Linear Motor Stage EPSZ Series
Three-phase coreless linear motor direct drive.; Precision cross-roller guides effectively ensure motion accuracy and straightness.; Non-contact linear encoder with nanometer resolution.; Unique assembly process requirements ensure product consistency.
Product Introduction
The linear motor used in the EPSZ linear motor stage is an electromagnetic direct drive. Such motors eliminate the mechanical parts in the power transmission system and transmit drive force directly to the motion platform without friction, enabling high speed and high acceleration. A coreless motor is ideal for positioning tasks with extremely high precision requirements, since it does not interact adversely with permanent magnets; it runs smoothly even at very low speed and produces no vibration at high speed, avoiding non-linear control behavior with easy control at every position. A non-contact, ultra-high-precision optical encoder measures the platform position directly.
