Small heater blower

Abstract: A motor with an external rotor (28) fits in a fan casing (22). Fan blades (30) on the external rotor convey air through the fan casing. An electric heat register (44) uses a detachable connection (38,42) like a locking connecting to make a releasable connection with the fan casing.

Electronic commutating electric motor has network rectifier for rectifying network changeover voltage to intermediate circuit-direct current voltage, and has commutating electronics for controlling three-standed motor coil

Abstract: The electronic commutating electric motor (1) has a network rectifier (2) for rectifying a network changeover voltage (U-N) to an intermediate circuit-direct current voltage (U-Z), and has a commutating electronics (4) for controlling three-standed motor coil. An integrated buck converter (10) is provided for reducing the intermediate circuit-direct current voltage that is supplied over the network rectifier.

Mini fan manufacturing method for use in air conditioning system, involves connecting plastic bearing part to shaft by injection molding of two components to plastic material, and arranging ferromagnetic particles of magnet to material

Abstract: The method involves connecting a plastic bearing part (64) to a shaft by injection molding of two components to a plastic material. Hard ferromagnetic particles (74) of a rotor permanent magnet are arranged to the plastic material such that a part of a transitional area between the bearing part and the rotor permanent magnet is formed by an integral joint. The rotor thus formed is embedded in a mini fan. An independent claim is also included for a mini fan, comprising fan blades.

Two-strand electronically commutated motor operating method for actuating ventilator, involves providing output stage for influencing current feed of cable in stator, where DC intermediate circuit with capacitor supplies current to stage

Abstract: The method involves providing an output stage (122) for influencing the current feed of a cable in a stator. A DC intermediate circuit (170) with a capacitor (178) supplies current to the output stage. A commutation process is executed for a predetermined commutation time point in the output stage. The commutation time point is determined based on the energetic recovery system in the capacitor. An independent claim is also included for an electro motor comprising a rotor.
