N/A
- 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.
