An electric machine with a rotor (4) rotatably disposed within a stator (2) has a plurality of permanent magnets received in the rotor body of the rotor. Rotor body plates are stacked so as to form at least two first channels (31) extending inside the rotor body from one axial end of the rotor to an opposite axial end thereof and having an opening (33) to the exterior of the rotor body in an end surface of the latter at at least one of these axial ends, and at least one separate second channel (32) associated with each first channel and connecting the respective first channel to a space circumferentially surrounding the rotor and separating the rotor and the stator by opening at the periphery of the rotor body so as to upon rotation of the rotor throw air out from said second channel to said space for cooling the rotor body.

Systems and methods provide for transmitting updates in an Internet Protocol Television (IPTV) environment towards a client. The method includes: maintaining the updates in a data hierarchy of updates; receiving a first message identifying a client; retrieving information associated with the client; determining which updates are relevant to the client by matching the information associated with the client to the data hierarchy of updates; and transmitting a second message toward the client with information associated with the determined updates.
