Hiwin Air bearing stage - LMAP
ไฮวิน Air bearing stage - LMAP
Hiwin Air bearing stage - LMAP : Low profile, XY symmetric structure design, with high stiffness granite base magnetic preload designed to enhance stabillty, with excellent grometrical property; applies ironless linear motor, no cogging to parid setting time, that provides exellent smooth motion and positioning accuracy; strong beam desin uses high stiffness lightweight aluminum, reduces weight of moving unit; gantry dual-drive struture and use of two sets of optical linear encoder for feedback compensation, offers dynamic control and error mapping; for clean room, no lubrication for easy maintenance and provides high flexible cable management.

Note :
- The maximum resolution is up to 4096 times, resolution accuracy is about 4 nm
- Absolute accuracy is after error mapping.
- Required specification is restricted by load, this specification is based on empty load
- Must comply with the resolution of encoder and number of mass transfer rate
- Based on the limitations of motor instantly force, only allow moving unit mass about 8kg (center load)
- It is recommended to link pressure switch on the emergency stop devices to protect air bearing from overloading
- Free of load
