Electric dynamometer

Patent ·
OSTI ID:5381540
An electric dynamometer which includes a rotor mounted for rotation on a shaft and a stator surrounding the rotor, the stator including a yoke surrounding the rotor in radially spaced relation therewith, and a loss drum disposed between the yoke and the rotor so as to be rotatable 360/sup 0/ about the rotor. An electric motor is coupled through its rotor to the loss drum so as to rotate the loss drum therewith. A stator of the electric motor is fixed to the yoke, and the yoke and stator of the motor are supported for rotation about the respective rotors. A torque detector is fixed to the stator of the motor so as to measure the combined torque exterted on the yoke and the stator of the morot about the rotors.
