Description
Ct1102 48Y Frame Motor 1 Hp Dual Voltage
From Century by A.O. Smith, the CT1102 is a compact, dependable 1 HP pool and spa motor designed to power a wide range of equipment with steady, efficient performance. Its dual‑voltage capability and robust 56J frame make it a practical replacement for pool pumps, spa pumps, and other belt‑driven loads in residential and light commercial environments.
- HP & RPM: 1 HP at 3450 RPM (two‑pole, 60 Hz) delivering solid starting torque for light‑to‑moderate loads.
- Voltage: Dual‑voltage operation for 115V or 230V supply, simplifying replacements in facilities with mixed power sources.
- Frame & Shaft: 56J frame with a threaded shaft for secure pulley or coupling attachment; 5/8" shaft diameter fits common fittings.
- Service Factor: 1.4 service factor provides margin for startup surges and brief overloads without overheating.
- Footprint & Fit: Compact, two‑compartment, open‑drip‑proof (ODP) enclosure footprint designed to fit a wide range of OEM and retrofit installations; roughly 12-1/8" effective length (AG) with a 23" connection diameter.
The CT1102 is designed for reliability in pool and spa environments, offering straightforward replacement with a familiar 56J frame and threaded shaft. Its dual‑voltage capability reduces wiring complexity and downtime when upgrading equipment or matching available power supplies. The 1.4 SF margin supports brief overloads and startup bursts common in pump and blower applications, while the open‑drip‑proof (ODP) design helps protect internal components in typical pool installations. For OEMs and retrofit projects alike, this motor delivers consistent performance and easy integration with pulleys, belts, or couplings.
Produced under the trusted Century Electric brand (A.O. Smith lineage), this motor embodies the durability and field‑tested engineering pool and spa professionals rely on for years. Its proven compatibility with 56J frame configurations and dual‑voltage operation makes it a dependable choice for replacing aging pool and spa drives or upgrading to a more versatile, easy‑to‑wire solution.

The 3450 RPM, two-pole profile delivers solid starting torque and brisk running speed for lightweight to moderate-load applications, while the 1.4 service factor provides a welcome margin for startup surges and brief overloads.
Robust, install-ready design
With a 56J frame footprint, this motor fits many OEM and retrofit setups without extensive rework. The threaded shaft simplifies pulley or coupling installation, and the connection diameter 23 accommodates common mounting and wiring configurations. The CT1102 is built for continuous operation in challenging environments, delivering consistent performance over time.
Ideal use cases
Best suited for:
- HVAC equipment such as air handlers and blowers
- Small to mid-size pumps
- Conveyor and material-handling drives
- General purpose belt-driven machinery requiring a compact 56J frame
Practical installation and optimization tips
- Ensure wiring is configured for the correct voltage (115V or 230V) to match your power supply and target load.
- Pair the threaded shaft with a properly sized pulley or coupling to maintain alignment and minimize vibration.
- Verify the mounting footprint aligns with your existing 56J frame setup to avoid rework.
- Leverage the Service Factor of 1.4 by planning for brief startup surges and occasional overloads without overheating.
- Consult the notes (1, 2) on the datasheet for any application-specific considerations or installation caveats.
Designed for reliability and versatility, the Motor 48Y Frame CT1102 is a practical, long-term solution for a wide range of industrial drives. Its combination of dual-voltage operation, solid frame compatibility, and secure shaft integration makes it a smart replacement or upgrade choice for compatible equipment.
