Abstract

A small electric geared motor is contained in a housing (1). The housing is of two-part construction comprising an attachment plate (2) and a cover (3) which is securable to the plate (2) by tabs (7) punched out of the plate. Other tongues (4, 5, 6), also punched out of the plate, form carriers for mounting parts of the motor in the housing. When the plate is made from a ferromagnetic material, the bent up tongues (4, 5) act, together with the plate (2), as a magnetic flux return path for the magnetic elements of the motor. <IMAGE>
