The invention relates to an electric motor, in particular gap tubular motor, with a stator core, with a stator sheet pack penetrating and inserted into a cast resin body embedded winding and with a junction box working machine connected to the electric motor.

Because canned motors are a maintenance-free unit construction allow, they are used in almost all circulation pumps for heating systems used. For units with a lower output than There are a large number of mass products to look at Proposals to reduce the cost of the pumps. In this context, proposals have become known that the most expensive part of a centrifugal pump unit pull, especially on the stator of the wet rotor motor.

Embedding the stator core with the ones that penetrate it Windings have the problem of the loss generated in the stator dissipate heat to the environment. Against the background shown, it is now the task of the lying invention, the construction of an electric motor Generic type to evolve so that the heat drove out of the stator being improved. This task is accomplished according to a first solution proposal solved that with the stator laminated core a part non-positively or is positively connected by the casting resin, the ses part consists of a good heat-conducting material and it ver on its side facing the environment with ribs see is.

According to this proposed solution, heat transfer from Stator laminated core instead of the designated part. Training of ribs on the side of the part facing the surroundings ensures adequate heat dissipation, so that a Overheating of the unit is excluded. Here at then the connecting means between the engine and enforce the designated part of the connector housing or this be included.

The connecting means then grip into corresponding openings in the connection housing and clamp the motor and connection housing axially. According to a second proposed solution according to claim 3, a increased heat dissipation from the stator achieved in that the Stator laminated core constructed from sheets of different sizes is.

Here, the stator plates themselves form ribs better heat emission. For this purpose, rectangular sheets with, for example, round sheets to the combi stator sheet package be kidneyed. In Fig. The winding 2 passes through the stator core 1. The winding 2 is embedded in a cast resin body 3. With the stator laminated core 1 , a part 5 is non-positively or positively connected by the casting resin 3.

The part is made of a good heat-conducting material. Since a high heat dissipation from the stator core 1 to the part 5 is ensured. According to the invention, the part 5 is now provided on its side facing the environment with rip pen 6 , which enlarge the cooling surface.

If the part 5 protrudes the stator laminated core 1 in at least two positions radially not shown , the part 5 can simultaneously the connecting means 7 , shown in FIG. This can be achieved in a simple manner through a corresponding bore through the part 5. Referring to FIG. By tightening the screw 7 , the motor and the connection housing are axially clamped together.

The electric motor again has a laminated stator core 1 , through which the winding 2 passes. For the sake of simplicity, other parts of the engine are not shown. In this exemplary embodiment, the stator lamination is made up of laminations of different sizes.

As a result, the stator laminations themselves form ribs 9 for better heat dissipation. For example, rectangular sheets can be combined with round sheets. The connection between the motor housing, which can be formed at least partially by the cast resin body 3 , with the connection housing 4 of the working machine takes place in the illustrated embodiment via a form-fittingly connected to the stator core 1 connection ring 10, which is penetrated by a screw 7 , which engages in a threaded bore 8 in the connection housing 4 of the machine.

By pulling the screw 7 , the motor and the housing housing are axially clamped together. In order to improve heat dissipation from the stator of an electric motor having a winding which passes through the laminated stator core and is embedded in a cast-resin body, and having a connecting housing of the process machine, which housing is connected to the electric motor, it is proposed to connect a part to the laminated stator core either in a force-fitting manner or in a positively locking manner by means of the cast resin, this part consisting of a highly thermally conductive material and its side pointing towards the environment being provided with ribs.

As an alternative to this, an electric motor is proposed which has a laminated stator core in order to improve the heat emission from the stator, which core is constructed from laminates of different size so that the stator laminates themselves form ribs for improved heat emission. The invention is explained in more detail with reference to the drawings. Here at shows: Fig. Electric motor, in particular canned motor, with a stator laminated core, with a winding passing through the stator laminated core and embedded in a cast resin body and with a connection housing of the working machine, which is connected to the electric motor, characterized in that one with the stator laminated core 1 is non-positive or through the casting resin 3 positively connected part 5 is provided, which consists of a good heat-conducting material and the side facing the environment with ribs 6 is seen ver.

Electric motor according to claim 1, characterized in that the part 5 projects radially beyond the stator laminated core 1 at at least two points and the connecting means 7 between the motor and the connection housing 4. Electric motor, in particular canned motor with a stator laminated core, with a winding passing through the stator laminated core and embedded in a cast resin body and with a connection housing of the machine, which is connected to the electric motor, characterized in that the stator laminated core 1 consists of sheets of different sizes is built on, so that the stator plates themselves form ribs 9 for better heat dissipation.
