Marathon HGA Series Electric Motor

Standard HGA motors are three phase squirrel cage TEFC (Totally Enclosed Fan Cooled), with IEC frame sizes from 80 to 315, with CENELEC frame allocation as standard. They combine excellent electrical characteristics with the robust strength of cast iron.

The conservative rating of Marathon type HGA motors provides additional operational safeguards, ensures long unit life, and renders this series inherently suitable for most arduous mining, industrial or agricultural applications.

In adition to standard design, the range includes:

HGAB – Brake motors
HGAE – Hazardous location Ex e
HGAN – Hazardous location Ex nA
HGAD – Hazardous location Ex tD
HGABD – Hazardous location Ex tD, Brake motors
HGAS – Smokespill application
HGAC – Cooling tower application
HGAR – Airstream rated for Axial flow fans

All units are supplied with F Class insulation, with temperature rise being limited to less than 80K (unless otherwise marked). This provides the end user with a wide safety margin under general operating conditions.

In addition we also offer motors wound with H Class insulation, and temperature rise still limited to 80K.

HGAH – High ambient temperature application
HGAHS – H Class smokespill application
