An exemplary elevator machine frame includes a plurality of support surfaces configured to support at least one of a motor or a brake. A plurality of arms between the support surfaces maintain a desired alignment of support surfaces. At least one of the arms has a first cross section taken transverse to a longitudinal direction along a length of the arm at a first longitudinal location on the arm. That same arm has a second, different cross section at a second, different longitudinal location on the arm.
