The motor frame is made of cast iron, and the standard design includes cast iron feet, bearing housing, and terminal box. Integrated cast iron feet provide rigid mounting and minimize vibration.
Motors can be supplied for foot mounting, flange mounting,and combinations of these.
Motors that will be operated in very humid or wet environ - ments, and especially under intermittent duty, should be provided with drain holes. The IM designation, such as IM 3031, determines the intended mounting arrangement for the motor.
