Abstract
The invention relates to a stator (16) of an electrical machine (10), to an electrical machine (10), and to a method for producing same, particularly for adjusting movable parts in a motor vehicle, comprising a pole casing (15) to the inner wall (115) of which winding holders (36) carrying electric coils (17) are applied, the winding holders (36) comprising a stator tooth (120) which is formed on a yoke element (118) which is radially applied to the inner wall (115), and an insulating mask (61) is arranged on the winding holder (36), which insulates the electric coil (17) from the winding holder (36), and the insulating mask (61) extends with an axial projection (102) axially over the yoke element (118), the axial projection (102) being radially applied to the inner wall (115) of the pole casing (15) with a shoulder (108) extending in the peripheral direction (2).
