A motor rotor having an insulator coated on a contact surface of a core around which a coil is wound. The insulator is formed of plastic liquid on the exterior circumference of the core by insert molding, the plastic liquid including plastic and glass fiber heated and mixed at a ratio of 80-90% by weight to 10-20% by weight.

The method involves using a predefined frame format for transferring data. The data flow between code converters (TCE1,TCE2) associated with the subscribers (Tl1,Tl2) is divided into a first data flow with sampling values for transmission and a second data flow with signal parameters for useful data reconstruction and/or signalling for transparent pass-through. The divided data flows are transferr...
