For reliable performance in heavy-duty industrial applications, nothing beats the LEESON Heavyweights. With their cast iron construction and 1.15 Service Factor, they are ideal for "tough to handle" applications.
But that's only part of the story. LEESON 150 and 170-series cast iron motors are extremely versatile and can be field converted in minutes to a number of different configurations, including:
  • Severe Duty TEFC (using cast iron fan guard kit)
  • F2 mounting (by reassembly)
  • C face with rigid base (from stock or using C face kit)
  • D flange with base (using D flange kit)
    CSA certified under report number LR62104
    CSA Energy Efficiency Verification report number EEV78720-1
    UL recognized insulation system, file number E55555 and UL recognized construction, file number E57948 on all cast iron motors produced in June 2003 and later.

    LEESON’s Inverter Rated Insulation System (IRIS™) provides superior motor protection against voltage spikes induced by variable frequency drives. This total insulation system protects better than spike-resistant magnet wire alone. Specially formed phase insulation, cushioned and sleeved connections (from the leads all the way into the turns), and deep-penetrating, non-hygroscopic, high temperature varnish are just a few features contributing to the extra protection. All this plus second generation, spike-resistant magnet wire. The IRIS™ total insulation system is standard at no extra cost in all LEESON stock NEMA three-phase motors, 1 HP and larger.

    Note 150 and 170 Series Drip-Proof and TEFC motors in NEMA frames 180T thru 447T can be field converted, by reassembly, to F2 conduit box locations.

    • Premium efficiency WATTSAVER® motors.
    • Non-sparking fan. Small size reduces noise and enhances efficiency. Fan keyed to shaft.
    • Stainless steel "full fact" nameplate with information on motor efficiency and power factor. Includes wiring diagram, bearing sizes, and motor weight.
    • Heavy-duty cast iron frame, end bells and conduit box.
    • High torques for hard-to-start loads. Torques exceed NEMA performance standards. Energy performance verified by LEESON’s NVLAP-Certified testing laboratory.
    • 100% copper-wound Inverter Rated Insulation System is double-dipped and baked. Stator press fitted and pinned to housing. 1.15 Service Factor provides extra margin of power. Class F insulation system with Class B or lower temperature rise. Many suitable for 50 Hz operation at 1.0 service factor. Contact factory for details.
    • Dynamically balanced rotor assembly is keyed to shaft.
    • Lubrication fittings on each end of motor (254T frame and larger). New Exxon POLYREX® EM lubricant for extended bearing life. Oversized bearings. Slotted-head pipe plug relief's. Bearing caps protect against entry of grease into the motors.
    • Cast iron endplates for maximum rigidity and long bearing life.
    • Steel fan cover for optimum strength. Cast iron cover available for severe service.
    • 12 12-Lead Delta windings (254T to 405T frame and larger) for across-the-line or wye delta starts. (182T & 215T frame motors are dual voltage with nine leads. Motors above 405T frame are single voltage with six leads. 575 V motors have six leads, except 213T- 215T which have three leads) Permanently marked leads with lugs for easy connection. Normally-closed thermostat standard on WATTSAVER® designs.
    • Oversized cast iron conduit box is gasketed and may be rotated in 90° increments. NPT threaded entrance.
    • Cast iron mounting feet. Precision machined for accurate alignment. Dual mounting provisions (six mounting holes) on 184T, 215T, 256T, 286T, 326T, 365T, 405T, 445T, 447T and 449T frames.
    • Internal caps on shaft-end and lead-end bearings 254T frame and larger. 182T through 215T frame motors with C-faces have locked bearing on the shaft end only. Motors are suitable for all mounting positions.
    • One-way, corrosion resistant condensate drains. (TEFC models) release condensation and moisture.
    • Neoprene shaft slinger protects bearings by repelling moisture and other contaminants. Internal protection against rust and corrosion.
