Three phase motors totally enclosed for continuous duty, general purpose
applications. Standard on all these ratings is the exclusive Inverter
Rated Insulation System (IRIS). This provides superior protection
against voltage spikes induced by variable frequency drives. Many
superior mechanical features for both the motor and gearbox. Double
shielded ball bearings in the motor. Needle bearings in the parallel
shaft gearboxes and ball bearings in the Right angle (worm) gearboxes.
Steel conduit box provided as Standard. Complete gearmotor furnished
with high gloss hardened black enamel paint.
Application Notes: These
motors are designed with high temp insulation (Class F) to avoid over
heating when operated with a PWM inverter down to a 10:1 speed range
from the printed gearmotor output RPM.Refer to pages 104 to 106
detailing non-horizontal mounting. The torque values listed are the
recommended full load torque values for reasonable gear life.Overhung
load capacities shown are at the center of the output shaft.
