Synchronous motors can be used in explosive situations

Superior Electric XCE series hazardous duty synchronous motors from Danaher Motion satisfy ATEX standards for use in potentially explosive atmospheres as defined by CE directive 94/9/EC. The motor’s flameproof enclosure makes it suitable for use in surface industries exposed to gases, including hydrogen and acetylene. Motors also are available in UL-listed versions for use in Class 1, Group D hazardous locations. The synchronous motors are high pole count motors that naturally turn at slower speeds (72 rpm with 60-Hz power, or 60 rpm with 50-Hz power). They only need a resistor-capacitor network to operate from single-phase AC utility power.
