Industrial Motor for Power Transmission

The Dayton 31TR84 is a general purpose motor rated at 2 HP and 1725 RPM for driving industrial machinery. It operates on 115/208-230V AC and carries a UL listing under file E47479. The 56HZ frame fits compressors, air tanks and pneumatic tools.

Suitable for Fixed Speed Applications

This motor suits installers who need a reliable, constant speed drive for pumps, fans or material handling equipment. It is not for buyers who want variable speed control because the unit is not rated for inverter use. The 84.5% efficiency rating supports continuous duty cycles.

Direct Mount Installation

The closed base design allows straightforward bolt down mounting on standard 56HZ patterns. No special tools are required beyond basic alignment hardware. The most common issue is wiring the dual voltage leads incorrectly, so verify the 115V or 208-230V connection diagram before energising.

Questions about this item

What voltage supply do I need to run the 2 HP 1725 RPM motor?

The motor operates on 115 V or 208-230 V AC; wire it to match the voltage available in your facility.

Will the 56HZ frame fit the mounting pattern on my existing compressor?

The 56HZ frame determines compatibility with specific compressors and pneumatic tools; verify your equipment requires this exact frame size before installing.

How can I confirm the motor is delivering its rated 84.5 % efficiency after installation?

Measure the input power at 115 V or 208-230 V and compare the mechanical output to the 2 HP rating; operation at the nameplate 1725 RPM under load indicates proper performance.
