Frame
Frame and endshields are made of cast iron. Motor feet are cast on.For each shaft centre height only one frame length is used.To ensure optimum use of material, the finite element method was used for the design. The frame design ensures the highest possible strength, torsional rigidity, and vibrostability.
Segmental ribs and asymmetric arrangement of the terminal box make for a larger heat-radiating frame surface. In addition,
cooling ribs are arranged on the frame inside around the endwindings.Main and auxiliary terminal boxes are arranged on the
cable duct on top of the frame. Cable entry can be from any direction.
D-end and N-end endshields are identical. Endshields are ribbed inside and out for increased mechanical strength and cooling, res-pectively.
Corrosion protection
Paint systems used by us are free from lead and other heavy metals, i. e. they are toxicologically harmless.
Paint systems for long-term protection are cho-sen in accordance with site conditions to meet the requirements of climate groups MODERATE or WORLDWIDE to EN 60721.
s parameter
s Standard paint system for climate group MODERATE
Suitable for indoor and outdoor installation, normal industrial, non-corrosive atmospheres. Basis of finishing paint: Polyurethane resin s Special paint system for climate group WORLDWIDE
Suitable for outdoor installation in corrosive chemical atmospheres.Basis of finishing paint: Special plastics
Both paint systems are resistant to light, resistant to temperatures up to 120°C, non-porous, elastic, and resistant to impact and abrasion.Prior to applying the high-quality primer, intermediate and finish-ing coats either by spraying or flooding, all cast iron parts are thoroughly sandblasted to ensure excellent keying of the coatings and hence a long-term corrosion protection.

Anti-friction bearings
Our motors in basic design are fitted with Series 3 (medium) antif-riction bearings.
Exception: 2-pole frame 500 motors are always fitted with sleeve bearings.
IM B3 motors in basic design are provided at the D-end with a grooved ball bearing (locating) and at the N-end with a pre-loaded grooved ball bearing (non-locating).
For particularly high radial loads, all motors are provided with a cylindrical roller bearing at the D-end.
For lubrication, lythium-soap grease is used. All motors are fitted with standard lubricators M10x1. Outer bearing covers are designed to accommodate 5 years’ quantity of spent grease.
The shaft seal on the bearing inside is a felt ring; on the bearing out-side a labyrinth seal is used.
Shaft seals are maintenance-free. They protect the bearings against the ingress of dust and spray water, to degree of protection IP55.
Sleeve bearings
On request, all motors can be fitted with sleeve bearings. (Sleeve bearings are always provided on 2-pole frame 500 motors). All sleeve bearings are of the split, flanged type.
Depending on the bearing load in service, bear-ings with loose ring oilers (self lubrication) or with force-feed lubrication are used. Subsequent conversion from self to force-feed lubrication is possible.
Sleeve bearings are non-locating. Shaft end float is ±3 mm. On request, a locating bearing can be provided at the D-end. On the bearing inside, a floating labyrinth seal and a labyrinth ring is used. The shaft seal on the bearing outside consists of a floating laby-rinth and an additional seal.
Shaft seals are maintenance-free. They protect the bearings against the ingress of dust and spray water, to degree of protection IP55.
