Dayton 31LH34 Three-Phase Motor 2 HP 56H 230/460V
Three-phase 2 HP motor with 56H frame, 230/460 V dual voltage and 85.5 % nominal efficiency
- 2 HP three-phase power drives demanding HVAC equipment
- 5 % nominal efficiency reduces energy consumption
- Dual 230/460 V voltage suits multiple supply configurations
- Open drip-proof enclosure with steel frame resists contaminants
- 15 service factor handles continuous overload conditions
Three-Phase General Purpose Motor
The Dayton 31LH34 is a three-phase general purpose motor rated at 2 HP with a 56H frame. It operates on dual-voltage 230/460V AC at 60/50 Hz and carries CSA and UL listings. The open drip-proof enclosure and steel frame suit indoor industrial environments.
Ideal for continuous-duty industrial drives
This motor suits conveyor, pump and fan applications that require continuous duty at 3510 RPM nominal speed. Buyers needing integrated thermal overload protection or a totally enclosed enclosure for wet or dusty conditions should look elsewhere.
Dual-voltage operation with 1.15 service factor
Full-load currents are 5.3 A at 230 V and 2.7 A at 460 V, with a 1.15 service factor providing modest overload headroom. Nominal efficiency reaches 85.5 percent. Operation is rated up to 40 °C ambient; higher temperatures or frequent starting cycles will reduce service life.

Questions about this item
What three-phase supply voltage must the installation provide for this 230/460 V motor?
The motor is rated for 230 V or 460 V three-phase AC at 60/50 Hz.
Will the 56H frame and rigid base match the mounting pattern on my existing 56-frame equipment?
The 56H frame shares the standard 56 bolt pattern; the rigid base adds a fixed foot mount.
How can I confirm the motor is delivering its rated 2 HP after wiring?
Measure full-load current — it should read near 5.3 A at 230 V or 2.7 A at 460 V.
