The electrical commutator motors are steel very often used machines for many applications. The advantages of this motors are cost index value, easy speed regulation and dimensions. The disadvantage is the short lifetime and service period of the sliding contact of the motor. Usually the sliding contact service period set the motor service period. The brush, brush holder and the commutator (slip-ring) are created the sliding contact. The commutator surface quality influents on sliding contact lifetime, too. Therefore the measurement workstation has been developed on our department. Measurement workstation has two main parts. The first part is table including the device, the motive machine sources and the measuring probe movement controls. The measuring frame is the second part. The measurement device including the measuring probes, the IR speed sensor, the data logger, the digital oscilloscope and personal computer with GPIB control card and Labview software. The motive device is assembly of the regulated supply and the motor. The induction analog probes are used for low distance sensing between the probe tip and electrically conducting materials.
