Low-Profile, Direct-Drive Motion for Heavy-Duty Applications The ALAR family of direct-drive, large-aperture rotary stages provides superior angular positioning and velocity control. ALAR-LP (low profile) offers a generous payload capacity with a short overall height, making it ideal for space-constrained applications. Featuring a large-diameter clear aperture and a non-cogging direct- drive motor, ALAR-LP stages offer a better-performing alternative to worm-gear stages. Key Applications ALAR-LP stages are best suited for applications including: Single- and multi-axis sensor testing Inertial navigation device qualification Missile seeker testing Antenna testing Photonic component alignment High-accuracy laser processing Precision wafer inspection Custom gimbal assemblies KEY FEATURES: Large Aperture Rotary Stage ALAR-LP Offers a LOW-PROFILE FORM FACTOR with overall stage height as short as 65 mm for space- constrained applications INTEGRATES EASILY INTO SYSTEMS & MACHINES thanks to large-diameter clear aperture up to 325 mm Delivers EXTREMELY PRECISE, smooth, cog- free rotation with direct-drive torque motor SUPPORTS LARGE AXIAL & RADIAL LOADS, ideal for linear/rotary stage combinations & gimbal configurations Provides long service life & CONSISTENT PERFORMANCE over time Available with absolute encoder option & limited travel for MAXIMUM PAYLOAD SECURITY

Resolution assumes 1 Vpp encoder with 2000x controller multiplication. 2. Certified with each stage. Requires the use of an Aerotech controller. 3. Repeatability and accuracy are dependent on encoder selection. To achieve the listed specifications, the electrical resolution should be 0.2 arc sec or smaller. 4. Square-wave digital encoder options will limit maximum speed below the listed value. Contact factory for specific stage and encoder speed combination. 5. The ALAR-LP base must be fully supported by a rigid mounting surface to achieve the specified moment load.

The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system. -TAS Integration - Test as system Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration. -TAC Integration - Test as components Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
