DCS Baldor Reliance Motors 1 400

November 12, 2021

 

Baldor-Reliance industrial electric motors are available for most general purpose applications and processes. However, some AC Variable Speed applications require high performance capabilities including constant torque down to zero speed, wide constant horsepower range, high response applications that require low inertia rotors, or high speed capabilities. The RPM AC motor is most suitable for tough variable speed industrial applications where high performance, and power density (compact size and weight) is most important. RPM AC laminated frame motors are available in both standard induction and ultra high-density Interior Permanent Magnet (IPM) versions.

Features:

  • Extensive HP range (up to 1750Hp or 1305kW)
  • Square laminated steel frame
  • Wide CT (constant torque) speed range is standard; wide CHP (constant Hp) is available
  • Power Density:  up to 3 frame sizes smaller than traditional AC motors
  • IPM rotor design delivers IE5 level efficiency  
  • Corona free insulation Class H
  • Optimum pole design
  • Thermal Protection 3 N.C. thermostats (1 per Phase)
  • Integral shaft grounding brush included as standard
  • Insulated bearing on ODE (RL5800 offers insulated bearing on both ends)
  • PLS (Positive lubrication system)
  • Wide variety of enclosures (DPFV, TEBC, TEAO-PB, TENV, TEFC)
  • Oversize, rotatable mill conduit boxes
  • Quick ship program available thru web-based configurator
  • Provisions for ABB Ability condition monitoring
  • QR code on nameplate for motor details and drive set-up information

 

Common Industries:

  • Steel mill
  • Pulp & paper
  • Oil and gas
  • Plastic and rubber
  • Converting
  • Automotive
  • Class 1 Division 2 hazardous locations

 

Common Applications:

  • DC replacement
  • LAC replacement
  • Center wider
  • Roll-out tables and pick duty lines
  • Extruders
  • Crane and hoist
  • Oil drilling
  • Test stands low/high speed
  • Tension reels
  • Traction motor
  • High vibration presses
  • Dynamometers
