Synchronous Motors
Pacific Scientific Synchronous Motors
ST/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.
- ST models, NEMA 23 (60 mm) motors: three stack length options with torque ratings to 131 N-cm (185 oz-in).
- SN3 models, NEMA 34 (90 mm) motors are available in three stack lengths with torque ratings from 198 to 636 N-cm (280 to 900 oz-in).
- SN4 models, NEMA 42 (110 mm) motors are available in three stack lengths with torque ratings from 500 to 1060 N-m (715 to 1500 oz-in).
- All models offer flying lead, terminal box, connector and shaft extension options
Superior Electric Synchronous Motors
Superior Electric synchronous motors are high pole count motors that naturally turn at slower speeds (72 or 60 rpm). They only need a resistor – capacitor (RC) network to operate from single-phase AC utility power. For loads that operate at 72 RPM or slower, they are very cost effective and simple to use.
- KS06, KS09, KS11 Series - High Torque - NEMA 23, 34 42
- SS240, SS450 Series – NEMA Size 34
- Hazardous Duty Motors – NEMA Sizes 42, 66
