The LSS-016-04-006-01A-ME is one of a revolutionary new series of low-profile linear stepper motor positioning stages that integrates an absolute linear encoder and a single-axis linear stepper motor stage. This enables the linear stepper motor stage to operate as a 2-phase brushless linear motor when coupled with motion control electronics provided by H2W Technologies (H2W).
Operating as a brushless linear motor 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 since it only draws current when needed to hold the desired position or make a move. Using absolute encoders eliminates the need to use home position sensors since 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 motor to generate a force of 6.0 lbs [26.7 N] with a total stroke length of 16 in. [406 mm], 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.
