General Purpose Motor 1/2 hp 48 Frame

The Dayton 103805.00 is a capacitor-start/run motor rated at 1/2 horsepower for continuous duty in general purpose applications. It operates on single-phase power at 60 Hz and fits a standard 48 frame mounting. The rigid base and open drip-proof enclosure suit indoor industrial environments where automatic thermal protection is required.

Dual Voltage 115/208-230V Operation

This motor runs on 115 volts or 208-230 volts AC, drawing 4.4 amps at the lower voltage and 2.4 to 2.2 amps at the higher voltages. It is also usable at 208 volts, providing flexibility for common North American supply voltages. The nameplate speed is 3,450 RPM with a service factor of 1.25 for occasional overload capacity.

Continuous Duty Thermal Performance

Automatic thermal protection resets after a trip, allowing uninterrupted operation in ambient temperatures up to 40 degrees Celsius. Class B insulation supports the continuous duty cycle at the rated service factor. The open drip-proof design promotes airflow for cooling while the motor weighs 20.85 units for stable rigid-base mounting.

Questions about this item

What does the 1/2 hp rating mean for actual workloads on this motor?

The motor delivers 1/2 horsepower continuously at a 1.25 service factor, so it can handle brief overloads above the rated load without tripping thermal protection.

How does the 115/208-230V dual-voltage design affect the current draw?

At 115 V the motor pulls 4.4 A full-load; at 208-230 V it draws 2.4-2.2 A, letting you match the supply voltage available in the shop.

Will the 48 frame and rigid base fit my existing mounting points?

The NEMA 48 frame with closed-base rigid mounting uses standard bolt patterns for that frame size, so it aligns with common 48-frame mounting holes.
