The Parker mSR Series is a compact linear motor stage designed for instrument builders and precision OEM applications. Featuring both ironless and ironcore linear motors with high-resolution encoders, it delivers ultra-smooth motion with sub-micron accuracy which is ideal for cleanroom environments and embedded applications.
The Parker XLM Series are ironless linear motors building for machinery or instrument builders who need smooth motion and high precision. 
The Parker ZFA Series is a voicecoil actuator designed to achieve nanometer level stability in milliseconds for ultra-high precision vision applications in life sciences, semiconductor and metrology applications. 
DISCONTINUED! The Parker 400LXR Series provides highly smooth performance through slotless motor technology which minimizes current ripple in the phase transitions. Look at the mSR and XLM series for new designs. Expert Advice
For applications requiring linear motion, there are various types of linear mechanics that can be applied. The three most typical types to compare are ballscrew actuators vs belt & pulleys vs linear motors. There are even various types of linear motors as explained in Episode 42 of The Motion Control Show:
Some series of precision linear motion control stages employ different technologies for different sizes to take advantage of the various benefits for different applications.
Key Considerations in Choosing Linear Servo Motor Positioners
- Precision & Speed: Linear servo motor positioners are great for high-precision applications that demand both precision and speed in the same motion application. They are a primary technology for sub-micron positioning systems, especially ones needing high acceleration rates.
- Vertical Limitations: They are usually avoided in vertical applications, but there are various methods that can be employed for them.
- In-House vs Pre-Engineered solutions: OEMs and machine builders often find themselves asking the question of whether they should design their own actuators from the coil and magnet track up or should they use pre-designed actuators. There are lot of factors to consider when debating between in-house designs versus pre-engineered solutions.
- Linear Servo Motors: Linear servo motors are the core technology used in linear servo motor actuators. There are different types of linear servo motors to be aware of: iron core and ironless are the two primary types.
- Linear Encoders: Linear servo motor actuators rely on linear encoders to function which do have their own errors and inaccuracies to consider and understand.
