ABSTRACT:
The invention is a mechanism that measures, at any rotational speed, the torque transmitted from an electric motor rotor to an motor shaft and transfers the electrical characteristics representing the measured motor torque to slip rings external to the motor housing. The motor housing supports the motor shaft in bearings. The motor rotor is attached to the motor shaft by torsionally compliant structure, and the motor rotor is radially supported relative to the motor shaft by bearings which maintain the motor air gap when the torsionally compliant structure deforms. The rotational angular deformation of the torsionally compliant structure is measured by deformation measurement means within the motor housing. Electrical conductors are passed through a spacer in the form of a cylindrical shaft sleeve between the motor shaft and one of the motor bearing races to slip rings external to the motor housing. The angular deformation between the motor rotor and motor shaft is transformed to a voltage proportional to torque by an electronic circuit.
