Description
Meet the Motor, 2×1/3 HP, 48Y Frame—a compact, dual‑speed solution designed to power a wide range of machines with fewer components and simpler wiring. With two 1/3 HP windings, this unit delivers two distinct speeds from a single motor: 3450 RPM at high speed for rapid acceleration, and 1725 RPM at low speed for heavier loads and improved torque control, all fed by a 230 V supply.

Why this dual‑speed design matters
This motor delivers real value where load conditions vary. In high‑speed mode, you get quick starts and fast belt or driven tool engagement. When a task demands more torque or steady, controlled operation, switching to the low‑speed setting keeps harnessed power under control without swapping gears or motors. The 48Y frame ensures broad compatibility with common mounting footprints, making retrofits and new builds straightforward.
Ideal use cases
- General machinery and conveyors that need two operating speeds to handle startup and full‑load tasks
- Small fans and pumps where torque at reduced speed optimizes performance and energy use
- Machine tools and packaging equipment requiring flexible drive options without additional hardware
- Retrofits in existing systems where a single motor can replace two, reducing inventory and maintenance
Practical notes for installation and operation
Plan for a 230 V supply and verify wiring can accommodate the dual‑speed control. With a service factor of 1.1, this motor provides a comfortable margin for temporary overloads, helping to protect against unexpected surges. Use correct pulley sizing and alignment to maximize the benefits of the two speeds, and reference the listed conduit and mounting dimensions to ensure a clean, reliable fit in your enclosure.
