Description
1 HP Dual-Voltage Electric Motor for Pool & Spa Equipment — 3450 RPM, 56C Frame
From the trusted A.O. Smith (AOS) / Century Electrical lineage, this 1 HP single-phase motor delivers dependable, steady performance for pool and spa equipment. Its compact 56C frame and dual-voltage design make it a practical upgrade for pumps, fans, and light-to-medium-load drives in tight spaces.
- Power and speed: 1 HP rated, 3450 RPM for reliable, consistent drive of pool pumps, spa circulators, and related equipment.
- Voltage: Dual-voltage operation (115V / 230V) to match existing electrical setups and simplify replacements in mixed environments.
- Service Factor: 1.4 SF provides extra headroom for brief overloads and startup surges, helping maintain performance during peak demand.
- Frame: 56C frame offers broad mounting compatibility with standard brackets, couplings, and adapters.
- Shaft: Keyed shaft ensures precise coupling alignment and reduces wear on driven components.
- Current draw: Approximately 13.6 A at 115V or 6.8 A at 230V, aiding accurate electrical planning and protection sizing for pool/spa installations.
- Durability: Robust industrial construction designed for reliable operation in wet, humid pool and spa environments with routine maintenance.
- Ideal uses: Pumps, fans, blowers, and light-to-medium-load conveyors in compact systems; excellent for retrofits and new installs needing a standard 56C, keyed-shaft motor with dual-voltage capability.
Designed to simplify installation and extend service life, this motor provides space-efficient, dependable 1 HP power for pool and spa equipment. The dual-voltage capability minimizes wiring constraints and spare parts, while the 1.4 service factor cushions startup surges common in circulating and filtration systems. The keyed shaft ensures secure coupling alignment and reduces wear over time, supporting longer bearing life and smoother operation. For best results, wire to the selected voltage with appropriate overload protection, mount with compatible 56C hardware, align belts or couplings carefully to minimize vibration, and keep the shaft area clean and well-maintained to maximize longevity.
Meet the versatile 1 HP motor built to power your small- to mid-size equipment with dependable, steady performance. With a dual-voltage design and a compact 56C frame, this motor balances power, flexibility, and space—a smart upgrade for pumps, conveyors, fans, and other light- to medium-load machines.
