An electric motor, e.g., a fan motor for an air conditioning fan of a motor vehicle, includes a receiving housing serving as a motor housing, which has a receiving opening into which the electric motor at least partially extends, as well as including connection elements for supplying power to the electric motor, and attachment means for the electrical connection elements. The attachment for the electrical connection elements is provided on the electric motor.

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 ( ).
