2.1. The rotors of small electric motors are as a rule produced for customer requirements since it is rare for there to be a small motor which can be supplied to a second or to several customers in the same configuration.

The rotor shaft is constructed in three parts, the shaft centrepiece (12) holding the rotor laminar stack (11) and having free ends (12', 12'') which overhang the ends (13, 14) of the rotor on both sides. The one end (12') of the shaft centrepiece (12) is used in this case as a holder for the separately produced shaft stump (15) on the drive end, and the shaft stump (16) on the non-drive end, which is likewise produced separately, is mounted on the other end (12'') of the shaft centrepiece (12). ……
