ST/SN Series AC Synchronous Motors
ST and SN Series synchronous motors provide high performance in three frame sizes, NEMA 23, 34 and 42 (60, 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.
Limited availability outside North America
