STAR Motors & Alternators: 1S102M/A

The 1s102M/A is high efficiency, linear reciprocating device that can be used as a motor or alternator.

The shaft is supported by Qdrive's patented flexure design which provides a single degree of motion and eliminates contact between moving parts. This, by design, requires no maintenance and offers virtually infinite life. The 1s102M/A has a stroke limit of 12 mm and is driven by up to 125 Watts of AC power.
