100-280 Frames Dc Machines

Product Profile of 100-280 Frames Dc Machines
Crompton Greaves, a part of the Avantha Group, and a conglomerate with the global footprint offers LAMINATED YOKE SERIES 100-280 FRAMES. LAMINATED YOKE SERIES 100-280 FRAMES have rated Output in kW at 1500 rpm from 1.2kw to 450kw according to the products. This motor is standardized by Standards EC34 - 1, BS 5000 PART 99, DIN VDE 0530, IS 4722. These motors find applications in diverse industries steel, paper, sugar, cement, rubber, textile, printing machines, plastic extruders, re-rolling drives and material handling. The salient features of this motor are:
  • Custom built motors of optimum design with wide range of ratings to select from, for any application/requirement of industry.
  • Light weight and lower GD sq value for swift mechanical response to meet frequent reversal.
  • Insulation superior to Class F with Class H VPI, temperature rise limited to Class F ensuring high insulation strength and protection from environment. Frames 100 to 280 are offered with class "H" insulation.
  • Fully laminated magnetic circuit construction offering excellent commutation - suitable for 6 pulse thyristor power supply.
  • High over load capacity, low field power and high overall efficiency.
  • Frames 315 to 630 are fully compensated to withstand high short time overloads under field weakening condition.
  • Sturdy mechanical construction
  • Compact, low weight and highly energy efficient.
  • Large size of bearing - for longer life and trouble free operations.
  • Special commutator design with fibre glass taper rings, light weight & low GD sq construction.
  • Constant force brush holders with longer brushes for excellent brush contact, better commutation and longer brush life.
  • Modular design allows flexibility of Terminal Box and F.C. unit position.
  • Minimised vibrations, noise and longer bearing life through minimized unbalance at every stage and precision balancing of rotors using state of art dynamic balancing machine to grade better than 1.0
  • Skewed rotor construction ensuring low noise and minimized torque pulsation at low speeds.
  • Electrical brazing of armature conductor to commutator riser connection for 315-630 frames and high temperature soldering for 100-280 frames for best mechanical and electrical joints.
  • Split throws armature winding for best commutation.
