Components for electric motors

Our component programm covers a wide range of parts for electric motor manufacturing.
We deliver fancowls, endshields, flanges and terminal boxes made of die-cast aluminum or cast iron in sizes IEC 56 - 400. Furthermore stator and rotor packs, aluminum housings, impellers, fan cowls, rain protection covers and a large number of other accessories are included in our component range.
Our accessories are compatible with many other  motor brands.

Die-cast aluminum

We supply in die-cast aluminum stator housings with bolt on feet as well as end shields, flange bearing shields and terminal boxes in IEC sizes 56 to 180. All parts are available unmachined from stock.
Furthermore, there are standard machined aluminum parts in smaller batches on stock. We would be pleased to deliver parts according to your specifications.
Please bear in mind that the stator housing can only be machined after the shrinking in of the stator pack.
The shrinking of the packs takes place in unmachined condition.  The empty heated housing has a temperature of 200 ° C to 250 ° C and is pushed over the stator. The pack position is usually centered. For special lengths an asymmetrical pack position is possible as well.
For the positioning of the shrunk packs an axial auxiliary stop is required.
Shrinking of the packs can also be undertaken by ourselves.
Other stator packs with the same outer diameter can also be used in addition to the standard IEC ones.
We also supply all other attachment parts such as endshields, flanges B5 / B14 and a large selection of different terminal boxes in aluminum and plastic for protection classes from IP44 to IP65.
Suitable seals are available for all terminal boxes.

Aluminium Extrusions

We offer for individual drive solutions stator housings made of extruded aluminum in sizes 56 to 132 in different designs.
Such extruded stator housings are often used for servomotors, circular saw motors and other special motors.
Another field of application for the extruded profile can be found in hydraulics as cooling containers and as  heat sinks for electronic components.
The extruded aluminum profiles can be delivered in lengths of 3 m or cut to your specific length requirements.
We would happily assist you with your own design which can be exicuted to your specification.

Cast iron

We deliver in cast iron, stator Housings, endshields as well as flange bearing shields and terminal boxes in IEC sizes 80 to 400.
The housings are available in mountings B3 and B5 with cast-on feet and laterally or top-mounted terminal boxes.
For stability the feet for the B3 housings  sizes 250 to 400 are cast with the housing and are offered without holes.
Depending on the size and shape the housings have 4 or 8 cams on both sides as standard. We also supply all other components such as endshields, flanges B5 / B14 as well as terminal boxes in cast iron for our housings. For all terminal boxes we offer the corresponding seals as well.
For smaller housings (80 to 112) we supply end shields for the A- and B-side. From size 132 a universal endshield is available for both sides.
All parts are unmachined on stock and can be delivered immediately. We are able to deliver the parts according to your specification.
Further accessories include high enertia fans in sizes 63 to 100, brake end shields in sizes 56 to 132 and bearing end covers.
All cast iron parts can also be produced in ductile iron or aluminum.
It would be our pleasure to deliver special parts according to your specific requirements in both raw or machined versions.

Stator-rotor packs

We supply stator packs and die-cast rotors in sizes 56 to 180 from our warehouse.

From sizes 200 to 355 we produce to order. All sizes are available in 2-, 4-, 6- and 8-pole versions.
For DC motors, stator packs and loose rotor laminations are available in sizes 80-4 to 132-4 poles.
The rotors can be delivered in either aluminum or silumin. The short circuit rings are equipped with wings and cams as standard.
Our stator packs are suitable for the stator housings from our product range. Special designs or special lengths can be delivered on request.
Stock articles are available in qualities M 400-50 A, M 600-50 A or M 800-50 A (depending on size and number of poles).
We would be pleased to provide you an offer for special punched or laser lengths.

Ventilation fans

For OEM’s as well as for the electric motor repair industry motors we supply PPN and aluminum fans in sizes from 56 to 355. The ventilation fans are universally used for nearly all electric motor brands.

Within our plastic range, we offer PPN ventilation fans for temperature ranges from – 20 ° C to + 90 ° C and in Ultramide / Polyamide for ambient temperatures from – 30 ° C to + 170 ° C.
In the aluminum section, finished machined ventilation fans and unmachined ventilation fans are available.

Our ventilation fans are available with keyway or clamp. (Aluminium ventilation fans – unmachined with 10 mm raw bore for customers own processing.


For increased airflow and quiet operation we also offer ventilation fans with uni-directional axial wings in plastic or aluminum. Due to the pre-selection of different profiles and angle settings, individual air outputs can be achieved. The advantage over conventional ventilation fans is that they have very high efficiency with low power consumption and noise level.
The aluminum hub is manufactured to your specifications. Different airfoils and diameters allow outer diameters from 120 mm to 2745 mm.
The wings can be made in fibreglass , reinforced plastic as well as in aluminum. Operating temperatures from – 40 ° C to 110 ° C for aluminum up to 249 ° C * (* – 60 ° C to 245 ° C depending on profile for aluminum fans)


We also deliver replacement centrifugal impellers / drum rotors and fan wheels for our radial blowers from stock or manufactured within 4-8 weeks. We manufacture radial blades in steel, stainless steel and aluminum. We are also happy to supply replacements for third-party products or as a new design for your application. Production from 1 piece to series.
