Nidec-US Motors D1P2AH Motor

The Nidec U.S. Motors D1P2AH is a 1 HP general-purpose three-phase AC motor designed for commercial and industrial applications such as pumps, fans, blowers, compressors, conveyors, and other properly matched equipment. This 1 HP three-phase motor operates on 208-230/460 VAC, 60 Hz power and has a full-load speed of 1725 RPM.

The D1P2AH uses a NEMA 56H frame, rigid base mounting, and an Open Drip-Proof (ODP) enclosure intended for suitable clean and relatively dry operating environments. The motor also features reversible rotation and 6203 bearings.

For replacement applications, contractors and service technicians should verify the original motor nameplate and equipment requirements before installation. Horsepower alone does not determine compatibility. Voltage, phase, RPM, frame size, shaft dimensions, mounting configuration, rotation, enclosure type, and electrical characteristics should all match the application.

Common Questions

What voltage does the Nidec D1P2AH use?
The D1P2AH is a three-phase motor designed for 208-230/460 VAC at 60 Hz.

What is the horsepower and RPM?
The motor is rated at 1 HP with a full-load speed of 1725 RPM.

What are the amperage ratings?
Published specifications indicate approximately 3.2 A at 208V, 3.0 A at 230V, and 1.5 A at 460V under full-load conditions. The 3.8-3.6/1.8 A figures correspond to service-factor loading.

What frame size does the D1P2AH use?
The motor uses a NEMA 56H frame with rigid base mounting.

Is the motor rotation reversible?
Yes. The D1P2AH is designed with reversible rotation.

Can the D1P2AH be used outdoors?
The motor has an Open Drip-Proof (ODP) enclosure. The installation environment must be appropriate for an ODP motor and should not expose the motor to conditions requiring a totally enclosed design.

How do I confirm this motor is the correct replacement?
Check the original motor and equipment specifications for horsepower, voltage, phase, RPM, frame size, shaft dimensions, mounting, rotation, enclosure, and electrical characteristics before ordering.
