Three-Phase General Purpose Motor
The Baldor-Reliance EM3156T is a three-phase general purpose motor rated at 1 HP with a 145T frame. It suits industrial machinery that requires continuous duty operation on a rigid base. The open drip proof enclosure and steel frame provide durability in controlled environments. Buyers needing a single-phase motor or a different frame size should select another model.
Voltage and Frequency Limits
This motor operates on 208-230/460V AC at 60 Hz with full load amps of 3.6 / 1.8 A. The nameplate speed is 1,155 RPM and the service factor is 1.15. Insulation class F supports a maximum ambient temperature of 40 degrees C. Installations outside these electrical or thermal limits will not perform as specified.
Installation and Common Issues
The rigid base mounting and ball bearings allow straightforward alignment on a flat surface. CW/CCW shaft rotation offers wiring flexibility for the application. Missing thermal protection means external overload devices are required by the installer. Incorrect voltage connection or inadequate ventilation are the typical causes of premature failure.

Questions about this item
Should I choose the 208-230 V or 460 V connection for my 1 HP motor?
The motor is dual-voltage; wire it for 208-230 V to draw 3.6 A or for 460 V to draw 1.8 A, matching your supply.
What does the 1155 RPM nameplate speed mean when the motor is loaded?
At full load the shaft turns at 1155 RPM, about 4.5 % below the 1200 RPM synchronous speed for a 4-pole 60 Hz motor.
How does the NEMA 145T frame limit mounting options?
The 145T frame fixes the bolt pattern, shaft height and keyway to NEMA standards, so the motor only fits 145T-compatible bases and couplings.
