PROBLEM TO BE SOLVED: To provide a method capable of reproducing a high-temperature test to be evaluated without using an environmental testing machine, and having productivity with reduced disturbance, compared with a conventional evaluation method. SOLUTION: When evaluation-inspecting a motor using a fluid bearing with a lubricant 3 injected between a bearing part 1 and a rotary shaft 2, the revolution number of the rotary shaft 2 is reduced compared with a normal revolution number N1 to be inspected at N2 to reproduce the lowering of shaft rigidity in accompaniment to viscosity decrease of a hydraulic fluid under an high-temperature environment, in an environment of a temperature lower than that under the evaluation-objective high-temperature environment.
