Three-Phase Motor for Industrial Equipment
This Baldor-Reliance EM3559T is a 3 HP three-phase general purpose motor built for continuous duty in industrial machinery. It suits operations that need a 143T frame motor running at 3450 RPM on 208-230/460V AC power at 60 Hz. The steel frame and Class F insulation support demanding environments up to 40 Degrees C ambient temperature.
Rigid Base Mounting with Dual Voltage Wiring
Installation uses the rigid base mounting type with a closed base design. The motor accepts dual-voltage connections at 208-230V or 460V, drawing 7.2 or 3.6 full load amps respectively. Wiring must match the supply voltage exactly; incorrect connection will cause immediate failure. No thermal protection is included, so external overload devices are required by code.
Continuous Operation at 86.5 Percent Efficiency
Under sustained load the motor delivers its rated 3 HP with a 1.15 service factor and 86.5 percent nominal efficiency. Ball bearings and totally enclosed fan cooled enclosure maintain consistent temperature during continuous duty cycles. The CW/CCW shaft rotation offers flexibility for driven equipment. CSA and UR listings confirm compliance for industrial use.

Questions about this item
How can I verify the motor is running correctly after installation?
Check that the nameplate RPM reaches 3450 at 60 Hz and that the current draw settles near 7.2 A on 230 V or 3.6 A on 460 V under full load.
What ships with the motor and what must I source separately?
The motor itself arrives with a rigid steel base and ball bearings installed; you must supply three-phase power wiring, overload protection, and any coupling or pulley for the driven equipment.
Which voltage connection should I use for a 208 V supply?
Wire the motor for the low-voltage 208-230 V configuration, which draws 7.2 A at full load and matches the 1.15 service factor.
