Embodiment Construction

[0054] Refer below Figure 1-Figure 13 The first preferred embodiment of the present invention will be described. here, Figure 1-Figure 3 , Picture 12 with Figure 13 A general diagram of the pump unit according to this preferred embodiment is shown. The pump unit has a pump housing 2 in a known manner, in which an impeller 4 is arranged. The pump unit is designed as a centrifugal pump unit. In the embodiment shown here, the pump housing 2 is surrounded by the isolation element 6. The pump housing 2 is connected to a motor housing or a stator housing 8, and the motor housing or the stator housing is connected to the pump housing 2 in the direction of the longitudinal axis or the rotation axis X in the axial direction. An electric drive motor is provided in the stator housing 8, which has, in particular, a stator 10 and a rotor 12 rotatable in the stator. Preferably, the rotor 12 is configured as a permanent magnet rotor. The rotor 12 is connected to the impeller 4 in a ro...

Abstract

The assembly has a stator connecting element (48) and a network connecting element (62) formed as molded plastic parts, and arranged on or in an electronics housing. The connecting elements include electrical plug-in connectors (52, 66) that are connected to a corresponding electrical plug-in coupling on a printed circuit board. The connecting elements include other electrical plug-in connectors (54, 68), which are connected to the former electrical plug-in connectors via cast conductor tracks (56) and serves as an electrical connection of a component that is located outside of the housing.

Description

Technical field [0001] The invention relates to a pump unit having the characteristics described in the preamble of claim 1. Background technique [0002] A pump unit, such as a heating circulating pump unit, usually constitutes a structural unit, which includes an electric drive motor and a pump, such as a centrifugal pump. The electric drive motor is arranged in a motor housing or a stator housing, and the motor housing or the stator housing is connected with the actual pump, that is, the pump housing. The electrical and electronic devices required to control or regulate the electric drive motor are usually arranged in a junction box or an electronic device housing, and the electronic device housing is connected to the stator housing. [0003] In order to connect the coil in the stator housing to the power connection wire, and to connect other electronic devices as required, it is necessary to provide plug contacts or cable channels on the electronic device housing. For this re...
