A segmented stator has a plurality of individual teeth () connected to one another in the direction of rotation. Each individual tooth () has a connecting portion () to produce a nonpositive mechanical connection with at least one directly adjacent individual tooth (). The respective connecting portion () has a groove-shaped fastening contour (), at least on one connecting side (), facing toward the directly adjacent individual tooth (). The fastening contour () of an adjacent individual tooth () can be connected to its connecting portion (), such that a nonpositive connection is produced which ensures a magnetic flux.

The invention concerns a housing of a fan with an external covering, wherein the housing comprises a housing body to accommodate fan components, and a radial exterior face of the housing body is surrounded by the external covering in the circumferential direction over its full surface, so that a radial exterior surface of the housing is formed by an exterior surface of the external covering, and the external covering is detachably fastened to the housing body.

Multipart housing of a fan

The invention relates to an electric motor comprising an electronics housing having motor electronics accommodated therein and a stator housing arranged axially at a distance from the electronics housing, wherein, axially between the electronics housing and the stator housing there is arranged a twin-flow cooling wheel which, during operation, generates a first cooling air stream along the electronics housing and a second cooling air stream along the stator housing and/or at least one bearing shield adjoining the stator housing axially.

Electric motor having improved cooling

An electronics unit and an electromotor with such an electronics unit is provided with a sealing arrangement which seals an interface structural group mounted on a printed circuit board against an inside of the electronics housing as well as on the front side in the area of the plug interface in such a manner that the inside of the electronics housing is sealed against the entrance of a liquid even in the not-in-use state of a connection box of the electronics unit.

Electronics unit

A housing for a fan or blower, in particular an axial fan, includes a wall ring () having an inlet nozzle section (), an outer diffuser () having an inlet flow opening () and an outlet flow opening (), and a holder for an electric motor () of the fan. The holder is arranged in an inner space of the housing. The outer diffuser () is formed by at least two partial ring sections that are connected to the outer circumferential surface via mechanical connection elements. The holder includes several struts () that are fastened to an inner circumferential surface of the outer diffuser () by one end, are circumferentially spaced apart, and are fastened in the edge region of the inlet flow opening (). The struts can be installed by their other end to a motor flange () of the motor housing () of the electric motor ().

Housing for an axial fan

A diffuser () for a fan () of axial, radial or diagonal type of construction, has an inlet opening () and having an outlet opening () for a gaseous medium which flows through a diffuser interior (I), which is enclosed by an outer housing (), in an axially oriented main flow direction (S) from the inlet opening () to the outlet opening (). The cross section of the diffuser interior (I) increases from the cross section () of the inlet opening to the cross section () of the outlet opening (), wherein the outer housing () forms an outer diffuser part (AD) which delimits the diffuser interior (I) to the outside. Along the main flow direction (S), the cross section of the outer diffuser part (AD) changes from a circular cross section () at the inlet opening () to a non-circular cross section () at the outlet opening ().

The present invention concerns an electronic housing for an electric motor, consisting of a housing holder part with a housing floor and a housing wall comprising the housing floor. A housing opening lies opposite the housing floor. Arranged in the housing holder part is a motor electronic component with an electronic printed circuit board, which is arranged parallel to the opening plane of the housing opening. Detachably arranged on the electronic printed circuit board or on the motor electronic component, on a side of the electronic printed circuit board facing away from the housing floor is a contact protecting component, which covers this surface, from an electrically insulating material, which has at least partially a grid structure as an air outlet.

Multi-piece housing fan

A motor, comprising an electronics housing having integrated motor electronics, a stator, and a rotor. The stator comprises a stator bushing and a laminated stator core having motor windings. The stator bushing is arranged axially between the electronics housing and the rotor. The motor according to the invention has an air-conveying element connected to the rotor in a rotationally fixed manner and at least one axially extending passage opening arranged in the stator bushing. The air-conveying element is arranged axially between the stator bushing and the rotor and has a circumferential axial intake opening on the side of the stator bushing. During motor operation, the air-conveying element sucks in an axial volumetric air flow at an external wall of the electronics housing through the intake opening and the passage opening.

Electric fan

A stator unit for an electric motor, in particular an external rotor motor, includes a stator with a stator laminate stack and stator windings and a stator bushing and a stator flange which is formed at one end. A housing flange of a housing for accommodating a motor controller or the like is fastened on the stator flange, and with motor connection contacts, which run from the stator through through-openings in the housing flange, and with fastening means, which run through fastening holes in the housing flange and are fastened in the stator. A sealing disk is arranged between the stator and the housing flange. The sealing disk has sealing regions made from elastic plastic, which are arranged and designed in such a way that direct and/or indirect sealing of the through-openings and/or the fastening holes is provided against the ingress of moisture.
