Baldor manufactures an extensive range of large DC motors, keeping stocks in Australia.  All Torque Transmissions handles the full range, with some stocks held in Melbourne and some in Sydney.

Large DC Motorslarge dc motor

  • The range starts at 4.7kW and extends to 187kW
  • Designed for full thyristor control variable speed drives
  • Class ‘H’ insulation
  • Stock motors are supplied as force ventilated with blower
  • A wide variety of options and special designs are available
  • Custom motors up to 550kW also available

 

Specific Features

  • Class H insulation system with 200 degree Celcius materials throughout
  • High dielectric stability, with low moment of inertia armature for fast response
  • Designed to operate below NEMA Class F temperature rise for longer life and high overload capabilities
  • Armature is double dipped and baked with 100% epoxy varnish to ensure thermal conductivity, superior bond strength and chemical resistance
  • Field coils are 200 degrees Celcius polyester polyamide-imide coated magnet wire.  Bolt in pole assemblies facilitate fast in-field servicing
  • Rated for continuous duty (S1)
  • Silver-copper alloy commutator with high temperature mica insulation for maximum reliability even at increased temperatures
  • Riser connections are TIG welded for minimum resistance and maximum strength
  • 4 pole ‘straight shunt wound’ design with separate field excitation on frames up to B200
  • 4 pole ‘stabilised shunt wound’ design with separate field excitation on frames B225 and above
  • IP23 enclosure standard
  • High quality steel frame, annealed for optimum magnetic properties
  • Heavy duty steel feet welded to the frame for maximum structural integrity under adverse conditions
  • Heavy duty cast iron endplates
  • Precision brass brush holders provide accurate brush positioning and corrosion resistance
  • Stainless steel constant force springs require no adjustment and ensure accurate pressure over the brush life
  • Large removable brush inspection covers allow easy access to the commutator and brush equipment
  • High tensile stressproof alloy shaft designed to exceed NEMA specifications for belt loadings
  • Deep groove ball bearings, regreasing fittings and reliefs
  • Locked bearings construction permits a minimum of armature free-play and allows mounting of motor in any position
  • Forced air blower cooling (IC06) complete with filter and 3 phase ac motor mounted on commutator end
  • B225 and B250 frame motors are suitable for direct mounting of Baldor PRG / BTG or XPY tachometer-generators without additional accessory kits.  Tachometer mounting provision on all other frame sizes.
  • Thermostats fitted as standard for winding protection on frames B132 to B200.  Thermostats optional on frames B225 and B250
