STAR Motors & Alternators: 1S241M/A

The 1s241M/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 1s241M/A has a stroke limit of 24 mm and is driven by up to 2,000 Watts of AC power.
