摘要： A fan (16) comprising a hub (24) having a central axis (22); a plurality of interlock blade elements (26) connected to the hub (24) by means of an interlock (38, 52) such that each interlock blade element (26) is prevented from moving in a radial direction with respect to the hub (24); and an end blade element (28) positioned on the hub (24) between two interlock blade elements (26), the end blade element (28) being fixed to the hub (24) to prevent movement of each interlock blade element (26) in a circumferential direction of the hub (24). A synchronous machine (10) comprising a fan (16), a method of producing a fan (16), and a method of producing an interlock blade element (26, 28) for a fan (16), are also provided.

摘要： An electrical machine is provided comprising at least one random wound coil (10) out of a winding wire (1) comprising a conductor (2), and an insulation layer (3) surrounding the conductor (2) along a longitudinal direction thereof. The winding wire (1) comprises a conductive layer (4) surrounding the insulation layer (3) along a longitudinal direction thereof. Due to the conductive layer (4) the coil is grounded and partial discharges and bearing currents are reduced.

摘要： A winding wire (1) of a coil for a random-wound stator (20) is provided. The winding wire (1) comprises a conductor (2), an insulation layer (3) surrounding the conductor (2) along a longitudinal direction thereof and a conductive layer (4) surrounding the insulation layer (3) along a longitudinal direction thereof. Whereby the conductive layer (4) has a volume resistivity in the range of 0,1 - 10.000 ohm cm. The corresponding manufacturing method (30) of such a winding wire (1) and a random-wound stator (20) is provided. The random-wound stator (20) comprises a stator body (21) and random wound coils (10) out of such winding wires (1).
