Direct-Drive Motorized Stage EPSW Series
Efficient three-phase iron-core synchronous linear motor drive for higher loads.; Precision linear slide-guide ensures motion accuracy and straightness.; Non-contact linear encoder with nanometer resolution.; Unique assembly process requirements ensure product consistency.
Product Introduction
The EPSW direct-drive motorized stage is a semi-sealed design. An efficient three-phase iron-core synchronous linear motor is used as the drive element, giving a shorter profile than screw-driven stages for a more compact, space-saving solution — ideal for space-constrained applications needing high throughput, high reliability and ultra-quiet operation. Precision-grade self-aligning ball linear guides ensure high running straightness and parallelism. A non-contact linear encoder provides nanometer resolution with excellent position sensitivity, reliable repeatability and stability. The main body uses lightweight, high-strength aluminum alloy.
