BURLINGTON, MA — Steinmeyer, Inc. announced a new low profile, high precision, linear stage model LT190-EDLM.
Manufactured from high strength aluminum, the table is driven by an ironless core linear motor with travel ranging from 150 mm to 500 mm. Total table height is only 50 mm. Positioning accuracy, repeatability and maximum speed depend on which one of three high precision encoders is included. Typical speed is 1 m/sec with acceleration of several G’s. The stage is designed so that two units may be mounted together directly without an additional interface plate creating a low profile XY configuration (see photo). Together with a rugged right angle bracket, a three axis XYZ arrangement is also available. Features of this new table include:
• preloaded large cross roller bearings for high stiffness and smooth motion
• cage assist mechanism to prevent cage migration and ensure reliable operation under high
accelerations and speeds of the linear motor drive
• sealed design using metal way cover instead of accordion type bellows, eliminating particle
generation
The LT190-EDLM offers three linear scale options based on the customer’s resolution requirement, from standard 20 nanometers to 6.25 picometers.
