  • 670 lb overhung load capacity handles radial shaft forces reliably
  • Totally enclosed fan-cooled motor runs in any mounting orientation

Industrial AC Gearmotor for Fixed-Speed Drives

The Dayton 4CVU1 is a single-shaft right-angle gearmotor rated at 299 in-lb maximum torque and a 45 RPM nameplate speed. Its capacitor-start motor runs on 115/208-230V AC and is housed in a totally enclosed fan-cooled enclosure with Class B insulation. The 39:1 gear ratio suits conveyors, mixers, printing presses and pumps that need constant, reversible rotation.

Mounting Flexibility and Shaft Layout

The unit mounts at any angle with the output shaft positioned at a 2.5 in height on the left-hand side. Overhung load capacity reaches 670 lb, allowing direct coupling to pulleys or sprockets without additional bearing support. No brake is fitted, so the shaft coasts freely when power is removed.

Fixed Voltage and Speed Constraints

Operation is limited to the stated dual-voltage AC supply; no variable-frequency drive compatibility is indicated. The single nameplate speed of 45 RPM cannot be altered without changing the gear ratio or motor. Reversing requires external wiring to swap rotation between clockwise and counter-clockwise.

Questions about this item

How often will the gearbox oil need changing on this 39:1 gearmotor?

The unit is shipped ready to run with factory lubrication; Dayton does not publish a service interval for the gearbox in the supplied data.

What limits continuous duty on the 299 in-lb output?

The motor insulation is Class B, so winding temperature is the first constraint during sustained operation at full 299 in-lb load.

How hot and loud does the 45 RPM right-angle gearmotor get running all day?

The totally enclosed fan-cooled housing keeps surface temperature within Class B limits and fan noise is typical for a 115/208-230 V capacitor-start motor at 45 RPM.
