LEESON's Wattsaver® 170 Series motors meet or exceed the 1997 efficiency levels mandated by EPACT '92 as well as the standards of most utility rebate programs. With the same robust mechanical features as our 150 Series, the 170 Series WATTSAVERŪ motors will continue saving energy for years to come.
Totally enclosed fan-cooled, 3 through 100 HP
Drip-proof, 7.5 through 50 HP
1.15 Service Factor
Field converts to severe duty, C face or D flange
Nameplate lists full load and 3/4 load efficiencies. Test method IEEE 112B
Suitable for inverter duty. Normally closed thermostats are standard
Carton : Motors are enclosed in a plastic bag to protect from moisture. Motors of NEMA frame 324T and larger are crated. Smaller frames are shipped in a wood frame reinforced carton with pallet.
Carton Label : Each carton or crate has a full fact carton which provides the model number, catalog number, weight, HP, phase, Hz, frame, RPM, voltage, and enclosure.
Name Plates : Stainless steel nameplate with connection diagram, power factor, efficiency, bearing size and location, motor weight, electrical code, insulation class, ambient temperature, voltage, amperes, speed, service factor amps, duty, frame size, hertz and unique serial number.
Paint Finish : Standard efficiency motors finished with primer and LEESON blue paint. Premium efficiency motors finished with primer and chemical-resistant LEESON green epoxy paint.
Insulation : Class F insulation. Double-dipped and baked. Motors operate within Class B temperature rise limits (70 C for drip proof, 90 C for TEFC).
Lead Wires : Lead material is cross linked polyster. The stasndard leadwire length is 6 to 8 inches into the conduit box. They are permanently marked and terminate with connection lugs.
Service Factor : Drip-proof and TEFC motors have 1.15 service factors at 60 Hz.
Thermostats : Premium efficiency drip-proof and TEFC WATTSAVER designs have normally closed thermostats on the winding ( with Red leads into the conduit box) for inverter service and over-temperature alert.
Torque : Motors are nameplated NEMA Design B. Torques, however, exceed NEMA Design C torques (except 3450 rpm) but are nameplated as Design B.
Voltage Rating : NEMA 182T through 215T are 9 lead motors and are rated for 208-230/460 volts, 60 Hz, three phase. NEMA 254T and larger are 12 lead motors and rated 208-230/460 volts, 60 Hz, three phase. Motors rated 125 HP and larger are single voltage 460 volts, 60 HZ, three phase.
Salient Features Meets or exceeds the 1997 mandated efficiency standards.of the Energy Policy Act of 1992. Also, meets or exceeds efficiency requirements of most electric utility rebate programs.
Notes LEESON 150 & 170 Series Cast Iron motors are extremely versatile and can be field converted in minutes to a number of different configurations.
Severe duty (TEFC only, using cast iron fan guard kit)
F2 mounting (by reassembly)
C face with rigid base (using standard C face kit)
