Abstract

A device for acquiring operating parameters on electric motors with an arrangement that is influenced by an effect of at least one operating parameter of an electric motor. The arrangement is designed to store and display the effect. To obtain reliable information regarding the recyclability of the electric motor, the operating time and/or the number of motor starts can be detected by an electronic circuit and stored in a memory from which respective data can be read out and analyzed at a proper time.
