Three-phase A.C. motors Construction types The construction types of electric motors and their symbols comply with the standards EN 60034-7. Our motors are available in basic construction types IM B3, IM B5 and IM B14. The table shows the symbols and the installation options of the standard models we manufacture. The type IM B3 motors can also be operated in the mounting positions IM B6, IM B7 and IM B8. As well as the flange sizes allocated in line with the standard, a number of other flange sizes can also be supplied (see page 1/11). On all construction types with the shaft end at the bottom the version "with safety cover" must be selected in order to prevent foreign bodies from falling in. IP protection classes The protection classes of circulating electric machines are denoted by an abbreviation in line with EN 60034-5. It consists of the letter IP (international protection) and two numbers. 1st number ( 0 to 6 ): Protection level for contact and foreign body protection. 2nd number ( 0 to 8 ): Protection level for water protection. The motors are constructed with protection class IP 55. Motors can be supplied with a higher protection class on request. Protection from solids and liquids: IP protection class Protection class Protection from contact and the penetration of solid substances (first number) IP 55 / IP 56 Full protection from contact with live and moving internal parts. Protection from penetration from dust. The penetration of dust is not completely prevented but cannot take on such a scale as to have a negative effect on operation of the machine. IP 65* Complete protection from contact with live or moving internal parts. Penetration of dust is fully prevented. Protection class Protection from penetration of water (second number) IP 55 / IP65* The motor is protected from jets of water from all directions. IP56 Machine protected from heavy seas. Water from heavy seas or a strong jet of water must not penetrate into the housing in damaging quantities. * All vertically installed motors with an open shaft end at the top must be protected in such a way that no foreign objects can fall into the fan cover from above. However, this protection is not necessary if the machine is fitted with such a protective mechanism itself. Motors installed in the open must be protected from direct sunlight. HEW DEx series 1/9 1
