摘要： A stator for an electric motor includes a substantially hollow-cylindrical stator stack provided with wire windings and an end winding, which adjoins the stator stack in the axial direction. The stator stack includes a number of slots, wherein a coolant line is inserted into the respective slot. To improve efficiency of the electric motor, a section of the respective coolant line extends into the region of the end winding.

摘要： An electric machine includes a stator, a rotor interacting magnetically with the stator, a housing surrounding the stator and rotor, and a hollow shaft provided for arrangement of the rotor and mounted on the housing. A radial fan is mounted rotationally fixed on the hollow shaft on the ventilation side. A section of a fan blade of the radial fan extends axially away from the housing to a greater extent than the hollow shaft. A guide element with radially extending plate is arranged in the hollow shaft, wherein the plate is arranged axially further away from the housing than the end side of the hollow shaft on the ventilation side. An inner coolant flow can thus be delivered from the section of the fan blade out of the hollow shaft through a passage between the end side of the hollow shaft on the ventilation side and the plate radially outwards.

摘要： An installation for transporting fine-grained material to a consumer using two alternately filled and emptied pneumatic pressure vessels (3, 4) together with an outlet valve (12, 12') and a control nozzle (15, 15') in the material discharge pipe of each of the two pressure vessels. The control nozzles (15, 15') are connected to an air distributor (18) through which the control nozzle receives a reduced amount of compressed air when the material discharge pipe is shut off.With an installation such as this, a continuous and exactly metered delivery of fine-grained material is obtained without any mechanically moved parts in the delivery path and with a low rate of flow in the delivery pipe.
