Two Speed 1.5 HP And 0.25 HP Electric Motor 115 Volt 3600 And 1800 RPM 48Y Frame Threaded Shaft Auto Overload Protector

Meet a compact, purpose-built dual-speed motor designed for versatile performance in single-phase 115V systems. With 3600 RPM at high speed and 1800 RPM at low speed, this 48Y frame motor delivers rapid, high-torque capability when you need it and smooth, controlled operation for precision tasks—all without swapping gearboxes or motors.

• Two-speed performance: 3600 RPM at high speed (up to 1.5 HP) for fast cycles and rapid material processing; 1800 RPM at low speed (up to 0.25 HP) for torque-heavy tasks and fine control.
• Single-phase 115V, 60 Hz operation with practical amperage: Full Load Amps 16.4 A at high speed and 4.4 A at low speed.
• 48Y frame with a threaded shaft for straightforward mounting and secure coupling to pulleys, gears, or belts.
• Auto overload protector (Type C) for built-in protection against overheating and overloads, helping extend motor life during demanding runs.
• Compact dimensions with an overall footprint of 12.83 inches, designed to fit into tight spaces on machinery, conveyors, pumps, and other equipment.

This motor shines in setups where variability is key. Ideal for equipment that requires both high-speed duty cycles and slower, torque-centric operations without the complexity of swapping motors. Use cases include conveyors, fans, pumps, small lathes or mills, and woodworking machines where a single, reliable two-speed solution simplifies wiring and maintenance.

Why choose this dual-speed motor over a single-speed alternative? It consolidates two performance profiles into one unit, reducing inventory, installation time, and setup adjustments. The 48Y frame ensures compatibility with a broad ecosystem of couplings and mounting brackets, while the threaded shaft makes attachment quick and secure. The auto overload protector adds a layer of safety, so you can focus on the job rather than on constant monitoring.

Practical setup tips: ensure your drive system is powered by a 115V, 60 Hz supply, select pulley sizes to match your desired speed ranges, and verify that your load aligns with the corresponding horsepower at each speed. Monitor current draw (16.4 A high speed, 4.4 A low speed) to confirm proper wiring and avoid overloads during peak operation.

This motor’s combination of dual-speed capability, protective features, and compact frame makes it a thoughtful, future-proof choice for workshop, shop floor, or small production environments where flexibility and reliability matter.
