Abstract
A torque measuring apparatus is described that comprises a chassis, a reversible electrical motor having a motor housing and a rotatable output shaft projecting from one end of said motor housing, motor mounting means mounting said motor housing for rotation relative to said chassis, means for connecting said motor output shaft to a rotatable component of a device to be tested, whereby energization of said motor will cause said output shaft to rotate and apply a torque to said rotatable component and the resistance to rotation offered by said rotatable component will result in a reactionary torque that causes said motor housing to rotate relative to said chassis, means responsive to rotation of said motor housing for generating a signal representative of said reactionary torque, and means for converting that signal into a measure of the torque applied by said motor output shaft to said rotatable component.
