LEESON C6T17FB14D 1.5 HP 1725 RPM 208-230/460V 3-Phase TEFC NEMA 56 Industrial Electric Motor

Condition: Used. Shows normal-to-heavy industrial wear including scratches, paint loss, dust, surface oxidation, and rust on the shaft and mounting-base edges.

Description

The LEESON C6T17FB14D is a heavy-duty industrial three-phase AC induction motor rated at 1.5 HP, 1725 RPM, and 208-230/460 VAC at 60 Hz. It uses a TEFC (Totally Enclosed Fan Cooled) enclosure and is designed for continuous-duty industrial applications where a rugged, enclosed motor is preferred over an open-drip-proof design.

According to the visible nameplate, this motor is a NEMA Design B, three-phase unit with a 1.15 service factor, approximately 78.5% nominal efficiency, and 72% power factor. Its speed indicates a conventional 4-pole induction-motor design at 60 Hz.

This type of motor is suitable for fans, pumps, HVAC equipment, conveyors, machine tools, industrial blowers, mechanical drives, and other equipment requiring approximately 1.5 HP at around 1725 RPM.

Motor Shaft Rotation

This motor is electrically reversible by changing the appropriate three-phase lead connections according to the wiring diagram on the motor nameplate.

Motor Shaft Rotation: CCWSE/CWLE or CWSE/CCWLE — Reversible

• SE: Shaft End
• LE: Lead End

The actual direction depends on phase/lead configuration. Always follow the wiring diagram on this specific motor before energizing it.

Electrical Characteristics

The motor is designed for dual-voltage three-phase operation:

• 208-230 V: approximately 5.0 A full-load current
• 460 V: approximately 2.5 A full-load current
• 60 Hz
• 3 Phase
• 1.15 Service Factor

The terminal leads must be configured correctly for the available supply voltage. Because the terminal box is currently open in the provided photos, its connections and insulation should be inspected before installation.

Construction Features

The C6T17FB14D uses a rugged industrial construction with a TEFC housing. The motor body is enclosed while an external fan moves cooling air over the housing, providing better protection from ordinary dust and airborne contaminants than an open motor.

Notable features include:

• Totally enclosed fan-cooled construction
• Industrial cast/steel motor housing
• Rear cooling fan and protective fan guard
• Rigid foot mounting
• Keyed output shaft
• Dual-voltage winding configuration
• Reversible three-phase rotation
• Continuous-duty rating
• 1.15 service factor
• NEMA Design B torque characteristics
• Separate side-mounted electrical junction box
• Standardized NEMA-frame mounting geometry

Applications

This motor can be used in many commercial and industrial drive systems, including:

• HVAC air-handling equipment
• Belt-driven ventilation fans
• Industrial exhaust fans
• Blower assemblies
• Centrifugal pumps
• Circulation pumps
• Hydronic equipment
• Conveyors
• Gear reducers
• Machine tools
• Woodworking equipment
• Metalworking machinery
• Material-handling equipment
• General-purpose industrial machinery
• Process equipment
• Agricultural equipment
• Mechanical-room systems
• Industrial replacement-motor applications

For HVAC or blower applications, the actual CFM is determined by the fan/blower wheel, pulley ratio, static pressure, and system design, not by the motor alone. A reliable CFM figure therefore cannot be assigned to this bare motor without the driven equipment specifications.

Replacement and System Compatibility

The motor may serve as a replacement where the original equipment requires approximately:

• 1.5 HP
• 1725 RPM
• 208-230/460 V
• 3-phase power
• 60 Hz
• TEFC enclosure
• NEMA 56 mounting
• Rigid foot mount
• Keyed shaft

Before substitution, verify shaft diameter and length, shaft height, bolt-hole pattern, base dimensions, overall motor length, terminal-box position, required rotation, starting torque, and load characteristics.

Electrical ratings alone are not sufficient to guarantee mechanical interchangeability.

Cross-Referenced Models

Potentially related or functionally comparable LEESON models include:

• LEESON C6T17FB14D (1.5 HP, 208-230/460V, 1725 RPM, NEMA 56)
• LEESON C6T17FB14G / 110444.00 (1.5 HP, 208-230/460V, 1725 RPM, 56/56H)
• Other LEESON 1.5 HP general-purpose three-phase TEFC motors with 56/56H frame configurations

The suffix differences in LEESON model numbers can indicate production revision, frame/mounting details, electrical revisions, or other construction changes. Mechanical dimensions should therefore be checked before treating another suffix as a direct replacement.

Comparable Products

Comparable motors may be available from:

• Baldor / ABB — 1.5 HP, approximately 1725 RPM, 230/460 V, 3-phase TEFC
• Marathon — 1.5 HP, 1725 RPM, 3-phase TEFC general-purpose motor
• WEG — 1.5 HP, 4-pole, 230/460 V, 3-phase TEFC motor
• Century / Regal Rexnord — 1.5 HP, approximately 1725 RPM industrial motor
• Dayton — 1.5 HP, 3-phase, approximately 1725 RPM general-purpose motor

These should be considered functional comparisons rather than guaranteed drop-in replacements until mounting and shaft dimensions are confirmed.
