• Linear brushless servomotor and noncontact encoder eliminate typical ball screw or belt maintenance
• Force outputs from 32 N to 276 N
• Counterbalance is available for vertical applications
Faster than a ball screw, more accurate than a belt drive, the LMA and LMAC series actuators harness the speed, acceleration, and accuracy capability of a linear motor for the latest in high-throughput linear actuator technology. This modular stage is ideal for pick-and-place machines, gantry axes, shuttle stages, assembly machines, or as a general-purpose positioner.
Since the LMA and LMAC series actuators integrate the mechanical and electrical components, they eliminate the guesswork involved in choosing bearings, motors, encoders, and the other components required for a linear motor system.
High Speed, High Acceleration
With a no-load acceleration of 5 g and a top speed of 5 m/s, the LMA and LMAC series actuators are the ideal solution to increasing throughput. A high-power brushless linear servomotor drives the LMA and LMAC actuators to speeds and resolutions that are impossible with a ball screw.
Excellent Accuracy and Repeatability
The feedback device is a directly coupled, high-accuracy linear encoder. Since the encoder is mounted in close proximity to the work surface, accuracy problems associated with pitch, roll, and yaw are greatly reduced. Repeatability is ±0.5 µm over the length of travel. The linear encoder is a robust, noncontacting scale with resolution options ranging from 0.1 µm to 1.0 µm.
OEM Version for
Application Flexibility
For applications requiring integration into a custom machine, an OEM version is available. The OEM version offers all of the same performance characteristics as the standard actuator, but allows the user to eliminate or modify different characteristics of the actuator. For example, the user can provide their own cable management system, choose a different bearing system, or customize the mounting holes.
High Reliability
The LMA/LMAC linear motor drive system consists of two noncontacting parts, making the actuators virtually maintenance-free. As a result, there is no backlash, windup, wear, or maintenance that is normally associated with contacting-type systems such as ball screws or belts.
