Abstract
The utility model discloses a voltage testing device of motor shaft, it is equipped with unable adjustment base including axle voltage probe and supporting oscilloscope on one side of the motor shaft, axle voltage probe fixed mounting is on unable adjustment base, the axle voltage probe keeps the connector contact with the motor shaft surface, oscilloscope is connected to the output of axle voltage probe, oscilloscope's ground lead ground connection. The utility model discloses set up a voltage probe on one side of the motor shaft, the axle voltage probe rotates the continuous contact in surface with the motor shaft to oscilloscope that usable and axle voltage probe are established ties detects the voltage that motor shaft both ends produced. When the epaxial voltage of motor is too big, adjust the parts of motor inside, dispatch from the factory the motor again after reducing the voltage at motor shaft both ends to the electric current that to avoid electrical axle operation in -process produced leads to the fact the galvano -cautery to bearing and ball, improves the life of motor.
Description
Technical field
The utility model relates to motor shaft structure, particularly relates to the voltage test device of motor shaft.
Background technology
In motor operation course, due to stator core combinated seam, stator silicon steel sheet seam, stator and rotor air gap uneven, motor shaft center and magnetic field center inconsistent etc., the motor shaft of motor inevitably rotates in the magnetic field of a non complete symmetry.Like this, will produce an alternating voltage at motor shaft two ends, when motor shaft two ends while, ground connection just may produce shaft current, thus causes electrocorrosion to the ball in bearing and bearing, affects the serviceable life of bearing and ball.At present, the motor shaft of motor, in operation process, cannot detect the voltage at the two ends of motor shaft.
Summary of the invention
The purpose of this utility model be to provide a kind of can to the voltage test device of the motor shaft that the voltage at motor shaft two ends detects.
For achieving the above object, the voltage test device of a kind of motor shaft of the utility model, it comprises shaft voltage probe and supporting oscillograph, firm banking is provided with in motor shaft side, described shaft voltage probe is fixedly installed on firm banking, described shaft voltage probe keeps contacting with the connection on motor shaft surface, and the output terminal of described shaft voltage probe connects oscillograph, described oscillographic ground lead ground connection.
The described shaft voltage contact contacted with motor shaft of popping one's head in adopts high density conductive fiber shaping.
Described firm banking is magnetic fixed base.
The utility model arranges shaft voltage probe in motor shaft side, shaft voltage probe contacts continuously with motor shaft rotating surface, thus the oscillograph of connecting of popping one's head in shaft voltage can be utilized to detect the voltage that motor shaft two ends produce.When the voltage on motor shaft is excessive, the parts of motor internal are adjusted, again by Motor Production Test after the voltage at reduction motor shaft two ends, to avoid the electric current produced in motor shaft operation process to cause electrocorrosion to bearing and ball, improve the serviceable life of motor.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the voltage test device of the utility model motor shaft.
Embodiment
As shown in Figure 1, the utility model comprises shaft voltage probe 3 and supporting oscillograph 4, firm banking 2 is provided with in motor shaft 1 side, described shaft voltage probe 3 is fixedly installed on firm banking 2, described shaft voltage probe 3 keeps contacting with the connection on motor shaft 1 surface, the output terminal of described shaft voltage probe 3 connects oscillograph 4, ground lead 41 ground connection of described oscillograph 4.
The contact 31 that described shaft voltage probe 3 contacts with motor shaft 1 adopts high density conductive fiber shaping, ensure that shaft voltage probe 3 contacts with the continuous of motor shaft 1.Specific to the SVP probe of the AEGIS that the present embodiment axis voltage probe 3 adopts.
Described firm banking 2 is magnetic fixed base.
The utility model arranges shaft voltage probe in motor shaft side, shaft voltage probe contacts continuously with motor shaft rotating surface, thus the oscillograph of connecting of popping one's head in shaft voltage can be utilized to detect the voltage that motor shaft two ends produce.When the voltage on motor shaft is excessive, the parts of motor internal are adjusted, again by Motor Production Test after the voltage at reduction motor shaft two ends, to avoid the electric current produced in motor shaft operation process to cause electrocorrosion to bearing and ball, improve the serviceable life of motor.
