56 Frame Electric Motors
(1) Look for the label provided by the original electric motor manufacturer (see Figure 2). Manufacturers include “Century”, “Magnetek”, “A.O.Smith”, “Regal Beloit”, “Emerson”, “Franklin Electric”, “GE”, “Centurion”, “SNTech”, “Dynatech”.
(2) Identify the voltage required (115 volts or 230 volts), “high” and “low” speeds (spa pump motors are typically 3450 RPM high speed and 1725 RPM low speed). Single speed motors are “high” speed (3450 RPM). Circulating pump motors are “low” speed (1750 RPM).
(3) Identify the amperage and ALWAYS choose a replacement motor with the same or higher amperage on high speed.
Example: Figure 2 shows an “A.O.Smith” label indicating 230 Volts and 12.0 Amps High Speed (Amps are 12.0/4.4 indicating 12.0 high and 4.4 low).
NOTE: All the motors below are identified by original motor manufacturer catalogue number. Catalogue numbers are issued by the motor companies to be used by distributors. Motor manufacturers assign EMI numbers (also known as part numbers) to pump manufacturers to distinguish between distributors and pump manufacturers, however both motors are the same.
