Patent DE-4023623-A1 (DE)
Inventor: SAEED ABDUL-RAHMAN DIPL ING
IPC: H02K23/04
Filed: 1990-07-25
Abstract: Proposed is an electrical machine, in particular an electrical motor, which has a rotor consisting of a hollow cylindrical armature core (11) carrying an armature (13). The stator of the electrical machine has magnet poles (23, 24) staggered by the same rotational angle. Commutation is by means of brushes (29), the armature winding (13) being designed as a commutator coil. The brushes (29) of the brush set are in sliding contact with the armature winding (13). Thus the commutation necessary for a d.c. motor, for instance, can be ensured without a commutator being fitted. The fact that the commutator and the leads connecting it to the armature winding are not necessary makes manufacture of the motor simpler and less expensive. In addition, the motor can be designed so that it is smaller, in particular shorter, and lighter for the same power.

Filed: 1992-02-26
Abstract: A test carrier for determining an analyte in whole blood comprises a test field containing a reagent system. The test field has a sample feed side on which the blood sample is placed and a detection side on which the analysis reaction gives rise to an optically detectable change.
