PSC Motors 2-16 Watts Output

The EM&S 4-pole permanent split capacitor unit bearing fan motors offer up to 47% efficiency, a nominal 50% increase in efficiency over shaded pole motors of similar physical dimensions and power output.  When looking for some energy savings, these are a less expensive alternative to the ECM motors.  The S4B motors are available in outputs of 2, 5, 6, 9, 12, and 16 watts output, 115 volts.

Energy savings in electrical motors offer the advantage of lower operating temperatures.  Heat is the great threat to extended motor life, as it promotes the viscosity breakdown of the lubricants, and reduces the effective life of the electrical insulation system.  So not only are these motors less costly to operate, but they are resistant to thermal breakdown, thus extending their service life.
