摘要:
A cooling system for an electrical machine is produced in the form of an extruded profile and has a plurality of webs which run in the direction of the extrudate of the extruded profile. Each web separates two adjacent cooling channels of the cooling jacket from one another. The cooling channels of the cooling jacket form a meandering cooling system. Passages of the cooling system which run perpendicular to the webs are formed by in each case one cutout in each of the webs at one of the end faces of the cooling jacket or by cutouts in end plates which are attached to the end faces of the cooling jacket.

摘要:
A communication method in an automation system, wherein the system comprises an access point and client terminals that receive downlink data sent from the access point and send uplink data to the access point, and the data transmission is divided into a master multiple receiver aggregation phase and more than one slave multiple receiver aggregation phases. During the master multiple receiver aggregation phase, the access point aggregates the data to be sent to the plurality of client terminals into one packet for transmitting in the downlink, and during the slave multiple receiver aggregation phases, the access point aggregates data in which errors have occurred when being transmitted during the master multiple receiver aggregation phase into one packet for transmitting in the downlink. The method can have strict control, through the access point and over the uplink and downlink data transmission, thus enhancing the certainty during automation communication and further reducing the cycle time.
