A method of evaluating a motor. Prior to testing the motor, the following factors are measured as essential properties of the motor, e.g. a correlation between a reference current and a motor current, reaction of the motor current, etc. in response to a variation of the reference current, a correlation between the reference current and a motor torque, temperature characteristics of the motor torque, a relationship between the torque, the number of rotations, efficiency of the motor, and so on. The measured essential properties include response delays of an evaluator and sensors, and influences of disturbances such as temperature. Data collected during testing are corrected on the basis of the measured essential properties using the reference currents as time criteria such that influences caused by response delays can be excluded. Thus, the performances of the motor can be precisely analyzed.

[ What is claimed is:] [1.] A method for processing original measurement data on a specimen motor, the original measurement data representing an operating status of the specimen motor when the specimen motor is actuated in response to periodically issued operating testing commands, the method comprising the steps of:collecting, through a preparatory test prior to the periodically issued operating testing commands, preparatory response delay information representing a delay in operation timings of the specimen motor with respect to issued timings of corresponding preparatory testing commands; andgenerating motor evaluation data by compensating the original measurement data with the preparatory response delay information.
