Abstract: Various embodiments of the teachings herein include a canned electrical rotating machine or liquid pump. The machine or pump may include a can made of a first material. The first material comprises, at least in a proportion of more than 50% by weight, a composite material with high-modulus or ultrahigh-modulus (HM/UHM) carbon fiber reinforcement.

Abstract: A rotor of a permanent-magnet dynamoelectric rotary machine includes a pot-type support unit that has at least one cylindrical wall, permanent magnets that are arranged on the outer periphery of the wall of the support unit, and substantially axially extending cooling ducts provided within the wall.

Abstract: An electric machine has a rotor on a rotor shaft. The rotor shaft is supported on bearings such that the rotor and the rotor shaft are rotatable around an axis of rotation. The rotor is surrounded radially on the outside by a stator, the stator by a casing. Covering elements are arranged at the axial ends of the rotor and stator, by which the rotor and the stator are enclosed with respect to the environment of the electric machine. One covering element is surrounded radially on the outside, and axially on the side facing away from the rotor and stator there, by an air guide element, the other covering element by an inner ring element. First and second cooling channels running axially are arranged in the casing or between the casing and stator. Rotor channels running axially are arranged in the rotor shaft and/or in the rotor.

Abstract: The disclosure relates to a weight-optimized, meridian-accelerated rotor including permanent magnets securely supplied with a required cooling during use. The disclosure further relates to a corresponding electrical machine, in which the problem of demagnetization of existing permanent magnets due to rotor temperatures that are too high is avoided. The rotor or the rotor of an affected electrical machine has an annular structure on the outside radius for receiving the permanent magnets. The rotor also has a conical hub structure on an inside radius and a plurality of at least rib-shaped or blade-shaped structures between the annular structure and the conical hub structure in order to form a mechanical connection of the annular structure and conical hub structure.

Abstract: A rotor (2) of an electrical machine (60) has a laminated rotor core (4). A fan (18), which is arranged at the end face in the laminated rotor core (4) is provided for cooling purposes. The fan has a fan blade (21) and a supporting element (20) for the fan blade (21), wherein the fan blade (21) extends by way of a first section (31) beyond the supporting element (20) in a first axial direction and extends by way of a second section (33) beyond the supporting element (20) in a second axial direction (34) which is opposite the first axial direction (32).

Abstract: The invention relates to a device for cooling a component (2) in a vehicle by means of a cooling air flow (4), wherein the device has at least one air inlet (11) and at least one air outlet (12), which are arranged such that the cooling air flow (4) is adjusted from the air inlet (11) to the air outlet (12) as a result of a difference in pressure produced during movement of the vehicle as a result of varying high flow velocities of the ambient air. The invention also relates to a method for cooling a component (2) in a vehicle by means of an above-named device.

Abstract: An apparatus and method for detecting breaks in a travelling threadline of a synthetic filament is described. The motion of the threadline is monitored for speed by means of generating an electrical current by passage of the threadline across an idler roll. Increases or decreases in the speed of the threadline change the frequency of the electrical current generated, thereby providing means for signaling threadline speed changes such as occur in breaks and wrapping of the threadline.
