Direct-Drive Lift Stage OMZS Series
Three-phase synchronous coreless linear motor drive for smooth motion.; Precision cross-roller guides effectively ensure motion accuracy and straightness.; Non-contact linear encoder with nanometer resolution for precise position feedback.; Unique assembly process requirements ensure product consistency.
Product Introduction
The OMZS direct-drive lift stage uses a three-phase synchronous coreless linear motor as the drive element, eliminating the mechanical parts in the power transmission system and transmitting drive force directly to the motion platform without friction for high speed and high acceleration. A coreless motor is ideal for positioning tasks with extremely high precision requirements, running smoothly even at very low speed with no vibration at high speed. A non-contact, ultra-high-precision optical encoder measures the platform position directly.
