Acceleration method of the IM torque-speed characteristics measurement

The paper deals with practical realization of the acceleration method for the torque-speed characteristics measurement of the tree-phase induction motor. Reached results are compared with the characteristics measured on the dynamometer. The authors propose to use B-splines for the processing of measured data Both their application and reached results are shown for the actual case. Further, the authors propose the measuring method of the moment of inertia of the rotor itself from the running up at the use of various numbers of additional flywheels.
