The AOS Motor 56FR 2.0 HP 2-speed 230V Through-Bolt motor is a compact, rugged solution built for spa and pool equipment as well as other belt-driven applications. Its 56J frame, threaded shaft, and rigid through-bolt mounting deliver reliable performance in tight spaces and demanding environments.
-
Two-speed operation: 3450 RPM at high speed and 1725 RPM at low speed, allowing you to tailor torque and speed to your application without swapping gearboxes or pulleys.
-
Voltage and current: 230V single-phase power with a current draw of 8.0 A (high) and 3.0 A (low) for efficient startup and running.
-
Frame and mounting: 56J frame offers a compact footprint without sacrificing strength; through-bolt mounting provides a rigid, vibration-resistant connection in busy environments.
-
Shaft and couplings: Threaded shaft simplifies coupling and alignment; standard connection diameter of 23 mm with approximate AG of 11-9/16 in ensures compatibility with common drive hardware.
-
Durability and brand assurance: Designed by A.O. Smith (Century Electrical) for long service life and dependable performance in pool, spa, and light industrial installations.
Ideal for spa pumps, pool equipment, conveyors, fans, pumps, and small machine tools where space is at a premium and reliable, two-speed performance matters. The 2.0 HP rating provides solid startup torque and steady running, while the through-bolt design and threaded shaft enable quick, vibration-free installation. For best results, pair with a compatible two-speed controller and ensure a clean 230V supply; match couplings to the 23 mm shaft and keep mounting surfaces flat to maintain precise alignment.
