Problems solved by technology

This leads to high production and installation costs, since usually several, ie at least three temperature relays or temperature sensors are required, which have to be mounted separately and connected together conductively and, if required, with a plastic pair. The stator core and the winding are encapsulated, especially sprayed, then the installation and connection of the components must be implemented before the encapsulation or sprayed

Embodiment Construction

[0013] In the different figures in the drawings, the same components are provided with the same reference signs.

[0014] For the ensuing description it should be clearly pointed out that all mentioned individual features can be used in any combination with one another, that is to say that these individual features are not dependent on the features in the respective independent claims nor in the respective dependent claims references in . Furthermore, those features which can only be seen in the drawing are also relevant to the invention, even if not specifically stated, ie they can likewise be combined in any desired combination with at least one other feature.

[0015] figure 1 The stator 1 according to the invention is shown highly simplified and schematically. As shown, the stator 1 comprises a ferromagnetic stator core 2 drawn with dashed lines, around which a stator winding 4 is wound. For the electrical control of the stator winding 4, in particular for commutation, ...

Abstract

The invention relates to a stator (1) for a brushless electronically commutated motor having a stator core (2) around which a stator winding (4) is wound and a control circuit (6) for controlling said stator winding (4) . The stator core (2) together with the stator windings (4) is enclosed in a molded envelope (10) made of a plastic material with a defined thermal conductivity (λSt) . Furthermore, a temperature sensor (12) is installed outside the envelope (10), and the control circuit (6) is designed to be able to use the temperature The temperature measured by the sensor (12) calculates the temperature in the region of the stator winding (4). Furthermore, the invention relates to a brushless electronically commutated motor with a rotor and a stator ( 1 ) as described above.

Description

technical field [0001] The invention relates to a stator for an electronically commutated (kommutiert) motor of the brushless (kollektorlos) type according to the preamble of claim 1, having a ferromagnetic stator core around which a stator winding is wound and for Control circuit (Steuerelektronik) for controlling the stator windings. [0002] Furthermore, the invention also relates to a brushless electric machine with a rotor and a stator of the above-mentioned type. Background technique [0003] This type of electronic DC motor is usually also called EC motor (EC = electronically commutated, electronic commutation) or BLDC motor (BLDC = brushless direct current, brushless DC). In practical applications, such a DC motor must be equipped to prevent Overheat protection device. For this, it is currently known to install so-called temperature relays, i.e. temperature-controlled switching elements, or temperature sensors such as PTC elements directly in the stator winding are...
