5 CAST IRON THREE PHASE MOTORS 150 & 170 SERIES 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 EEV 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. Stainless steel "full fact" nameplate with information on motor efficiency and power factor. Includes wiring diagram, bearing sizes, and motor weight. Non-sparking fan. Small size reduces noise and enhances efficiency. Fan keyed to shaft. Heavy-duty cast iron frame, endbells and conduit box. 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 NEMAthree-phase motors, 1 HP and larger. 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 pressfitted and pinned to housing 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. 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 reliefs. Bearing caps protect against entry of grease into the motor. Dynamically balanced rotor assembly is keyed to shaft. Cast iron endplates for maximum rigidity and long bearing life. Steel fan cover for optimum strength. Cast iron cover available for severe service. Oversized cast iron conduit box is gasketed and may be rotated in 90 increments. NPT threaded entrance. 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 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. 575V 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. Cast iron mounting feet. Precisionmachined for accurate alignment. Dual mounting provisions (six mounting holes) on 184T, 215T, 256T, 286T, 326T, 365T, 405T, 445T, 447T and 449T frames.
