EM3714T-5

What type of industrial motor is this?

This is a three-phase AC induction motor designed for general-purpose industrial applications. It has a totally enclosed fan-cooled enclosure, rigid base, and NEMA 215T frame.

What is the rated power output?

The motor has a rated output of 10 hp at 60 Hz.

What voltage and current does the motor require?

The EM3714T-5 is a single-voltage motor rated for 575 V AC, three-phase operation. Its full-load current is approximately 9.8 A.

What is the rated operating speed?

The motor has a rated full-load speed of 1,765 rpm and a synchronous speed of 1,800 rpm at 60 Hz.

What enclosure type does the motor use?

It uses a totally enclosed fan-cooled enclosure, commonly abbreviated as TEFC. This construction limits the entry of external contaminants while an external fan provides cooling.

What frame size and mounting arrangement are used?

The motor uses a NEMA 215T steel frame with a rigid base and an F1 mounting arrangement. These details should be checked against the installation dimensions before replacement.

Is the motor suitable for continuous operation?

Yes. It carries a continuous-duty rating at a maximum ambient temperature of 40 degrees Celsius under its specified operating conditions.

Can the motor be operated with a variable-frequency drive?

Yes. The motor is marked VPWM inverter ready. Its nameplate indicates a 10:1 constant-torque range and a 20:1 variable-torque range from 3 to 60 Hz.

What are its efficiency and power-factor ratings?

The nominal NEMA efficiency is 91.7% at rated load, and the listed power factor is 83%.

What service factor does the motor have?

The motor has a 1.15 service factor. Its listed service-factor current is approximately 11.2 A.

What starting method is specified?

The specified starting method is direct on line. The motor has NEMA Design A characteristics, KVA Code J, and a typical starting current of 75.1 A.

Can the direction of rotation be changed?

Yes. The shaft rotation is reversible. For a three-phase motor, rotation is normally reversed by interchanging two incoming phase connections, following the applicable connection diagram and site procedures.

What insulation class is used?

The motor uses Class F insulation and is rated for continuous operation in a 40-degree-Celsius ambient environment.

What bearings are fitted?

The nameplate identifies a 6307 bearing at the drive end and a 6206 bearing at the opposite drive end. The specified bearing grease is Polyrex EM.

Does the motor include thermal or feedback devices?

No integrated winding thermal device, bearing thermal device, feedback device, heater, or vibration sensor is specified for this model.

Is it intended for hazardous locations?

No hazardous-area class or group is assigned to this motor. It should therefore be treated as a general-purpose motor rather than a hazardous-location motor.

What shaft dimensions should be considered during installation?

The motor drawing specifies a shaft diameter of approximately 1.375 inches and a 5/16-inch square key. The keyed shaft section is approximately 2.38 inches long.

Is a C-face configuration possible?

A compatible 37-3301 C-face kit is listed as an accessory. Mechanical dimensions and the driven equipment interface should be checked before selecting this configuration.
