H2W Technologies debuts new linear stepper motor positioning stages

September 27, 2018 – H2W Technologies has released a new series of low-profile linear stepper motor positioning stages that integrate an absolute linear encoder and a single-axis linear stepper motor stage.
LSS-016-04-006-01A-ME enables the linear stepper motor stage to operate as a two-phase brushless linear motor when coupled with H2W motion control electronics, which allows the stage to achieve speeds, accelerations and accuracies previously unachievable with a standard open-loop linear stepper motor.
When operated this way, the motor tends to run cooler as it only draws current when needed to hold the desired position or make a move. Using absolute encoders removes the need to use home position sensors as the absolute position of the system will always be known, even after power is cycled, and end-of-travel limit switches provide protections against over-travel situations.
The stages use H2W’s STS-0620-R linear stepper motors to generate a force of 6 lbs [26.7 N] with a total stroke length of 406 mm (16 in) and the 1.0-micron resolution absolute encoder allows for precise positioning. High flex power cables for the motor and encoder are guided by a cable carrier and the cables are terminated into standard D-subminiature connectors. There is also a provision for customer cables to be routed within the cable carrier. Custom mounting holes on the moving table and base are available upon request at no additional charge.
