1. An air-cooled dynamo-electric machine, comprising:
- a stator including a winding system which forms end windings at end faces of the stator; and
at least one monitoring element provided in an insulation layer or in an additional layer applied to the insulation layer of at least each said end winding for monitoring thane insulation thickness of the end winding.

Abstract
An air-cooled dynamo-electric machine, in particular an enclosed-ventilated dynamo-electric machine includes a stator with a winding system which forms end windings at the end faces of the stator. At least the end winding has at least one monitoring element in its insulation layer, or in an additional layer which is applied to this insulation layer, for the purpose of monitoring the insulation thickness of the end winding.

7. A method for checking an insulation state of an end winding of an air-cooled dynamo-electric machine, comprising:
-
sending signals to a monitoring element in an end winding of a winding system at an end face of a stator at predetermined time intervals; receiving return signals from the monitoring element; and evaluating the return signals to draw a conclusion about the insulation state of the end winding. - View Dependent Claims (8, 9)
