The cause of the problem of measuring the torque of synchronous and observed cars of an automobile traction electric drive is being solved. Issues of the relevance of the problem to be solved and methods of priority attention to the main coordinates of the electric drive are selected. The theoretical development of the sensor is based on the energy model of an electric machine in differential circuits of active and reactive power balance. The mathematical model of the sensor does not depend on the destabilizing factors of magnetic fields and the corresponding inductive elements. The key model variables in terms of total active power and angular velocity can be measured, and the top efficiency ratings of traction mechanisms (95%) are widely used to account for non-linear sensory losses. Information support of electronic sensors is based on the expansion of the traction electric drive, supplemented by measuring voltage converters of the three-phase circuit.
