Abstract
Abstract A system for mounting a motor driving a motor capstan includes a single flexible metal sheet which includes four bends along four spaced parallel flexure lines. The four flexure lines divide the sheet into five sections, including first and second end sections, first and second leg sections adjacent to the first and second end sections, respectively, and a motor support section disposed between the first and second leg sections. The first and second end sections are attached to a rigid support surface. The first and second leg sections have flanges to provide structural strength. The first and second leg sections are oriented at downward angles from the rigidly mounted surface. The motor support section is approximately parallel to the rigid mounting surface and includes an opening therein for accommodating the motor. The motor is attached to the motor support sheet by means of upper and lower clamping plates having opposed beveled surfaces and wedging means forced against the motor housing by the opposed beveled surfaces as the clamping plates are clamped together. The planes of the first and second leg sections extend below the motor support plate to intersect in a line which passes through a composite center of gravity of the motor, motor capstan, stainless steel sheet, and clamping plates. The first and second end sections are attached to the rigid support surface to prestress the flexible sheet along the four flexure lines so that the flexure sheet produces a predetermined resistance to angular displacement of the motor and motor capstan.
