Regal Rexnord st1102 Pool Pump Motor 1 Hp 56J

Product Description

The REGAL REXNORD st1102 is a single-phase pool pump motor rated at 1 HP and 3450 RPM, built for continuous-duty operation in residential and light commercial pool pump applications. It runs on dual-voltage input of 230 or 115 volts AC at 60 Hz, giving installers flexibility when wiring to existing circuits. The motor features an open drip-proof enclosure, a 56J frame with round mounting, and a 5/8-inch shaft with counter-clockwise rotation at the pump end. Ball bearings, a 1.5 service factor, and Class B insulation make this a dependable drop-in replacement for standard pool pump motors.

This motor is designed for single-speed pool and spa pump systems where a 56J frame, 5/8-inch shaft, and counter-clockwise pump-end rotation are required. It suits residential above-ground and in-ground pool pump assemblies and is a common replacement for worn or failed OEM motors in seasonal and year-round pool service environments. Pool service technicians and licensed electricians typically encounter this frame and voltage configuration across a wide range of pump brands and housings.
