Polymer compositions, which are particularly useful in automotive applications, are described. The motor includes a stator and a rotor being rotatably received in the stator. A magnetic substance 3 is provided in the vicinity of one end of the coil member 3 to allow the magnet member 2 to exert a magnetic attractive force. When multiple tag requests are received from multiple requesters each section containing available tags may provide a tag to a requester associated with the section per clock cycle.
