Description of the Related Art When testing electrical characteristics of a motor rotor, such as insulation characteristics, pressure resistance characteristics, DC resistance, impulses, etc., it is usual to apply an electrode to the commutator of the rotor. To do. In the case of a small rotor, one end of the rotor shaft is held by an upright collet chuck, and the collet chuck is rotated by a gear motor to rotate the small rotor. The measurement is performed by applying a non-rotating electrode. In this case, since the rotor itself is relatively small and lightweight, it is not so difficult to rotate it. However, in the case of a rotor for a large motor, the weight of the rotor is drastically increased and it is not easy to rotate the rotor. That is,
At present, even in the case of a large rotor, which usually weighs 200 to 300 kg, it is common to conduct a test by applying electrodes to the commutator one by one while rotating the rotor side like a small motor rotor. is there.

, The heavy large rotor 1 is moved and lifted by a crane or the like, and is laid sideways so that the shaft 2 at one end thereof is in one bearing 3 of the large rotating device and the shaft 4 at the other end is in the other. The bearing 5 is supported and attached to a rotating device, whereby the rotor 1 itself is rotated by a considerable amount of power as shown by the arrow, and the non-rotating electrodes 8 are applied to the commutator 6 one by one to conduct the test. It was However, in such a conventional method, the moving equipment and the rotating mechanism of the large-sized rotor have to be upsized, and the electrode part to be brought into contact therewith is usually 1
Since there is only a weight of around Kg, there is a problem that it is very unreasonable in the device design and requires a large amount of power. further,
The work is dangerous because it lifts heavy objects, and at the same time, there is a restriction that workers are limited to those who have a crane license, and it takes considerable time and cost to inspect one rotor. there were.

必要とせず、そのための負担も軽減される利益がある。As described above, according to the present invention, the large-sized rotor is allowed to stand still on a pedestal or the like, and the measurement electrode side is rotated around the rotor axis outside the commutator to obtain the required Since the electrode is brought into contact with the commutator at the position, unlike the conventional case where a large and heavy rotor is attached to a large measuring device for testing, it is possible to rotate a stationary large rotor to a small size. There is a remarkable advantage that the equipment cost is greatly reduced because the measuring device is detachably attached and the test is performed. Also, a small rotary test device is mounted on the rotor shaft that is lined up on the factory floor etc. in preparation for the test. Since it can be removably attached and the test can be performed, there is a great practical effect that it does not require an installation area such as a unique moving device or large rotating device as in the conventional case. Furthermore, according to the invention, the test device is lightweight,
Since the electrodes can be rotated faster, the test time can be shortened, and the worker does not need any special qualification or license, and the burden for that is also reduced.
