Precision linear motor stages
Kollmorgen’s MMG series of precision linear motor stages deliver lead times of two weeks or less facilitate reduced-time-to-market with a higher performing machine for OEMs, or provide greater machine uptime for end users in production environments. Four models are available that deliver 25mm, 50mm 100mm and 150mm travel, respectively. They provide uncompensated accuracy ranging from 6um to 14um and resolution ranging from 1.0um to 5nm.
Each model delivers repeatability to ±0.4um and is rated for 10kg load capacity. An integrated advanced feedback mechanism enables exceptional uncompensated accuracy. This encoder eliminates the need for compensation tables or slope correction factors, thus lowering software and integration complexity and implementation time.
MMG stages leverage a 3-phase brushless motor to enable control. No specialized piezo or proprietary motor/drive technology is necessary. MMG stages can be used in constant velocity (CV) or high throughput point-to-point applications, allowing common units to be used.
For OEMs, this lowers Bill-of-Material (BOM) costs while reducing and simplifying their unique parts count. Their precise performance, short lead times and lower cost of ownership make them useful for life science and clinical diagnostic instruments. They are also well suited for use in OEM Metrology applications and photonics/laser machining applications.
