PROBLEM TO BE SOLVED: To provide a motor that does not cause partial discharge and deterioration due to the partial discharge between windings even in driving an inverter, is equal to a conventional commercial frequency driven motor in the period of a voltage-applied service life, and does not cause short-circuiting between welded spots and between different phases of the motor windings. SOLUTION: This surge resistant motor is constituted such that: the windings of a plurality of turns are constituted of compound coated strands having insulating coatings formed on conductor strands and conductive coatings formed on surfaces of the insulating coatings; and a difference in potential between insulating coatings of the adjacent windings is alleviated by the contact of the compound strands that are adjacent via the conductive coatings.
