Superior Electric synchronous motors are high pole count<br />
motors that naturally turn at slower speeds (72 or 60 rpm).<br />
They only need a resistor – capacitor (RC) network to operate from<br />
single-phase AC utility power. For loads that operate at 72 RPM or<br />
slower, they are very cost effective and simple to use.<br />
Other motor technologies (induction, DC, servo and step motors)<br />
either need gear reducers, or electronic drives to match the speed of<br />
Superior Electric synchronous motors. The cost of just the gear<br />
reduction or the cost of the electronic drive will usually exceed the<br />
total cost of the Superior Electric synchronous motor.<br />
For even slower speeds planetary gear reducers are offered.<br />
Superior Electric synchronous motors produce very<br />
low speeds with only modest gear reductions.<br />
