Abstract

An electric machine (3) comprises a number of sensors (9) and a recorder unit (15) for the signals (SIG), recorded by the sensors (9). According to the invention, the recorder unit (15) comprises a web server unit (16) with at least one data interface. Corresponding sensor data (SD) may be read out with the sensor signals (SIG) from the recorder unit (15) via the data interface. The data interface is particularly a LAN, USB or Firewire data interface using a TCP/IP data transport protocol.
