Kollmorgen SN3/SN4 Series AC Synchronous Motors

SN3/SN4 Series AC Synchronous Motors provide high performance

in two frame sizes, NEMA 34 and 42 (90 and 110 mm).

Resistor-capacitor kits are also available. These motors are driven

economically from standard AC line voltage and the synchronous

speed is related to the line frequency.
