OMPM-DCE Series Permanent Magnet DC Motors are design for
long motor life with permanently lubricated ball bearings and are
TEFC (totally enclosed fan cooled). The OMPM-DCE motors have
provisions for mounting the OMDC-PU-E pick-up sensor directly
on the fan end of the shaft. All OMPM-DCE motors are
constructed from heavy duty gauge steel including frames,
endbells, mounting bases, junction boxes and covers. The
OMPM-DCE series DC motors are specifically design for use with
SCR controllers where applications require torque throughout the
application and speed range, as well as adjustable speeds. DC
motor voltage available are 90 and 180 volt.
