DEVICE FOR DIAGNOSTICS OF BEARINGS OF A LOW-VOLTAGE ELECTRIC MOTOR

摘要

A device for diagnostics of bearings of a low-voltage motor includes an electric motor, drive shaft, tested bearing with a vibro-sensor, measuring apparatuses, device for control of the value of resistance of lubrication mix, direct current power supply source, contact brushes, device for measurement of the value of resistance of lubrication mix, controller of frequency of rotation of the electric motor, pinion with inductive sensor, rubber clutch, removable bushings with sides for fixation, bearing ring, metal strip, plates for pressing. Additionally a device for control of parasitic alternating current is included, this includes an alternating current source and an alternating current indicator device.
