TLDR
In this article, a single-sided rotor base is used for enclosing stator as a part of motor housing with high degree of protection system of Ingress Protection 54 according to DIN/international electro-technical commission-EN 60034part 5.Abstract:
The rotor (1) has a rotor socket (2) provided with a peripheral wall (4) and a single-sided rotor base (6) for enclosing stator as a part of motor housing with high degree of protection system of Ingress Protection 54according to DIN/international electro-technical commission-EN 60034-part 5. The rotor socket comprises a heat sink (12) with high thermal conductivity such the motor heat that occurs in an inner side is discharged to surrounding area via the heat sink through the rotor base. The heat sink is formed as a single-piece disk-type cooling element (20).read more
