KS Series AC Synchronous Motor Reluctance Synchronous, Torque to 250 oz-in. at 1RPM:
KS Series

A direct replacement for other motors of this type, KS Series motors are available for both direct drive and geared applications. Direct drive models offer a 60Hz synchronous speed of 1800 RPM. Both direct drive and geared motors are reversible, designed for continuous operation and require no maintenance lubrication. Motors provide a NEMA type 2-11 mounting.

Geared models have a "Heli-Spur" combination with the primary gear stage helical and the subsequent stages, spur. This gearing design provides for quiet, efficient operation. Maximum gear train loading is 250 ounce-inches at 1 RPM. Motors listed are 115 VAC at 60 Hz and require a capacitor.
