Electric motor with improved frame cooled by an air flow

摘要

The invention relates to an air-cooled electric motor with a substantially cylindrical frame, closed by a front bottom and a rear bottom carrying bearings thereon for support of the drive shaft. The rear bottom extends in a peripheral wall projecting outwardly away from the frame wall and in substantial alignment therewith, to the free edge of said peripheral wall a cover being applied to delimit a chamber adapted to receive electric elements complementary to the motor.
