The invention relates to a device () for accommodating an electric motor (), particularly a blower motor for a heating or air-conditioning system, comprising an essentially pot-shaped accommodating housing () serving as a motor housing and having an accommodating opening () in which the pole casing () of an electric motor () can be inserted while at least partially projecting inside. The inventive device also comprises a retaining flange () mounted on the accommodating housing () and serving to fasten the motor housing () to a supporting element, and comprises a control and regulating unit () mounted on the retaining flange () and serving to operate the electric motor (). The invention provides that the accommodating housing () has, in the peripheral direction, at least one flattened area (), which differs from a circular shape while corresponds with at least one flattening () of an outer contour of the control and regulating unit (). The invention also relates to an electric motor (), particularly a direct-current motor having at least two permanent magnetic poles () and a pole casing () serving as a magnetic return ring and having at least one flattening () on the periphery of the pole casing, for use in a device () of the aforementioned type.

Method for accomodating an electric motor

An overload protection for electric motors, includes a one-piece suppression choke in which the connecting point to be broken is produced by means of at least one connecting point between the connection lug of the motor and a respective connecting element of the suppression choke, wherein the connection lug exerts an adjustable mechanical stress on the connecting point, thus reliably assuring a break when the softening temperature of the solder of the breaking point is reached.

Overload protector for electrical motors

A small commutator motor ( ), in particular a blower motor for motor vehicles, has a rotor shaft ( ) rotatably mounted in at least one rotor bearing ( ) in a motor housing ( ). A commutator ( ) and an armature winding ( ) electrically connected with the commutator ( ) are arranged on the rotor shaft ( ) so as to be fixed with respect to rotation relative to it. Further, brush guides ( ) for receiving brushes ( ) held in sliding contact at the commutator ( ) and an end shield ( ) which fixes the first rotor bearing ( ) in place are provided. The end shield ( ) and the brush guides ( ) are formed as a one-piece structural component part which is a component part of the motor housing ( ) as a first motor housing part ( ).
