<p>PROBLEM TO BE SOLVED: To provide an insulating-property inspection apparatus by which the insulating-property inspection of a motor can be executed without being separated from a controller and in a short time. SOLUTION: The insulating-property inspection apparatus 10 inspects the insulating performance of motors 51 to 60 in such a way that currents are made to flow to electric power lines installed along power lines 71 to 80 of the motors 51 to 60, that relays AS1 to AS10 are changed over sequentially and that voltages of electromotive forces induced in the power lines 71 to 80 of the DC motors 51 to 60 are measured.</p> |
