Powerful, dependable, and flexible—the B234 AOS motor is a compact dual‑speed solution designed to power a wide range of machines with precision. Built around a 56J‑frame and configured for thru‑bolt mounting, this 3.0 HP motor delivers both speed and control when you need it most.
-
Two‑speed performance: 3450 RPM on high gear and 1725 RPM on low gear, both at 230V. Perfect for equipment that requires a fast, belt‑driven start or a slower, controlled run for delicate operations.
-
Electrical efficiency and draw: Service factor 1.00 with current draw of 10A at high speed and 3.5A at low speed, enabling predictable electrical planning and safe, steady operation.
-
Secure, versatile mounting: Through‑bolt design for solid mounting and easy alignment in tight spaces, helping reduce vibration and extend service life.
-
Compact frame, ready to pair: 56J frame with a threaded shaft for straightforward coupling to belts, pulleys, or gears; keeps your layout clean and reliable.
-
Precise connection details: Shaft is threaded; Conn. Dia. 23 and approx. AG 11‑9/16 provide clear guidance for compatible couplings and mounting hardware.
This motor is ideal for applications where you need rapid acceleration with the option to slow down for accuracy and finish quality. Think small to mid‑sized conveyors, fans, pumps, lathes, drill presses, and light milling setups where a single motor can adapt to multiple operating modes without swapping equipment.
Use cases and setup advantages:
- Conveyors and material handling lines that require both high‑speed transfer and controlled low‑speed transfer for gentle handling.
- Woodworking or metalworking machines where you benefit from a fast startup and a precise, slower finishing speed.
- HVAC or airflow equipment needing versatile drive options within a compact footprint.
- Small pumps or auxiliary machines that benefit from a robust, through‑bolt mounted motor for reliable alignment.
