COOLING AN ELECTRICAL MACHINE

An electrical machine includes a stator and a rotor disposed in a housing of the electrical machine. The stator includes windings having a first set of end turns at a first end of the stator and having a second set of end turns at a second, opposing end of the stator. The stator has a substantially...

Summary:An electrical machine includes a stator and a rotor disposed in a housing of the electrical machine. The stator includes windings having a first set of end turns at a first end of the stator and having a second set of end turns at a second, opposing end of the stator. The stator has a substantially tubular shape and an interior lateral surface. The rotor extends through the interior of the stator. A flow inlet into a volume in the housing about the first end turns is located radially outside of the interior lateral surface of the stator. A flow outlet from the volume in the housing about the first end turns is located radially outside of the interior lateral surface. The inlet and the outlet are cooperatively arranged to communicate a flow of fluid substantially transverse across the first end of the stator. Una máquina eléctrica incluye un estator y un rotor colocados en un alojamiento de la máquina eléctrica. El estator incluye bobinados que tienen un primer conjunto de espiras de extremo en un primer extremo del estator y que tiene un segundo conjunto de espiras de extremo en un segundo extremo opuesto del estator; el estator tiene una forma sustancialmente tubular y una superficie lateral interior; el rotor se extiende a través del interior del estator; una entrada de flujo hacia un volumen en el alojamiento alrededor de las primeras espiras de extremo está ubicada radialmente fuera de la superficie lateral interior del estator; una salida de flujo desde el volumen en el alojamiento alrededor de las primeras espiras de extremo está ubicada radialmente fuera de la superficie lateral interior; la entrada y la salida están acomodadas cooperativamente para comunicar un flujo de fluido sustancialmente transversal a través del primer extremo del estator.
