ABSTRACT:
A corrosion-resistant electric motor casing comprises a substantially cylindrical yoke and barrel, and a pair of brackets fixed to and closing the axially opposite ends of the yoke and barrel. The yoke and barrel comprises a first member substantially in the form of a hollow cylinder made of a material which is sufficiently ferromagnetic to serve as a motor yoke, and a second member in the form of a pipe of aluminmum fitted over the first member and covering the outer peripheral surface thereof. The motor casing is made highly resistant to corrosion without involving an increase in the weight and cost thereof.
