JM
PUMP AC MOTORS
SINGLE & THREE PHASE
RIGID BASE
RIGID BASE
General Specifications:
Designed
for continuous duty service on close-coupled pumps using NEMA JM mounting
provisions. All motors have a rigid mounting base and NEMA JM pump shaft.
Mechanical Features:
Open drip-proof construction with cooling air exhausts at the shaft end
for maximum cooling. Oversized locked bearing on shaft end limits axial
shaft movement. A drip cover is supplied with 143-5T and 213T steel frame
motors, for use when mounting the motor vertically with rigid base. Drip
covers for 182-4T frame motors are also available as an accessory
item. LEESON 182-4T frame motors have enclosed endshields as standard
with vents meeting 12° drip-proof requirement.
Electrical Features:
High efficiency copper windings with NEMA 1.15 service factors. UL and
CSA recognized designs.
LEESON's Inverter
Rated Insulation system (IRIS™)
provides superior 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 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.
