CMG SGA Series Electric Motor
Standard CMG SGA Series Electric Motor is three phase squirrel cage TEFC (Totally Enclosed Fan Cooled), with IEC frame sizes from 71 to 355, with CENELEC frame allocation as standard. It combines excellent electrical characteristics with the robust strength of cast iron. The standard design includes single speed 2,4,6 and 8 pole as well as a comprehensive selection of 2 speed motors.
The conservative rating of CMG type SGA motors provides additional operational safeguards, ensures long unit life, and renders this series inherently suitable for most arduous mining, industrial or agricultural applications.
Note: The SGA range of motors are being phased out in favour of the new improved efficiency HGA motors.
