AC SloSyn

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. Other motor technologies (induction, DC, servo and step motors) either need gear reducers, or electronic drives to match the speed of Superior Electric synchronous motors. The cost of just the gear reduction or the cost of the electronic drive will usually exceed the total cost of the Superior Electric synchronous motor. For even slower speeds planetary gear reducers are offered. Superior Electric synchronous motors produce very low speeds with only modest gear reductions. 

• 72 rpm motor speed (with 60 Hz voltage)
• 60 rpm motor speed (with 50 Hz voltage)
• Constant speed does not vary with the load
• 120 volt or 240 volt AC models
• Torques: 70 to 1,500 oz-in (50-1,069 N-cm)
• Gear reducers with ratios up to 125:1 and torques up to 5,000 oz-in (3,670 N-cm)
• UL and CE hazardous duty versions
• Fast starting, stopping, or reversing
• Can be stalled indefinitely without overheating
