The present invention relates to an internal pressure explosion-proof type electric motor test apparatus and a test method of internal pressure explosion-proof using the same. The present invention provides an internal pressure explosion-proof type electric motor test apparatus and a test method of internal pressure explosion-proof using the same, including: a case with a space; a shaft installed to penetrate the case; a bearing part for supporting rotation of the shaft by being comprised between the case and the shaft; a rotor which is supported by the shaft to be able to rotate in the case and generates a magnetic force; and a stator which is comprised in an inner circumference of the case as facing the rotor, and generates a magnetic force. The bearing part includes different kinds of a first bearing and a second bearing, and the first bearing is comprised in one side of the shaft, and the second bearing is comprised in the other side of the shaft. The test apparatus can prevent work delay and can perform the work easily by reducing the number of internal pressure and explosion-proof tests, because it is not necessary to perform an internal pressure and explosion-proof test for each bearing according to the kind of the bearing, by testing different kinds of several bearings at the same time. |
