An electric motor includes a housing and at least one heat pipe for dissipating heat is integrated in the housing. Substantially all functional elements of the motor are disposed in the housing.

Stator housing having heat pipe with wick

A connection housing () which arranged outside on the motor housing (), receives electrical connections as well as electronic components and, with respect to the motor axis, extends peripherally and axially of the motor housing (). The connection housing () has two individual housings () which are connected to one another and whose interiors are connected.

Electric motor

A pump unit includes an electric motor, located in a stator housing (), a terminal box being arranged on an axial face of the stator housing (). The terminal box () includes a tubular housing element () having a first axial face to which the axial face of the stator housing () is connected. An opposite second axial face () of the tubular housing element () is closed by at least one cover element () into which operating and/or display elements () are integrated. An electrical connecting element () is arranged on the outer periphery of the tubular housing element ().

Pump unit

A pump assembly with an electric motor includes a stator having an iron core () and windings arranged thereon and being arranged in a stator housing surrounding the electric motor to the outside. The stator housing () is formed as a cast component, into which the iron core () is cast, and the windings have been deposited on the iron core () after the casting of the iron core () into the stator housing ().
