DC MOTORS

CONSTRUCTION

• Standard four pole design for all frames ensuring optimum use of active materials.
• Best quality electrographite carbon brushes, robust & ample commutator design, Sturdy brush boxes 7-rocker ring construction.
• Skewed armature slots ensure smooth & quiet operation over wide speed range 15:1 ratio.
• Completely laminated field system including main poles, inter poles and yoke. Laminations are hot or cold rolled silicon steel sheets. This reduces iron losse3s & improves dynamic performance & commutation.
• Compensation windings are provided to neutralise armature reaction, prevention distortion of main field & ensure perfect commutation over a wide sped range & rapid load changes.
• Dynamically balanced rotor.

STANDARD FEATURES

• C.I. Frames in foot and flange mounting.
• Enclosures :

1. Screen Protected Drip Proof (SPDP)
