METHOD AND MONITORING DEVICE FOR MONITORING THE CONDITION OF A MACHINE
In order to monitor the condition of a machine, current operating data relating to the machine are continuously captured and are taken as a basis for continuously simulating a current operating behavior of a machine component by a concurrent simulation module.

Detection of the first change pattern then causes a performance reference value to be updated with the current performance normal value. In addition, the respective current performance values are continuously compared with the current performance reference value in each case.

A method and a control apparatus for determining parameters for controlling an electric drive having an electric machine improve the start-up of the electric drive by applying a current indicator as a signal at three-phase winding connections of the electric machine, and measuring a d-component and a q-component of the stator voltage and of the stator current at the winding connections. In a first measurement step, a rotating current indicator is applied to the three-phase winding connections and the electric machine is oriented such that an exciter current in the q-axis assumes a minimum. In a second measurement step, when the rotor of the electric machine is stationary, a field winding of the electrical machine is short-circuited and a current indicator in form of a binary noise signal is applied to the winding connections. A stator impedance is then determined as a first control parameter.
A self-ventilated electrodynamic rotary machine includes a housing configured to at least partially axially enclose the rotary machine, and a fan connected in a rotationally fixed manner to a shaft on a ventilation side of the rotary machine and configured to generate a main cooling air flow when the shaft rotates about an axis. The fan includes a cover which is configured to direct the main cooling air flow onto the housing and is structured to improve cooling of the housing. An air guide element is detachably fixed to the cover to generate an additional cooling air flow. The air guide element, when viewed in a circumferential direction, has a segmented design and is configured as separate part for retrofitting to the cover depending on a thermal requirement of the rotary machine. --,
