrical linear motors , has made them even more suitable for demanding products that require exceptional cleanliness in the production environment . This has always been demanding for machine designers , but has been made much easier by using the Linmot DM01 Linear motor modules .
The DM01 Linear modules provide high precision positioning while supporting high loading with the following features :
• Stroke up to 575mm and peak force up to 572N
• Direct load mounting up to 30kg
• Clean Design
• No Slider lubrication is required .
• Higher stiffness / lower bending
• Load balance ( MagSpring ) & pneumatic holding brake option
• Can be combined to form two-axis systems
• Are available certified for Clean Room Applications .
INCREDIBLY SENSITIVE FORCE CONTROL
The latest option that has just become available is the addition of a force sensor combined with force control software .
This is an option that can be added to any of the DM01 modules .
Just to demonstrate how sensitive , you can place an egg between two DM01 modules , one equipped with the new Force sensor .
One DM01 module moves with a programmed movement while the other follows while maintaining a precise 5 N force at all times to hold the egg without breaking it as shown in the picture .
A video of this application is available on our website ( see below ).
Using a regular force sensor requires precision alignment or measurement error will occur .
Linmot ’ s special design provides excellent measurement accuracy even with axially offset loads or with side loading from an attached load ( such as a gripper for example ).
Here is a section through the sensor to show how the load is guided combined with the special design of the sensor itself .
While handling such delicate tasks , it can also handle up to +/ - 500N of force combined with an accuracy of 1 %.
This exciting new option opens up many new applications and makes the Linmot DM01 a unique and powerful new tool for the machine designer who needs sensitivity as well as force and dynamic speed .
