More motors added
to this product line
This company has added 98 new ratings
to its Super-E motors with Internal
AEGIS Bearing Protection Ring
(photo). The additional ratings expand
the existing four-pole line of TEFC &
ODP designs through 100 hp, and add
a generous offering of two- and sixpole
models as well. Also, 575-V TEFC
motors were added, 1-50 hp, as well
as TEFC & ODP close-coupled pump
motors. While most shaft-ground applications
use a shaft ground on the
outside of the motor, the Super-E has
the grounding ring factory installed
internally on the motor. This internal
design minimizes exposure to the outside
elements and keeps the grounding
ring from being damaged by external
forces, says the manufacturer. Applications
include heating, ventilation and
air conditioning (HVAC) blower and
fan motors, pump motors and other
general-purpose applications using
an adjustable-speed drive. - Baldor

2 hp. It features adjustable minimum
and maximum speeds, adjustable acceleration
and deceleration, and display
options include decimal point positions
and intensity. The pulse input
capacity for speed feedback is 50,000
pulses per minute (833 Hz). Non-volatile
memory in the device provides
programmable power-on initial settings
and allows all custom settings
to be stored for future use. - Omega

The motors in these blowers
are explosion proof
Rotron EN and CP regenerative blowers
incorporating explosion-proof a.c.
motors (photo) provide ideal solutions
for a wide range of environmental remediation
and chemical processing
applications. These motors are UL and
CSA approved for Class 1 Group D

explosive-gas atmospheres to promote
safe operation in potentially hazardous
locations. Typical applications include
spot sourcing, vent header off-gassing,
landfill gas recovery and scrubbing, to
name a few. The explosion-proof motors
can accommodate international
voltage and frequency requirements,
and can deliver the power necessary
to satisfy the most demanding applications,
says the company. - Ametek

These brushless motors
are very effi cient
In January, this company introduced
its next generation design of 3- and
5-hp PremiumPlus+ motors (photo,
p. 56). Gen2.0 brushless permanentmagnet
motors driven by variable
frequency drives (VFDs), boast motorCHEMICAL
