Flowpak motors are part of an integrated range of induction machines, manufactured in a modern production facility dedicated to total quality.

Flowpak is a range of totally enclosed fan cooled cage induction motors available horizontally or vertically mounted for connection to supply voltages up to 6.6 kV, outputs upto 800 kW.

The Impak range has been designed to provide the maximum variety of cooling forms and enclosures, whilst still utilising
standardised electrical components.

Two stator frames have been developed for each frame size: a horizontal foot mounting frame, mounting designation IM 1001, and a vertical flange/skirt mounting frame, mounting designations IM3011/3611.

The horizontal foot mounting frame has an open top with machined faces to accept the cover or heat exchanger. The vertical flange/skirt’ mounting frame has two open sides with similarly machined faces.

The specified range of cooling forms and enclosures is available on each mounting arrangement. The first part of this publication details the mechanical features while the second part deals with electrical information.

  • Fabricated Robust Steel construction for frames.
  • Uniform internal cooling circuit.
  • Axial Cooling for smaller ratings, both radial and axial ventilation for larger ratings.
  • Basic mounting dimensions as per IS.
  • Class ‘F’ insulation system, both Resin rich & Resin poor (VPI) varieties available.
  • Rotors are dynamically balanced.
  • Rotor bars are brazed with end rings by One Shot Brazing process.
  • Environmentally friendly motors to meet all Drives.
  • Fault tested Phase Segregated Terminal box.
  • RTD, BTD, Dial type Temperature indicator available.
  • Separate Terminal Box available for Neutral point, RTD, BTD termination purpose.
  • Provision for Magnetic Slot Wedge to improve Efficiency, Power Factor and improve Electromagnetic noise
    Provision for special Epoxy paint system.
