identify motors not specified by NEMA mounting
and shaft standards.
4. TYPE: The electrical design of the motor is shown
by its type. A.O. Smith uses “CX” to identify its
switchless design. Other codes include “CS” for
capacitor-start, “S P” for split-phase and “CP” for
capacitor start / capacitor run. Be sure to check with
the dealer or distributor, because motor type codes
may vary among manufacturers.
5. HP (Horsepower): Conventional unit of measure-
ment for power. One horsepower equals 746 watts.
6. RPM (Revolutions Per Minute): RPM states the
rotational speed of the shaft at rated load.
7. HZ (Hertz): Measurement of frequency, equaling
cycles per second of alternating current.
8. PH (Phase): Denotes a single- or three-phase
motor.
9. SF (Service Factor): Service factor is the measure
of the reserve margin built into a motor. Motors
rated over 1.0 SF allow the motor to operate at a
higher margin than designated by the horsepower
rating. Maximum horsepower capability equals
horsepower multiplied by the SF.
(continuous operation).
10. VOLTS: Voltage is the required electrical potential
applied to the motor, the force that produces current
in an electrical conductor.
11. AMPS: Electrical current flowing through the
conductors. On pool motors, the amperage is
maximum or service factor amps that result at
11
