  • Patent number: 9685840
    Abstract: A BLDC motor for driving a cross flow fan in an air-conditioning application has an external rotor and an internal stator. The stator is a salient pole stator with insulated pole teeth and conductor coils. The inner diameter of the stator supports a single bearing. An electronic PCBA for control of the BLDC motor is optionally attached to the stator, all of which is encapsulated in a thermoset resin. The rotor comprises permanent magnet component(s) and a rotor frame. The rotor frame includes a stub axle that engages with the bearing element and features to provide torsional or rotational compliance between the rotor magnets and the fan. A level of compliance is provided between the bearing element and the stator to allow for angular misalignment between the rotational axis of the fan and the stator.

  • Patent number: 9675921
    Abstract: The invention first relates to an air filter attachment (4) for a turbomachine, in particular a side channel compressor, comprising a housing, comprising a filter material (8) arranged in a housing interior, and comprising an inlet (9) and an outlet (10) which are formed in the housing, which have a free opening cross section, and through which air is suctioned. The aim of the invention is to advantageously design a turbomachine comprising an air filter attachment. This is achieved in that the housing interior that has the filter material (8) extends laterally relative to the opening cross section of the inlet (9) and/or the outlet (10) in a non-uniform manner and in any case in a direction by a magnitude of 1½ or more times the dimension from a central axis (M) of the respective opening cross section to a periphery of the opening cross section in the direction. The invention further relates to a turbomachine, in particular a side channel compressor, comprising such an air filter attachment.
